Operating Your Furnace - COZY DVCF402D Owner's Manual

OPERATING YOUR FURNACE

WARNING: Danger of bodily injury or death.
Liquefied petroleum L.P. Gas is heavier than air and it
will settle in any low area, including open depressions
and it will remain there unless the area is ventilated.
NOTE:
For models equipped with Cozy gas valve P322041 or
P322042 refer to this pages 20-21 for "SAFETY & LIGHTING
INSTRUCTION" and "TURN GAS OFF TO APPLIANCE."
For models equipped with Cozy gas valve P321704 or
P321705 refer to this page and Page 23 for "SAFETY &
LIGHTING INSTRUCTIONS" and "TURN GAS OFF TO
APPLIANCE.''
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 21) 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.

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 DVCF60XD.

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.
