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/main burner flame is lit automatically. Do
not light the pilot/main burner flame manually.
2. Before lighting appliance, smell around the ap-
pliance for gas. Be sure to smell next 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 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 any tools. If the gas control knob will
not operate by hand, call a qualified service
technician to replace the gas control. Force or
attempted repair can result in a fire or explosion.
5. Call a qualified service technician to replace the
gas control if it has been flooded with water.
6. Replace the gas control in the event of any
physical damage, tampering, bent terminals,
missing or broken parts, stripped threads, or
evidence of exposure to heat.
3. Using an ac voltmeter, check for voltage at the gas
control.
• Intermittent Pilot Igntion—If pilot lights, measure
voltage across MV/PV and MV. If pilot does not light,
measure across MV/PV and PV before safety lockout
occurs.
• Hot Surface or Direct Spark Ignition—Measure volt-
age across MV terminals at gas control.
4. If voltage is not present, check control circuit for pro-
per operation.
5. If proper control circuit voltage is present, replace gas
control.
IMPORTANT: Follow the operating instructions provided
by the manufacturer of your heating appliance. The
information below will be helpful in a typical gas
control application, but the specific controls used and
the procedures outlined by the manufacturer or your
appliance may differ and require special instructions.
