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 electronic module.
IMPORTANT
Allow 60 seconds after shutdown before re-
energizing the step-opening module to ensure
lightoff at steppressure.
IF MAIN BURNER WILL NOT COME ON WITH CALL
FOR HEAT
1. Ensure the gas control knob is in the ON position.
2. Adjust the thermostat several degrees above room
temperature.
3. Using an AC voltmeter, check for 24V at gas
control.
• If pilot lights, measure across MV/PV and MV.
• If pilot does not light, measure across MV/PV
and PV before safety lockout occurs.
4. If voltage is incorrect or not present, check control
circuit for proper operation.
5. If 24V is present, replace the gas control.
INSTRUCTIONS TO THE
HOMEOWNER
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 the pilot burner flame, smell around
the appliance for gas. Be sure to smell close to the
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. Do not force the gas control knob. Use only your
hand to push down or turn the gas control knob.
Never use tools. If the gas control knob will not
operate by hand, the gas control should be
replaced by a qualified service technician. Force or
attempted repair may result in a fire or explosion.
5. The gas control must be replaced in case of any
physical damage, tampering, bent terminals, miss-
ing or broken parts, stripped threads, or evidence
of exposure to heat.
IMPORTANT
Follow the operating instructions provided by
the manufacturer of your heating appliance. The
information below will be of assistance in a typi-
cal gas control application, but the specific con-
trols used and the procedures outlined by the
