These regulations shall be carefully followed in all cases. Authorities having jurisdiction shall be consulted before the installations are made. All wiring on storage tanks must be in accordance with the National Electrical Code (latest edition) and/or local regulations in the US, and in accordance with the Canadian Electrical Code (latest edition) and/or local regulations in Canada. Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury, or loss of life. Read and understand the entire manual before attempting installation, start-up, operation, or service. Installation and service must be performed only by an experienced, skilled installer or service agency. This storage tank contains very hot water under high pressure. Do not unscrew any pipe fittings or attempt to disconnect any components of this storage tank without positively assuring that the water is cool and has no pressure. Always wear protective clothing and equipment when installing, starting up or servicing this storage tank to prevent scalding injuries. Do not rely on the pressure and temperature gauges to determine the temperature and pressure of the storage tank. This storage tank contains components that become very hot when the boiler is operating. Do not touch any components unless they are cool. Failure to follow all instructions in the proper order can cause personal injury or death. Read all instructions, including all those contained in component manufacturers' manuals before installing, starting up, operating, maintaining, or servicing the storage tank. To reduce the risk of excessive pressures and temperatures in this storage tank, install temperature and pressure protective equipment required by local codes but no less than a combination temperature relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-latest edition. This valve must be marked with a maximum set pressure not to exceed the marked working pressure of the storage tank. Install the valve into an opening provide and marked for this purpose in the storage tank and orient it or provide tubing so that any discharge from the valve will exit only within 6 inches above, or at any distance below, the structural floor, and cannot contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Improper water quality will reduce the life of the storage tank. Hard water, sediment, high or low PH and high levels of chlorides in the domestic water should be avoided. Be sure that PH levels fall between 6 and 8 and dissolved chlorides are less than 100 ppm. A filter must be used where sediment is greater than 5 microns in size in the water supplied to the unit. A water softening system is recommended for areas with hard water. In cases where water quality is unknown, a qualified water treatment expert should be consulted. NOTICE: Damage to tanks caused by improper water quality is not covered under the warranty. DO NOT store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance. If you smell gas vapors, DO NOT try to operate any appliance - DO NOT touch any electrical switch or use any phone in the building. Immediately, call the gas supplier from a remotely located phone. Follow the gas supplier's instructions or if the supplier is unavailable, contact the fire department. Do not operate any appliance until the leakage is corrected. This storage tank is supplied with an adjustable thermostat to control the water temperature. Hot water temperatures required for automatic dishwashers and laundry use can cause scald burns resulting in serious personal injury and/or death. The temperature at which injury occurs varies with the person's age and the time of exposure. The slower response time of disabled persons increases the hazard to them. NEVER allow small children to use a hot water tap or to draw their own bath water. NEVER leave a child or disabled person unattended in a bathtub or a shower. Page | 1 IMPORTANT SAFETY INSTRUCTIONS READ ALL INSTRUCTIONS BEFORE USING THIS STORAGE TANK. WARNING When using electrical appliances, safety precautions should be taken to reduce the risks of fire, electric shock, and injury. These precautions include the following: · This storage tank must be grounded. Connect only to a properly grounded outlet. See "GROUNDING INSTRUCTIONS" found in Section IV. · Install or locate this storage tank only in accordance with the provided installation instructions. · Use this storage tank only for its intended use as described in this manual. · Do not use an extension cord set with this storage tank.

Contact nearest authorized service facility for examination, repair, or adjustment. SAVE THESE INSTRUCTIONS Page | 2 Page | 3 Pre-installation Considerations Inspect shipment carefully for signs of damage. All equipment is carefully inspected and packed. Heat-flo's responsibility ceases upon delivery of the storage tank to the carrier in good condition. Any claims for damage or shortage must be filed immediately against the carrier by the consignee. No claims for variances or shortages will be allowed by the Manufacturer unless they are presented within sixty days after receipt of the equipment. Installation must conform to the requirements of the authority having jurisdiction. In the absence of such requirements, installation must conform to the National Plumbing Code and the National Electrical Code ANSI/NFPA No. 70 (current edition). IMPORTANT CONSIDERATIONS BEFORE INSTALLATION 1. Tank sizing: Choose the storage tank model based on the expected water usage for the given site. Factors that increase water demand dramatically include high flow shower heads, hot tubs, and the use of more than one shower at a time. Increase the tank size if these factors are present. Consult ASHRAE sizing guides and other references. LOCATING THE STORAGE TANK The storage tank should be located in an area where water leakage from the tank or connections will not result in damage to areas adjacent to the storage tank or to lower floors of the structure. When such a location cannot be avoided, a suitable drain pan must be installed under the storage tank, and the drain pan must be connected to a drain. The drain pan depth must be suitable for draining and collecting water. The piping to drain must be at least 3/4" diameter and be pitched for proper drainage. The storage tank should be installed as close to the boiler as is practical for easy access for service. The unit is designed for installation on combustible flooring and in alcoves, closets, etc. The minimum clearances from combustible surfaces are: Bottom 0" Left, Right, and Rear Sides 1" Front 1" Top 6" The minimum clearances for service are: Bottom 0" Left, Right, and Rear Sides 3" Front 30" Top 6" Page | 4 ADDITIONAL RECOMMENDED COMPONENTS 1. Shut-Off Valves: Allows the isolation of the storage tank from the boiler system during service. 2. Unions: Allows for easy locating or removal. 3. Vacuum Breaker: Protects the storage tank from collapse if a hot tank is valved off to service other components in the system. 4. Thermal expansion tank. If the storage tank is installed in a closed water supply system, such as a system having a back flow preventer, a check valve, or a pressure reducing valve in the cold-water supply line, the installation of a thermal expansion tank is required. For California installation this storage tank must be braced, anchored, or strapped to avoid falling or moving during an earthquake. See instructions for correct installation procedures. Instructions may be obtained from the California Office of the State Architect. Water Quality Improper water quality will reduce the expected life of the storage tank. Hard water, sediment, high or low Ph, and high levels of chlorides in the domestic water should be avoided. Sediment and hard water will eventually coat the heating coil inside the storage tank and reduce the rate of hot water production and may eventually cause a failure. High or low Ph and/or high chloride concentrations will cause corrosion and eventually failure. A filter is strongly recommended where sediment is present in the water. In an area where the water quality is not known, a water quality test should be performed. WARNING: Do not operate the Heat-flo storage tanks in areas where the Ph is above 8.0 or below 6.0, and/or with chloride concentrations greater than 100 parts per million (ppm). Heat-flo's standard warranty does not cover problems caused by improper water Ph or excessive levels of chlorides. Damage to tanks caused by improper water quality is not covered under the warranty. PIPING DOMESTIC WATER PIPING (See Figure 1, Pg. 3) 1. Drain the domestic water system. · Shut off the cold-water supply at the main shutoff valve. · Open one or more faucets to relieve the pressure. · Open the system drain, leaving the faucets open. 2. Position the storage tank in its final location. 3. Connect the cold-water supply piping. Page | 5 · Install piping onto cold inlet connection. · Connect to cold water supply connection using a union, a heat trap, a shut-off valve, a vacuum breaker, an expansion tank (where required), and a filter (recommended to prevent sediment buildup). If installing on a city supply, a properly sized thermal expansion tank is required and should be installed in accordance with the product installation manual. If a storage tank is installed in a closed water supply system, such as one having a backflow preventer in the cold water supply, a check valve in the cold water supply, or a pressure reducing valve in the cold water supply means shall be provided to control thermal expansion. The appliance, when installed, must be grounded in accordance with the local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70. If this product is connected to a cold-water supply line that has a check valve, a backflow preventer, a pressure reducing valve, or a check valve in the water meter, it is a requirement that a properly sized thermal expansion tank be installed in the cold water inlet line. There will be no warranty on applications where there is no pressure control. 4. Connect the domestic hot water piping. · Install piping onto hot water supply connection using a union, a heat trap, and a shut off valve. · Pipe the relief valve discharge so that the discharge from the valve will exit only within 6 inches above, or at any distance below, the structural floor and so that it cannot contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Install a discharge line so that water discharged from the temperature and pressure relief valve will exit within six (6) inches above, or any distance below, the structural floor and cannot contact any live electrical part. The discharge line is to be installed to allow for complete drainage of both the temperature and pressure relief valve and the discharge line. The discharge opening must not be subjected to blockage or freezing. DO NOT thread, plug, or cap the discharge line. It is recommended that a minimum clearance of four (4) inches be provided on the side of the storage tank for servicing and maintenance of the combination temperature and pressure relief valve. Do not place a valve between the combination temperature and pressure relief valve and the tank! 5. Fill the storage tank. · Open all faucets to allow air to purge from the tank and piping. Remove screens on faucets. Page | 6 · Open domestic hot water shut-off valve. · Open cold-water inlet shut-off valve. · Purge all of the air from the domestic water system. Allow water to run so the tank is completely purged of any debris. Run the water long enough to change at least five tank volume changes. · Close all faucets. Reinstall all of the screens in the faucets. · Check the system for leaks. Repair as required. STARTUP OPERATION After the storage tank has been plumbed and wired and the boiler water piping is purged of air, the storage tank is ready to be started. 1. The tank thermostat is factory pre-set to 125 degrees F and will call for heat if the water in the tank is lower than that (125 deg. F). 2. On a call for heat, the tank thermostat contacts close to start the circulator. 3. After the tank has reached the temperature setting, the tank thermostat opens and deenergizes the circulator. - SCALDING! This storage tank can deliver scalding temperature water at any faucet in the system. Be careful when using hot water to avoid scalding injury. By setting the thermostat on this storage tank to obtain an increased water temperature, you create the potential for scald injury. To protect against injury, you should install an ASSE approved mixing valve (a device to limit the temperature of water to protect against scald injury via mixing hot and cold-water supply) in the water system. This valve will reduce point of discharge temperature in branch supply lines. Such valves are available from a local plumbing supplier. Please consult with a plumbing professional. SCALD RELATIONSHIPS The tank thermostat controls the maximum water temperature in the storage tank. If it is set too high, the resulting hot water can cause painful scalding with possible serious and permanent injury. The temperature at which this occurs varies with a person's age, and the length of time in contact with the hot water. The slower response time of infants, older, or handicapped people increase the hazard for them. Page | 7 WATER TEMPERATURE ADJUSTMENT It is recommended that the thermostat be set for the lowest possible temperature that satisfies your needs. This will also provide you with the lowest energy consumption and cost. Check the water temperature at a hot water faucet soon after the tank thermostat has satisfied, and the circulator and the boiler have turned off. Adjust as needed. Lowering the thermostat setting will not have an immediate effect on the water temperature because the stored water will have to be used and the thermostat must go through the cycle of heating cold water and satisfying at the new, lower temperature. Additional temperature checks should follow the completion of a heating cycle. Further adjustments may be required after you have used the storage tank. The table below details the approximate relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications. The scald label shown to the right can be found on all Heat-flo Indirect Storage tanks and Storage tanks. Take note and use caution when adjusting the temperature settings with your water system. Be sure to always feel the water before bathing or showering, especially when drawing a bath for an infant or elder. Important WARNING information on the following page. Page | 8 It is the responsibility of the installing contractor to see that all controls are correctly installed and are operating properly when the installation is complete. DO NOT operate the storage tank with jumpered or absent controls or safety devices. DO NOT tamper with or alter the storage tank and/ or controls. DO NOT operate the storage tank if any external part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system that is or had been under water. DO NOT install this storage tank on carpeting. This storage tank is suitable for installation on combustible flooring. DO NOT operate this storage tank without first being certain it is filled with water. MAINTENANCE The storage tank is intended to provide many years of reliable service. Components, such as thermostats and relief valves, may be subject to failures that require service. Depending on the quality of the water supply, sediment and/or scale may coat the heating coil in the tank and reduce hot water recovery rate. Failure to use the correct procedures or parts can result in unsafe operation. The owner should arrange to have the following inspections and simple maintenance procedures done at the suggested frequencies. 1. Domestic Water Piping (Annual) · Check all piping for signs of leakage at the joints, unions and shut-off valves. Repair as required. 2. Temperature and Pressure Relief Valve (Annual) · The temperature and pressure relief valve should be checked to ensure that it is in operating condition. To check the relief valve, lift the lever at the end of the valve several times. The valve should seat properly and operate freely. If water does not flow, remove and inspect for obstructions or corrosion. Replace with a new valve of the recommended capacity as necessary. Do not attempt to repair the valve, as this could result in improper operation and a tank explosion. In areas with poor water conditions, it may be necessary to inspect the temperature and pressure relief valve more often than once a year. Before manually operating the valve, make sure that a drain line has been attached to the valve to direct the discharge to an open drain. Failure to take this precaution could mean contact with extremely hot water discharging from the valve during this checking operation. If the temperature and pressure relief valve on the heater discharges periodically or continuously, it may be due to thermal expansion of water in a closed water supply system, or it may be due to a faulty relief valve. Thermal expansion is the normal response of water when it is heated. In a closed system, thermal expansion will cause the system pressure to build until the relief valve actuation pressure is equaled. Then the relief valve will open, allowing some water to escape, slightly lowering the pressure. Contact your water supplier or local plumbing inspector on how to control this situation. Page | 9 ABOVE ALL, DO NOT PLUG THE TEMPERATURE AND PRESSURE RELIEF VALVE. THIS IS NOT A SOLUTION AND CAN CREATE A HAZARDOUS SITUATION. 3. Sediment (Annual except where harsh water quality may require more frequent service) · Depending on water conditions, a varying amount of sediment may collect in the tank. Levels requiring service are indicated by a small temperature difference between the boiler supply and return lines, and a reduced recovery rate. Repeated flushing usually clears such material. As a preventive measure, water should be drawn from the drain valve until it runs clear, and the installation of a water filter should be considered. 4. Inspect Anode (annual) · The purpose of the magnesium anode is to reduce the damaging effects of aggressive water on the storage tank. Aggressive water will cause the anode(s) to erode. The anode(s) must be inspected at least annually to determine whether a new anode should be installed. Use anode replacement parts supplied by Heat-flo only. Heat-flo anodes are 1-1/4 NPT and are made with magnesium, brass, and stainless steel. There is no steel in a Heat-flo anode. Severe or rapid deterioration of the anode indicates very aggressive water. If this occurs, have the water tested to verify whether it is within the limits outlined on page 6. Failure to inspect the anode regularly and replace if necessary, could result in damage to the storage tank. If this unit is installed and maintained according to the instructions and conditions in this manual, this product will last for a long time. 1. Close domestic water isolation valves. 2. Drain the storage tank completely and allow it to cool off. 3. Remove the anode cover on the front of the unit. The temperature control can be turned to the side to allow easier access. 4. After the storage tank has drained and cooled, remove the anode using a 1 ¾" 6-point socket and a breaker bar. 5. Inspect the anode and replace if needed. The anode should be replaced when more than 6" of core wire is exposed. The anode should be replaced with a Heat-flo supplied anode only. See above. The brass hex on the anode is 1 ¼ NPT and installs into a 1 ¼ stainless half coupling on the shell of the tank. This part will need to be properly Teflon taped and coated with a quality Teflon based pipe sealant. 6. Replace the inspection cover. 7. Refill the storage tank and restore to operation. 8. Verify operation of boiler and storage tank. Page | 10 Heat-flo, LLC. LIMITED WARRANTY Storage Tanks Your tank is protected by these Heat-flo, LLC., (HFL), warranties.
