STANDING PILOT MODELS
4007732; 6007732; 4007731; 6007731
NOTE:
For models equipped with WILLIAMS gas valve P322041 or
P322042 refer to this page and Page 23 for "SAFETY &
LIGHTING INSTRUCTION" and "TURN GAS OFF TO
APPLIANCE."
For models equipped with WILLIAMS gas valve P321704 or
P321705 refer to this page and Page 24 for "SAFETY &
LIGHTING INSTRUCTIONS" and "TURN GAS OFF TO
APPLIANCE.''
(All other models refer to page 25, 26 & 27.)
These furnaces are equipped with a manually operated Piezo
spark igniter device to ignite the pilot gas. Follow the steps under
"Lighting Instructions" (see Page 23 or Page 24) and use the
manual spark igniter to light the pilot in Step 10. Press spark
igniter button vigorously and repeatedly.
On new installations, the gas lines will be filled with air and it may
take several minutes to establish the pilot flame.
Keep all access doors and panels in place except for inspection
and maintenance.
WARNING: The surface of the furnace is hot during
operation. Keep children, clothing, furniture, and
flammable material away from it.
Do not store or use gasoline or other flammable
liquids or vapors near the furnace.
SAFETY CONTROLS
These furnace are protected against unsafe operation by four
automatic safety controls: (1) A safety pilot acts to shut OFF the
gas valve in case of pilot failure; (2) A redundant gas valve; (3) A
limit switch shuts down the main burner to prevent overheating
the furnace cabinet; this limit switch wilt reset when furnace cools;
and (4) A thermal overload protects the motor against burnout
caused by current surges or if anything should block the flow of air
through the furnace. This switch will reset itself when the motor
cools down and it cannot be adjusted.
WARNING: Danger of bodily injury or death.
Do not operate the furnace with a broken or
missing pilot observation door.
For models equipped with WILLIAMS gas valve P321704 or
P321705.
Models are equipped with a two-rate control valve. The rate knob
on the gas valve is marked "LO" and "HI." Turn the rate knob to
the "LO" position and the room thermostat will operate the main
burner at about 70% of maximum capacity. Turn the rate knob to
the "HI" position only when a fast heat-up is desired during
extremely cold weather. High operation develops maximum
capacity of the furnace.
A two-speed fan is used with Models 6007732 and 6007731.
Blower will operate at low speed then shift to high speed as the
furnace heats up.
WARNING: Danger of property damage. Bodily
injury or death
If the furnace overheats or fails to shut off, turn off
the manual gas valve to the furnace before turning
off the electric power.
