INSTALL ADAPTERS TO GAS CONTROL Install adapters to gas control as follows: Flanges 1. Choose the appropriate flange for your application. 2. Remove seal over gas control inlet or outlet. 3. Ensure the O-ring is fitted in the flange groove. If the O-ring is not attached or is missing, do not use flange. 4. With O-ring facing gas control, align the screw holes on the control with the holes in the flange. Insert and tighten the screws provided with the flange. See Fig. 3. Tighten the screws to 25 inch-pounds of torque to provide a gas-tight seal. Bushings 1. Remove seal over gas control inlet or outlet. 2. Apply moderate amount of good quality pipe com- pound to bushing, leaving two end threads bare. On LP installation, use compound resistant to LP gas. Do NOT use Teflon tape. 3. Insert bushing in gas control and thread pipe carefully into bushing until tight. USING ADAPTERS TO SOLVE SWING RADIUS PROBLEMS In some field service applications, it is difficult or impossible to thread the control onto the gas supply pipe because of space limitations. This problem can be resolved in many instances by using an adapter. The adapter in installed on the end of the supply pipe in place of the gas control, following the same precautions and instructions that are used for installing the gas control. After the adapter is installed, the gas control is attached to the adapter as outlined above. Note that using an adapter increases the overall length of the gas control. CHOOSE GAS CONTROL LOCATION Do not locate the gas control where it may be affected by steam cleaning, high humidity, dripping water, corrosive chemicals, dust or grease accumulation, or excessive heat. To ensure proper operation, follow these guidelines: · Locate gas control in a well ventilated area. · Mount gas control high enough above the cabinet bottom to avoid exposure to flooding or splashing water. · Ensure the ambient temperature does not exceed the ambient temperature ratings for each component. · Cover gas control if appliance is cleaned with water, steam, or chemicals or to avoid dust and grease accumulation. · Avoid locating gas control where exposure is possible to corrosive chemical fumes or dripping water. Locate the gas control in the appliance vestibule on the gas manifold. In replacement applications, locate the gas control in the same location as the old gas control. Install Piping to Gas Control All piping must comply with local codes and ordi- nances or with the National Fuel Gas Code (ANSI Z223.1 NFPA No. 54), whichever applies. Tubing installation must comply with approved standards and practices. 1. Use new, properly reamed pipe free from chips. If tubing is used, ensure the ends are square, deburred and clean. All tubing bends must be smooth and without deformation. 2. Run pipe or tubing to the gas control. If tubing is used, obtain a tube-to-tube coupling to connect the tubing to the gas control. 3. Install sediment trap in the supply line to the gas control. See Fig. 4. 3 69-0626--2 Install Gas Control 1. This gas control can be mounted 0-90 degrees, in any direction, including vertically, from the upright position of the gas control knob. 2. Mount the gas control so gas flow is in the direction of the arrow on the bottom of the control. Fig. 4--Install sediment trap. DROP HORIZONTAL PIPED GAS SUPPLY 3 IN.

Use only your hand to turn the gas control knob. Never use any tools. 2. If the gas control knob will not operate by hand, the gas control should be replaced by a qualified service technician. GAS CONTROL KNOB SETTINGS The gas control knob has two settings: OFF prevents main burner gas flow. ON permits main burner gas flow. Under control of the thermostat and direct ignition module, gas can flow to the main burner. NOTE: Controls are shipped with the gas control knob in the ON position. PERFORM GAS LEAK TEST ! WARNING FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH Check for gas leaks with rich soap and water solution anytime work is done on a gas control. GAS LEAK TEST 1. Paint all pipe connections upstream of the gas con- trol with a rich soap and water solution. Bubbles indicate a gas leak. 2. If a gas leak is detected, tighten the pipe connection. 3. Stand clear while lighting main burner to prevent injury caused from hidden gas leaks that could cause flashback in the appliance vestibule. Light the main burner. 4. With the main burner in operation, paint all pipe joints (including adapters) and gas control inlet and outlet with rich soap and water solution. 5. If another gas leak is detected, tighten adapter screws, joints, and pipe connections. 6. Replace the part if gas leak cannot be stopped. TURN ON SYSTEM Rotate the gas control knob counterclockwise to ON. TURN ON MAIN BURNER Follow instructions provided by appliance manufac- turer or turn thermostat up to call for heat. CHECK AND ADJUST GAS INPUT TO MAIN BURNER ! CAUTION 1. Do not exceed the input rating stamped on the appliance nameplate, or manufacturer recommended burner orifice pressure for the size orifice(s) used. Ensure the main burner primary air supply is properly adjusted for complete combustion (refer to the appliance manufacturer instructions). 2. IF CHECKING GAS INPUT BY CLOCKING THE GAS METER: · Ensure that the only gas flow through the meter is that of the appliance being tested. · Ensure that other appliances are turned off and that their pilot burners are extinguished (or deduct their gas consumptions from the meter reading). · Convert the flow rate to Btuh as described in the Gas Controls Handbook (form 702602) and compare to the Btuh input rating on the appliance nameplate. 3. IF CHECKING GAS INPUT WITH A MANOMETER (PRESSURE GAUGE): · Ensure the gas control knob is in the PILOT position before removing the outlet pressure tap plug to connect the manometer. · Turn the gas control knob back to PILOT when removing the manometer and replacing outlet pressure tap plug. · Shut off the gas supply at the appliance service valve, or for LP gas at the gas tank, before removing the outlet pressure tap plug and before disconnecting the manometer to replace the outlet pressure tap plug. · Perform the Gas Leak Test at the inlet pressure tap plug. Standard-Opening and Slow-Opening Pressure Regulator 1. The gas control outlet pressure should match the manifold pressure listed on the appliance nameplate. 2. With the main burner operating, check the gas con- trol flow rate using the meter clocking method or check the gas pressure using a manometer connected to the gas control outlet pressure tap. Refer to Fig. 1. 3. If necessary, adjust the pressure regulator to match the appliance rating. Refer to Table 5 or 6 for the factory set nominal outlet pressures and adjustment ranges. a. Remove the pressure regulator adjustment cap and screw. b.

Always replace the cap screw and tighten firmly to ensure proper operation. 4. If the desired outlet gas pressure or gas flow rate cannot be achieved by adjusting the gas control, check the gas control inlet pressure using a manometer at the inlet pressure tap. If the inlet pressure is in the normal range (refer to Table 5 or 6), replace the gas control. Otherwise, take the necessary steps to provide proper gas pressure to the gas control. Step-Opening Pressure Regulator 1. The gas control outlet pressure should match the manifold pressure listed on the appliance nameplate. 2. With the main burner operating, check the gas con- trol flow rate using the meter clocking method or check the gas pressure using a manometer connected to the gas control outlet pressure tap. Refer to Fig. 1. 3. If necessary, adjust the pressure regulator to match the appliance rating. Refer to Table 5 or 6 for factory set nominal outlet pressures and adjustment ranges. a. Remove the pressure regulator adjustment cap screw. b. Using a screwdriver, turn the inner adjustment screw clockwise to increase or counter- clockwise to decrease the main burner gas pres- sure. c. Always replace the cap screw and tighten firmly to ensure proper operation. 4. If desired outlet pressure or flow rate cannot be achieved by adjusting the gas control, check the inlet pressure using a manometer at inlet pressure tap or up- stream of the gas control. If the inlet pressure is in the normal range (refer to Table 5 or 6), replace the existing gas control. Otherwise, take the necessary steps to provide proper gas pressure to the gas control. 5. Carefully check main burner lightoff at the step pressure. Ensure the main burner lights smoothly and without flashback to the orifice and that all ports remain lit. Cycle the main burner several times, allowing at least 30 seconds between cycles for the regulator to resume the step function. Repeat after allowing main burner to cool. Readjust the full rate outlet pressure, if necessary, to improve lightoff characteristics. CHECK SAFETY SHUTDOWN PERFORMANCE ! WARNING FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH Perform the safety shutdown test any time work is done on a gas system. NOTE: Read steps 1-7 below before starting and compare to the safety shutdown or safety lockout tests recommended for the direct ignition (DI) module. Where they differ, use the procedure recommended for the module. 1. Turn gas supply off. 2. Set thermostat or controller above room temperature to call for heat. 3. Watch for ignition spark or for glow at hot surface igniter either immediately or following prepurge. See DI module specifications. 4. Time length of igniter operation. See DI module specifications. 5. After the module locks out, open gas control and ensure there is no gas flow to main burner. 6. Set thermostat below room temperature and wait one minute. 7. Operate system through one complete cycle to ensure all controls operate properly. 7 69-0626--2 Maintenance Service ! WARNING FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH Improper cleaning or reassembly may cause gas leakage. When cleaning, ensure that control is reassembled properly and perform gas leak test. Regular preventive maintenance is important in applications that place a heavy load on system controls, such as in the commercial cooking and agricultural and industrial industries because: · The equipment operates 100,000-200,000 cycles per year in many such applications, particularly commercial cooking. Such heavy cycling can wear out the gas control in one to two years. · Exposure to water, dirt, chemicals and heat can damage the gas control and shut down the control system. The maintenance program should include regular checkout of the gas control, see Start-Up and Checkout, page 6, and the control system as described in the appliance manufacturer's literature. Maintenance frequency must be determined individually for each application. Some considerations are: · Cycling frequency. Appliances that may cycle 100,000 times annually should be checked monthly. · Intermittent use. Appliances that are used seasonally should be checked before shutdown and again before the next use. · Consequence of unexpected shutdown. Where the cost of an unexpected shutdown would be high, the system should be checked more often. · Dusty, wet, or corrosive environment. Since these environments can cause the gas control to deteriorate more rapidly, the system should be checked more often. The gas control should be replaced if: · It does not perform properly on checkout or trouble- shooting. · The gas control knob is hard to turn or push down, or it fails to pop back up when released. · The gas control is likely to have operated for more than 200,000 cycles. ! WARNING FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE, INJURY, OR DEATH Do not disassemble the gas control; it contains no replaceable components. Attempted disassembly or repair may damage the gas control. ! CAUTION Do not apply a jumper across or short the valve coil terminals. Doing so may burn out the heat anticipator in the thermostat or damage the DI module. IMPORTANT: Allow 60 seconds after shutdown before re-energizing step-opening model to ensure lightoff at step pressure. IF MAIN BURNER WILL NOT COME ON WITH CALL FOR HEAT 1. Ensure gas control knob is in the ON position. 2. Adjust thermostat several degrees above room temperature. 3. Using ac voltmeter, measure voltage across MV terminals at gas control. 4. If no voltage is present, check control circuit for proper operation. 5. If proper control system voltage is present, replace gas control. 8 INSTRUCTIONS TO THE HOMEOWNER FOR YOUR SAFETY, READ BEFORE OPERATING ! WARNING FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH Follow these warnings exactly: 1. Pilot flame is lit automatically. Do not light the pilot flame manually. 2. Before lighting pilot burner flame, smell around the appliance for gas. Be sure to smell next to floor because LP gas is heavier than air. 3. IF YOU SMELL GAS: · Turn off the gas supply at the appliance service valve. On LP gas systems, turn off gas supply at the gas tank. · Do not light any appliances in the house. · Do not touch electrical switches or use the phone. · Leave the building and use a neighbor's phone to call your gas supplier. · If you cannot reach your gas supplier, call the fire department. 4.
