Check Safety Shutdown 
Performance
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.
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 proves 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.
SERVICE
Fire or Explosion Hazard can cause property 
damage, severe injury or death.
Do not take this control apart; it contains no 
replaceable components. Attempted disassembly 
or repair may damage the control.
Do not apply jumper across (or short) the 
valve coil terminals, even temporarily. Doing 
so may burn out the heat anticipator in the 
thermostat.
If Pilot Will Not light
1. Make sure 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.
3. If pilot will not light, check for:
a. closed pilot gas adjustment screw.
b. clogged pilot burner tubing or orifice.
c. gas leak at compression fitting.
If Pilot Goes Out When Reset 
Button Is Released
1. Make sure the reset button is held in at least one 
minute to allow the thermocouple time to heat.
2. Check pilot flame adjustment, see page 6.
3. Check the connection to the power unit. This is an 
electrical connection and must be clean and secure.
4. If pilot still goes out, use a millivoltmeter to measure 
the exact open circuit output voltages of the 
thermocouple. Compare to acceptable range charts 
in the thermocouple specifications. Replace the 
thermocouple if voltages are outside the acceptable 
range; otherwise, replace the gas control.
If Main Burner Will Not Come On 
With Call For Heat
1. Confirm that gas control knob is in the ON position.
2. Adjust thermostat several degrees above room 
temperature
3. Using ac voltmeter, measure voltage across 
thermostat 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.
INSTRUCTIONS TO THE 
HOMEOWNER
For Your Safety Read Before 
Lighting
Fire or Explosion Hazard can cause property 
damage, severe injury or death.
Before lighting, smell all around the appliance 
area for gas. If the appliance uses LP (bottled) 
gas, also be sure to smell next to the floor 
because LP gas is heavier than air. If you smell 
gas, immediately shut off the manual valve in the 
gas piping to the appliance, or, ON LP, AT THE 
TANK. Do not try to light any appliance. Don't 
touch any electrical switch or use the phone. 
LEAVE THE BUILDING and call your gas supplier.
