pressure.
IF PILOT WILL NOT LIGHT
1. 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”, page 4. If pilot still will not light:
a. Check pilot gas adjustment screw. If closed, read-
just pilot flame. Refer to page 4.
b. Perform gas leak test at compression fitting. If leak
is detected, replace old compression fitting or tighten new
one. Refer to page 3.
c. Ensure that pilot burner tubing or orifice is not
clogged. If clogged, replace combination gas control.
IF PILOT GOES OUT WHEN GAS CONTROL KNOB IS
RELEASED
1. 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 page 4.
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.
CAUTION
IMPORTANT
6. Check power unit resistance. If above 11 ohms,
replace gas control.
IF MAIN BURNER WILL NOT COME ON WITH CALL
FOR HEAT
1. Make sure gas control knob is in the ON position.
2. Adjust thermostat several degrees above room tem-
perature.
3. Disconnect leadwires to lower left TH terminal and
lower right PP terminal to isolate valve operator coil from
