Many safety-related messages have been provided in this manual and on your water heater. Always read and obey all safety messages. These messages will point out the potential hazard, tell you how to reduce the risk of injury, and tell you what will happen if the instructions are not followed. This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others. All safety messages will follow the safety alert symbol and either the word "DANGER" or "WARNING". DANGER Serious injury or death can occur if you do not follow the instructions immediately. WARNING Serious injury or death can occur if you do not follow the instructions. WARNING DO NOT use this water heater if any part has been under water. Immediately call a qualified service technician to inspect the water heater and to replace any part of the control system which has been under water. Failure to follow this instruction can result in property damage, personal injury, or death. IMPORTANT These instructions have been written as a guide for the proper installation and operation of your water heater, and the manufacturer of this water heater will not accept any liability where these instructions have not been followed. However, for your safety and to avoid damage caused by improper installation, this water heater must be installed by a Certified Licensed Professional, and meet all local codes or, in the absence of local codes, CSA C22.1 Canadian Electrical Code, in Canada, and/or the National Electrical Code, ANSI/NFPA 70, in the United States. Before proceeding with the installation instructions: 1) Inspect the water heater and its component parts for possible damage. DO NOT install or attempt to repair any damaged component parts. If you detect any damage, contact the dealer where the water heater was purchased or the manufacturer listed on the warranty card. 2) Verify that the voltage being supplied corresponds to that which is marked on the water heater rating plate. 2 INSTALLATION INSTRUCTIONS Location This water heater should be located as close as possible to a power supply and to the main use of hot water. This location must not be subject to freezing temperatures. The water heater should be positioned so that the element and thermostat access doors can be removed for inspection, adjustment, and servicing of the elements and thermostats. The drain valve must also be accessible. The water heater must be located close to a suitable free-flowing floor drain. Where a floor drain is not adjacent to the water heater, a suitable drain pan must be installed under the water heater (see Figure 1A or 1B). This drain pan should be at least two (2) inches (5.0 cm) larger than the diameter of the water heater, and at least three (3) inches (7.5 cm) deep providing access to the drain valve. This pan must be piped to a suitable drain to prevent damage to property in the event of a water leak from the piping, the relief valve, or the water heater. Sooner or later, all water heaters leak. The manufacturer, based on national building codes has given the necessary advice to prevent damage to the building. Under no circumstances is the manufacturer to be held liable for any water damage in connection with this water heater. Should this water heater be installed on carpeting, the carpeting must be protected by a wood or metal panel beneath the water heater. This panel must extend at least three (3) inches (7.6 cm) beyond the width and depth of the water heater. Should the water heater be installed in an alcove or closet, the entire floor area must be covered by the panel. Water Piping Refer to Figure 1A or 1B for a typical installation. Use of this layout should provide a trouble-free installation for the life of the water heater. Before making the plumbing connections, locate the COLD water inlet and the HOT water outlet. These fittings are both 3/4" NPT male thread. Female NPT fittings must be used during the installation. Make sure that the dip-tube is installed in the cold water inlet (Top entry Models). Install a shut-off valve close to the water heater in the cold water line. It is recommended that unions be installed in the cold and hot water lines so that the water heater can be easily disconnected, if servicing is required. When assembling the hot and cold piping to the water heater,use TeflonTM tape and wrap it clockwise around all the threads or a good food grade of pipe joint compound, and ensure all fittings are tight. It is imperative that open flame is not applied to the inlet and outlet fittings, as heat will damage or destroy the plastic lined fittings. This will result in premature failure of the fittings, which is not covered by the warranty. Temperature and Pressure-Relief Valve WARNING input rating, as shown on the water heater rating plate. It should never be plugged or removed from the opening marked for it on the water heater. If this relief valve should need to be replaced, use only a new temperature and pressure-relief valve. Never install an old or existing relief valve, as it may be damaged or inadequate for the working requirements of the new water heater. This new relief valve must meet all local codes or, at a minimum, the requirements listed above. Never install another type of valve between the relief valve and the water heater. A discharge line must be installed into the relief valve. The discharge line: · Must not be smaller than the outlet pipe size of the relief valve. · Must not terminate less than six (6) inches (15.2 cm) and not more than twelve (12) inches (30.5 cm) above a floor drain. · Must not be restricted in any way. Do not thread, cap, or in any way restrict the end of this outlet. · Must be of a material capable of withstanding 210°F (99°C) without distortion. · Must be installed to allow complete drainage of the relief valve and discharge line. · Must terminate over an adequate free-flowing drain. Pressure Build-up in a Water System When the water heater operates, the heated water expands creating a pressure build-up. This is a natural function and is one of the reasons for installing a temperature and pressure-relief valve. If the cold water supply line has a built-in water meter, check valve, or pressure reducing valve, a suitable expansion tank must be installed to prevent pressure build-up or water hammer effect, otherwise the warranty is void (see Figure 1A or 1B). An indication of pressure build-up is frequent discharges of water from the relief valve. If the relief valve discharges water on a continuous basis, it may indicate a malfunction of the relief valve, and a qualified service technician must be called to have the system checked, and the problem corrected. Filling the Water Heater WARNING NEVER operate the water heater unless it is completely filled with water. Failure to follow this instruction can result in premature failure of the water heater and its component parts that is not covered by the warranty. Check that all of the water piping connections have been made. To fill the water heater: DO NOT plug the temperature and pressure-relief valve or its discharge line. DO NOT remove the relief valve. Make sure the relief valve is properly sized for the water heater. If the relief valve continuously discharges water, call a qualified service technician to correct the problem. Failure to follow these instructions can result in property damage, personal injury, or death. To protect from excessive pressure and/or temperature, a temperature and pressure-relief valve that meets the requirements of the Standard for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, CSA 4.4, in Canada, and ANSI Z21.22, in the United States MUST BE installed by the installer when it has not been factory installed. The relief valve should have a maximum set pressure that does not exceed the hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a BTU/h rating equal to or greater than the 1) Make sure that the water heater drain valve is closed by inserting a flat head screwdriver into the slot on the head of the drain valve and turning the knob clockwise . 2) Open the cold water supply manual shut-off valve. This valve must remain open, as long as the water heater is in use. NEVER operate the water heater with the cold water supply manual shut-off valve closed. 3) To make sure the water heater is completely filled with water, open all of the hot water faucets in the house to let the air out of the water heater and plumbing system. Leave the faucets open until a constant flow of water is obtained. 4) Check all of the plumbing connections to make sure there are no leaks. 3 INSTALLATION INSTRUCTIONS Figure 1A Models with one (1) element, top entry ID No. Description 1 Hot water outlet 2 Union 3 Hot water manual shut-off valve 4 Temperature & pressure-relief valve 5 Combination outlet nipple / magnesium anode 6 Thermostat / high limit assembly 7 Element and thermostat access door 8 Screw-in element 9 Drain valve 10 Free-flowing floor drain 11 Drain pan 12 Expansion tank 13 Dip-tube 14 Check valve, water meter or pressure reducing valve 15 Cold water manual shut-off valve 16 Overflow tube 17 Union 18 Cold water intlet 3 2 1 4 18 17 16 15 14 13 5 12 6 7 11 10 8 9 Models with one (1) element, side entry ID No. Description 1 Outlet tube 18 2 Temperature & pressure-relief valve 3 Overflow tube 4 Magnesium anode 5 Thermostat / high limit assembly 17 14 13 6 Screw-in element 1 7 Element and thermostat access door 8 Free-flowing floor drain 2 9 Drain valve 3 10 Drain pan 4 11 Expansion tank 5 12 Check valve, water meter or pressure reducing valve 6 15 12 16 11 13 Cold water inlet 14 Cold water manual shut-off valve 15 Unions 7 16 Hot water outlet 10 17 Vacuum breaker 18 Hot water manual shut-off valve 9 8 4 INSTALLATION INSTRUCTIONS Figure 1B Models with two (2) elements, top entry ID No. Description 1 Check valve, water meter or pressure reducing valve 2 Cold water manual shut-off valve 3 Union 4 Cold water intlet 5 Temperature & pressure-relief valve 6 Expansion tank 7 Overflow tube 8 Dip-tube 9 Drain pan 10 Free-flowing floor drain 11 Lower element 12 Drain valve 13 Element and thermostat access doors 14 Lower thermostat 15 Magnesium anode 16 Upper element 17 Thermostat / high limit assembly 18 Hot water outlet 19 Union 20 Hot water manual shut-off valve Screw-in type element 13 16 17 13 20 19 4 5 3 18 17 2 1 6 16 15 14 12 11 7 8 9 10 Models with two (2) elements, bottom entry ID No. Description 1 Check valve, water meter or pressure reducing valve 2 Cold water manual shut-off valve 3 Union 4 Vacuum breaker 5 Temperature & pressure-relief valve 6 Expansion tank 7 Overflow tube 8 Drain pan 9 Free-flowing floor drain 10 Cold water intlet 11 Lower element 12 Drain valve 13 Element and thermostat access doors 14 Lower thermostat 15 Magnesium anode 16 Upper element 17 Thermostat / high limit assembly 18 Hot water outlet 19 Union 20 Hot water manual shut-off valve 13 5 20 4 19 5 18 17 16 15 14 3 2 1 6 7 8 9 12 10 11 INSTALLATION INSTRUCTIONS Electrical Connections WARNING This water heater uses an external electrical source for power. It must be electrically grounded in accordance with all local codes or, in the absence of local codes, CSA C22.1 Canadian Electrical Code, in Canada, and/or the National Electrical Code, ANSI/NFPA 70, in the United States. Failure to properly ground this water heater can result in property damage, personal injury, or death. This water heater must be connected on a separate fuse branch circuit. Check the water heater rating plate for the element wattage and voltage and make sure that the power supply wiring and the fusing or circuit breaker are the correct size for this water heater (see Table 1). Verify that all of the wire connections on the element and thermostat have been installed correctly, are secure, and that none of the wires are grounded, have split, or are broken (see Figure 2A, 2B or 2C). If any of the original wiring needs replacing, use only 14AWG-type, or greater wire that is approved for 221°F (105°C). To hook-up the water heater to the power supply, connect the power supply wiring to the red and black wires attached to the top thermostat (see Figure 2A, 2B or 2C). NEVER CONNECT THE POWER SUPPLY DIRECTLY ONTO THE THERMOSTAT.

Figure 2A Models with one (1) element, top entry YELLOW BLUE Insulation Blankets WARNING The manufacturer's warranty does not cover any damage or defect caused by installation, attachment, or use of any type of energy saving or other unapproved devices (other than those authorized by the manufacturer) into, onto or in conjunction with the water heater. The manufacturer will not accept any liability for loss or injury resulting from the use of such unauthorized devices. The use of unauthorized energy saving devices may shorten the life of the water heater and may result in property damage, personal injury, or death. Insulation blankets for external use on electric water heaters are not necessary. The purpose of an insulation blanket is to reduce the standby heat loss associated with the operation of storage tank water heaters. This water heater meets or exceeds the NRCAN standards with respect to insulation and standby loss requirements making an insulation blanket unnecessary. If local codes require the application of an external insulation blanket to this water heater, pay careful attention to the following so as not to restrict the proper function and operation of the water heater: DO NOT cover the operating or warning labels attached to the water heater or attempt to relocate them on the exterior of insulation blanket. DO NOT cover the element and thermostat access door or temperature and pressure-relief valve. Inspect the insulation blanket frequently.

WHAT TO DO IF YOU SMELL SMOKE · Immediately turn "OFF" the power to the water heater. · If after turning "OFF" the power the smoke continues, call your local fire department. · When the smoke has stopped, call a qualified service technician to identify and repair the problem. 8 GENERAL MAINTENANCE Start-up Procedure 1) Turn on the circuit breaker at the main service panel. 2) Make sure the fuse box or power switch (if one exists) next to the water heater is pushed to "ON". 3) If you smell smoke, refer to What to do if you smell smoke. 4) Wait one (1) hour. At this time, hot water should be available at the faucet. 5) If after one (1) hour you do not have any hot water, check that the fuse or circuit breaker is in working condition. 6) Wait another hour. If at this time you still do not have any hot water, call a qualified service technician. Note: If after one (1) hour you receive only a small amount of hot water, check that the plumbing connections are not reversed. Safety Controls This water heater is equipped with a thermostat and high limit assembly (ECO) that is located above the upper heating element. If for any reason the temperature of the water becomes excessively high, the ECO will break the power circuit to the heating element. Once the control opens, it must be reset manually. To reset the ECO: 1) Turn "OFF" the power to the water heater. 2) Remove the upper element and thermostat access door and the insulation. 3) Press the red RESET button. 4) Replace the insulation and the element and thermostat access door before turning "ON" the power to the water heater. Water Temperature Regulation WARNING The higher the setting, the greater the risk of scalding. Hot water can cause third degree burns in under one (1) second at 160°F (71°C), in six (6) seconds at 140°F (60°C), and in thirty (30) seconds at 130°F (54°C). In households where there are children, physically challenged individuals, or elderly persons, mixing valves for point of use are necessary as means of reducing the scalding potential of hot water. The thermostat is factory set at 140°F (60°C) for Canadian models and 125°F (52°C) for U.S. models. To adjust the temperature on the thermostat: 1) Turn "OFF" the power to the water heater. 2) Remove the element and thermostat access door and the insulation. On U.S. models DO NOT remove the thermostat protective cover. 3) Using a small flathead screwdriver, turn the thermostat dial to the desired temperature. 4) Replace the insulation and the element and thermostat access door before turning "ON" the power to the water heater. Condensation Condensation can form on the surface of the water heater: 1) When the water heater is filled with cold water for the first time. 2) If the water heater has been undersized. 3) When large amounts of hot water are drawn from the water heater in a short period of time, and the refill water is very cold. This condition is not uncommon and must never be misinterpreted as a leaking tank. It will disappear once the water becomes heated. Because the water can condense, it is very important that a drain pan be installed under the water heater (refer to Figure 1A or 1B). Under no circumstances is the manufacturer to be held liable for any water damage, in connection with this water heater. If the problem does not go away and water continues to drip after the water heater has heated up, check all of the plumbing connections to make sure they are not leaking. Element or Thermostat Replacement WARNING Before attempting to repair or replace any of the electrical components on this water heater, turn "OFF" the power to the water heater. Failure to do so could result in electrical shock and/ or property damage, personal injury, or death. Replacing an Element (See Figure 3) 1) Turn "OFF" the power to the water heater and drain all of the water from the water heater (see Draining the Water Heater, page 11). 2) Remove the element and thermostat access door and the insulation. 3) Disconnect the wires from the element terminals. 4) For a square flange element, undo the four (4) bolts securing the element to the water heater. For a screw-in element, with the help of a 1.5 inch socket wrench, remove the element by unscrewing it from the water heater in a counterclockwise motion. For TWIST-LOCK system, unscrew the four (4) bolts securing the element to the water heater and pull element out of the tank. Make sure the TWIST-LOCK flange is in the right position (See Figure 4). 5) Replace the element with a new element of the same wattage and voltage. Make sure that the gasket surface is clean and that the element has been re-installed water-tight with a new gasket. 6) Re-connect the wiring and tighten securely. 7) Re-fill the water heater (see Filing the Water Heater, page 3). DO NOT TURN THE POWER ON TO THE WATER HEATER UNLESS YOU ARE SURE IT IS COMPLETELY FILLED WITH WATER. 8) Inspect for any leaks and repair, if necessary 9) Replace the insulation and element and thermostat access door before turning "ON" the power to the water heater. 9 GENERAL MAINTENANCE Figure 3 Screw-in element 03G, 3AG and 04G Models 1 4 5 2 3 Figure 4 6 1 - Access door 2 - Thermostat Bracket 3 - Thermostat 4 - Element 5 - Gasket 6 - Screw-in flange Square flange element 09G, 9AG, 10G, 11G, 12G and 13G Models (Until December 2012) 1 2 3 4 5 6 1 - Access door 2 - Thermostat Bracket 3 - Thermostat 4 - Element 5 - Gasket 6 - Square flange TWIST-LOCK flange element 09G, 9AG, 10G, 11G, 12G and 13G Models 1 2 3 4 5 6 1 - Access door 2 - Thermostat Bracket 3 - Thermostat 4 - Element 5 - Gasket 6 - TWIST-LOCK flange Replacing a Thermostat (See Figure 3) 1) Turn "OFF" the power to the water heater. 2) Remove the element and thermostat access door and the insulation. 3) Disconnect the wires from the thermostat terminals. 4) Lift the thermostat bracket arms and slide the thermostat up to remove it. 5) Replace the thermostat with a new thermostat of the same manufacturer and type. 6) Reconnect the wires on the thermostat terminals referring to the corresponding wiring diagram in Figure 2. 7) Set the thermostat to the desired temperature (see Water Temperature Regulation, page 9). 8) Replace the insulation and element and the thermostat access door before turning "ON" the power to the water heater. Temperature and Pressure-Relief Valve Manually operate the temperature and pressure-relief valve at least once a year, standing clear of the outlet to avoid being burned. Lift and release the operating lever on the valve to make it operate freely. If, after manually operating the valve, it fails to completely reset itself and continues to discharge water, replace it with a new one. Anode This water heater is equipped with an anode that is designed to prolong the life of the glass-lined tank. The anode is slowly consumed, protecting the glass-lined tank from corrosion. The anode should be inspected every two (2) years. If more than half of the anode has been consumed, it should be replaced. Instructions on how to change the anode can be obtained from the manufacturer. The life expectancy of the water heater is reduced where a water softener is introduced to fight hard water. The sodium salts added by a softener make the water extremely conductive, therefore, the anode are consumed more rapidly. Under these conditions, the magnesium anode must be replaced by an aluminum anode approved by Giant, along with the addition of zinc pellets. In certain water conditions, the anode will react with the water, producing discoloured or smelly water. The most common complaint is hot water that smells like rotten eggs. This phenomenon is the result of the reaction between the magnesium of the anode and hydrogen sulfide gas dissolved in the water, which occurs frequently in well systems. This problem can usually be eliminated or reduced 10 GENERAL MAINTENANCE by changing the magnesium anode to a type more suitable for these conditions (aluminum anode) and by chlorinating the water heater and plumbing system. If the problem persists, special filtration equipment may be required. Under no circumstances is the anode to be removed from the water heater on a permanent basis. Removal of the anode will lead to premature failure of the water heater and void the warranty. WARNING Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two [2] weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE. It is highly recommended to open the hot water faucet in the kitchen for several minutes before you use any electrical appliances connected to the hot water system, such as a dishwasher or washing machine. If hydrogen gas is present, there will be an unusual sound, such as air escaping through the pipe, as the hot water faucet is opened. DO NOT smoke or introduce an open flame near the faucet when it is opened. Draining the Water Heater Drain a pail of water through the drain valve at least once a year. This will remove excess sediment from the bottom of the tank. This sediment, if allowed to accumulate, will reduce the efficiency and the life of the tank. Getting Service for your Water Heater If you are having problems with your water heater, follow these three easy steps: 1) Read the Troubleshooting Guide contained in this manual (see Page 14). It lists the most common problems experienced with your electric water heater. The solutions you find listed may provide a quick and simple solution to your problem and save you time and money. 2) If the solution listed in the Troubleshooting Guide does not solve the problem or if your particular problem is not listed in the guide, contact the installer of the water heater, or the local electric utility. 3) If you still cannot solve the problem, contact the manufacturer's Customer Service Department by e-mail at service@giantinc. com or by telephone at 1-800-363-9354, option 1. To help serve you in a quick and efficient manner, always have the following information ready: a) Model number. b) Serial number. c) Date of installation. d) Where the water heater was purchased. e) Complete address where the water heater is installed. f) A description of the problem. To completely drain the water heater: 1) Turn "OFF" the power to the water heater. 2) Close the cold water supply manual shut-off valve. 3) Connect one end of a garden hose to the water heater drain valve and put the other end next to a free-flowing drain. 4) Open the drain valve by inserting a flat head screwdriver into the slot on the head of the drain valve and turning the knob counterclockwise . 5) Open a hot water faucet to allow air into the system. Vacation If you are planning a vacation or other prolonged absence, it is essential to turn "OFF" the power to the water heater and the cold water supply to the water heater. This preventive action will save energy, protect against property damage in the event the water heater leaks, and prevent the build-up of hydrogen gas. If the water heater and piping are exposed to freezing temperatures, they should both be drained. Remember to check the water heater thoroughly after it has been shut off for an extended period of time before putting it back in operation. Make sure that the water heater is completely full of water, and that the cold water supply manual shut-off valve is open, before turning "ON" the power to the water heater. 11 REPLACEMENT PARTS Figure 5A Model with one (1) element, top entry ID No. Description 1 Thermostat / high limit assembly 2 High limit with manual reset 3 Thermostat 4 Element and thermostat access door 10 11 5 Screw-in element gasket 6 Screw-in element 7 Thermostat bracket for screw-in element 8 Drain valve 9 Dip-tube 1 10 Temperature & pressure-relief valve 2 11 Combination outlet nipple/magnesium anode 3 4 9 67 8 5 Models with one (1) element, side entry ID No. Description 1 Thermostat / high limit assembly 2 High limit with manual reset 3 Thermostat 4 Element and thermostat access door 5 Screw-in element gasket 6 Screw-in element 7 Thermostat bracket for screw-in element 8 Inlet nipple 9 Outlet nipple with tube 10 Magnesium anode 11 Temperature & pressure-relief valve 11 12 3 4 67 5 12 10 9 8 REPLACEMENT PARTS Figure 5B Models with two (2) elements, top entry ID No. Description 1 Thermostat / High limit assembly 2a High limit with manual reset 2b Thermostat 3 TWIST-LOCK Flanges 4 Element gaskets 5 Upper element 6 Drain valve 7 Lower Thermostat 8 Thermostat brackets 9 Machine bolts 10 Element and thermostat access doors 11 Lower element 12 Dip tube 13 Magnesium anode 15 Temperature & pressure-relief valve 16 Outlet nipple Screw-in type element 10 5 8 1 14 15 2b 2a 1 54 3 10 8 9 76 11 13 12 Models with two (2) elements, bottom entry ID No. Description 1 Thermostat / High limit assembly 2a High limit with manual reset 2b Thermostat 3 TWIST-LOCK Flanges 4 Element gaskets 5 Upper element 6 Drain valve 7 Lower Thermostat 8 Thermostat brackets 9 Machine bolts 10 Element and thermostat access doors 11 Lower element 12 Inlet nipple 13 Magnesium anode 14 Outlet nipple 15 Temperature & pressure-relief valve 15 14 2b 2a 1 3 13 5 4 10 6 9 8 7 12 11 13 TROUBLESHOOTING GUIDE CONDITION No hot water.

Furthermore, any replacement unit or component part supplied under warranty will carry only the warranty remaining portion, based on the original unit installation date. However, the warranty is limited to one (1) replacement unit. If due to some unusual circumstance, a replacement unit or component part is found to be defective by our inspection department, another unit or component part will be provided in order to fulfill the obligation of the original warranty. This warranty applies only to the original owner that purchased the unit, to the unit original installation location, and it is not transferable. In order to benefit from this warranty, the warranty reply card must be completed and sent back to GIANT within forty-five (45) days of the unit purchase date, otherwise the warranty will be as follows: SIX (6) years (for a residential water heater in a family dwelling), FIVE (5) years (for a storage tank in a family dwelling) and ONE (1) year (for any installation other than a family dwelling) from the manufacturing date, without exception. THE INNER TANK If the warranty card is returned within the applicable time frame and the inner tank leaks within the shorter of the two following periods: SIX (6)1 years after the original installation date or NINETY (90)2 months after the manufacturing date, whichever comes first, a replacement unit will be provided to the original unit owner. Use of the equipment for purposes other than for a family dwelling limits the warranty to ONE (1) year. Exceptions: 1 : Or FIVE (5) years for storage tanks 2 : Or SEVENTY-EIGHT (78) months for storage tanks COMPONENT PARTS If any component part is found to be defective within ONE (1) year from the original installation date, provided said defective part is an in-house factory made piece or an original factory approved OEM piece, the manufacturer will provide a replacement part after the receipt and testing of such part. THIS WARRANTY DOES NOT APPLY IN THE FOLLOWING CASES: 1) To defects or malfunctions resulting from failure to properly install, operate, or maintain the unit in accordance with the Owner's Manual. 2) If the installation does not comply with CSA Standards, in particular, but not limited to, the existing CAN/CSA-C652 Standard (Installation of Electric Storage Tank and Heat Pump Water Heaters for Residential Use), CAN/CSA-B149.1 (Natural gas and propane installation code) as well as any other existing codes or standards, local regulations, and good practices. 3) To any damage or failure caused by abuse, fire, floods, freezing, or other acts of God. 4) To any damage or failure caused by operating the unit without an approved temperature & pressure-relief valve having been installed. 5) To any damage or failure caused by powering any energy source while the equipment is empty or partially empty or contains sediment buildup resulting in dry firing of the heating elements. 6) To any damage or failure caused by connecting the unit to any other source of energy not approved by GIANT or by operating the equipment for other use than with potable water without any additives such as salt, chlorine, or chemicals other than those added for the purpose of rendering the water fit to drink. 7) To any damage or failure caused by the removal of the anode and/or by not assuring that there is a working anode in the unit at all times. ``All anodes must be checked at least once every two (2) years & replaced, if necessary''. The installation of an anode that does not comply with the requirements of the existing CAN/CSA-C309 Standard (Performance Requirements for Glass-Lined Storage Tanks for Household Hot Water Service), particularly in regards to the manufacturing, installation, and composition of the replacement anode, will instantly void the warranty. The same applies, but is not limited to, the non-compliance of the CAN/CSA-C191, CAN/CSA-C22.2, and CAN/CSA-B149.1 Standards. 8) To any damage or failure caused by the use of the unit with a water softener if the magnesium anode has not been replaced by an aluminum anode approved by GIANT, as well as the addition of zinc pellets. 9) To any damage or failure caused by having affixed to the unit any non-factory made or factory approved replacement part(s), such as elements, controls, dip-tubes, anode, induced-current anode, relief valves, etc. 10) To any damage caused by not having the unit installed adjacent to a free-flowing drain or in a pan or basin connected to such free-flowing drain. 11) For all equipment operated at water temperatures exceeding the maximum operating setting of the thermostat and/or the high limit control, at a pressure exceeding the one listed on the rating plate, for equipment subject to a water-hammer effect that reverses the bottom of the tank, units that are installed in a closed-looped system without any adequate expansion tank3 being installed as well as equipment installed in a system equipped with a backflow preventer, a pressurereducing valve, or any other device, such as a check valve, without an adequate expansion tank being installed. 3 : Or any other method accepted by the competent authority. 12) To any unit drained for wintering purposes. 13) To any performance issue caused by the poor selection of equipment, power supply, wiring, or fuse / breaker. 14) To any unit from which the rating plate has been removed or altered. 15) To any break or damage caused by a water-hammer effect coming from, but not limited to, a quick-closing valve, a solenoid valve, or any other valves without an adequate pre-fabricated expansion tank being installed in compliance with existing codes, standards, and good practices. 16) To any issue caused by the installation of water connections not compatible with the equipment input and output ``NPT'' connections. 17) To any unit installed outside of Canada or the United States. SERVICE LABOUR RESPONSIBILITY This warranty does not cover any labour expense for diagnostic, service, removal, or re-installation of a replacement unit. All such expenses are the responsibility of the unit owner. SHIPPING COSTS If a unit or component part is deemed to be replaced, the manufacturer will pay the transportation costs to ship said replacement unit or part to a convenient authorized distributor or retailer of our choice. The unit owner must pay for any local cartage including the cost of returning the replaced unit or component part to the authorized distributor or retailer. CLAIM PROCEDURE Any claim covered by the warranty must be made to GIANT within a maximum of thirty (30) days from the date the defect is first discovered. Failure to provide a written notice for such defect to the manufacturer within the allocated time frame will void the warranty. Any claim for warranty service should be made with your contractor, wholesaler, or retailer from whom the unit was purchased. In turn, said contractor, wholesaler, or retailer will contact the manufacturer. If this procedure cannot be followed, please contact a local contractor, wholesaler, or retailer distributing our products. For further warranty information, please call our customer service department at (514) 645-8893 or 1-800-363-9354, option 1.

Proof of purchase showing the date and name of the business from whom the unit was purchased is mandatory if the manufacturing date goes beyond the warranty period offered by the manufacturer. If an exact replacement unit is unavailable for whatever reason such as, but not limited to, changes in government standards, the manufacturer agrees to provide a unit or component part with comparable features. If government regulations or industry standards require the replacement unit or component part to have features not found on the defective unit or component part, the unit owner will be charged the difference in price associated with these required features. If such owner pays the difference in price for these required features, they will benefit from a complete new Standard Basic Limited Warranty for the replacement unit. MISCELLANEOUS No one is authorized to modify any conditions of this actual warranty. The manufacturer will not honour any other warranty of any kind other than what is offered. No claims for incidental or consequential damage (including damage from leakage) will be accepted. If the warranty card is not returned to us, a proof of purchase showing the name, date, and location of the original point of purchase is mandatory to process any warranty claim. Failure to provide such documentation will result in the lesser of the warranty periods being offered, as stated in the ``GENERAL'' section. In order to avoid any confusion and/or disputes, we suggest that the warranty card be completed and returned to us no later than forty-five (45) days after installation.
