c. Ensure that pilot burner tubing or orifice is not clogged. If clogged, replace combination gas control.
WARNINGFire or Explosion Hazard Can cause property damage, severe injury or death Perform the safety shutdown test any time work is done on a gas module.1. Place gas control knob in PILOT position. Main burner should go off and pilot should remain lit.2. Extinguish pilot flame. Pilot gas flow should stop within 2-1/2 minutes. Safety shutoff of pilot gas provides complete shutdown since safety shutoff valve blocks flow of gas to main burner and pilot.3. Relight pilot burner and operate system through one complete cycle to make sure all controls operate properly.SERVICECAUTIONDo not apply jumper across (or short) valve coil terminals, even temporarily. Doing so may burn out heat anticipator in thermostat.IMPORTANT Allow 60 seconds after shutdown before reenergizing step-opening model to ensure lightoff at step pressure.If Pilot Will Not Light1. Ensure the main gas supply valve is open and the pilot gas supply line is purged of air.2. Attempt to light pilot following procedure in “Light Pilot” on page 5. If pilot still will not light: a. Check pilot gas adjustment screw. If closed, readjust pilot flame. Refer to “Adjust Pilot Flame” on page 5. b. Perform gas leak test at compression fitting. If leak is detected, replace old compression fitting or tighten new one. Refer to “Connect Pilot Gas Tubing” on page 3.
If Pilot Goes Out When Gas Control Knob Is Released1. Make sure the gas control knob is held in at least one minute to allow the thermocouple time to heat.2. Check pilot flame adjustment, refer to “Adjust Pilot Flame” on page 5.3. Check the wiring between the thermocouple and the valve operator in the gas control.4. Ensure jumper between valve operator and power unit is secure and connections are clean.5. If pilot still goes out, measure the open and closed thermocouple circuit output voltages. Compare to acceptable range charts in the thermocouple specifications or in the Gas Controls Handbook. Replace the thermocouple if voltages are outside the acceptable range.6. Check power unit resistance. If above 11 ohms, replace gas control.If Main Burner Will Not Come On With Call For Heat1. Make sure gas control knob is in the ON position. 2. Adjust thermostat several degrees above roomtemperature. 3. Disconnect leadwires to lower left TH terminal andlower right PP terminal to isolate valve operator coil from balance of circuit. Measure resistance of coil. If coil is not 2 ohms ±10 percent, replace valve operator. 4. Measure the open and closed thermocouple output voltages and compare to acceptable range charts in the thermocouple specifications or in the Gas Controls Handbook. Replace the thermocouple if voltages are outside the acceptable range.If Burner Is OverfiringAdjust pressure regulator to correct pressure. If regulator cannot be adjusted and supply pressure is in normal range, replace complete gas control.
