LIGHTING THE FURNACE WITH A MATCH
If the spark ignitor fails to provide spark to light the pilot,
loosen the wing nut holding the peep hole cover. This will
open the peep hole into the heat exchanger and the pilot
can be ignited with a match.
1. Follow the instructions under "LIGHTING AND
OPERATING INSTRUCTIONS" and use a match to
light the pilot as instructed.
WARNING
DANGER OF IGNITION FLASH
AND EYE INJURY OR BLINDNESS
PROTECT YOUR EYES. NEVER ATTEMPT TO
LIGHT PILOT WITH GAS CONTROL VALVE
KNOB IN "ON" POSITION. FLASHBACK COULD
OCCUR.
2. After lighting the pilot, carefully replace the pilot
observation door (peep hole cover) and tighten wing
nut down.
On new installations the gas lineswill be filled withair and
it may take several tries to establish the pilot flame.
Check the manual shut-off valve in the gas line. It must
be in the open position (handle parallel to gas line) before
you can light your furnace.
Your furnace is equipped with a 100% safety pilot which
will shut off the gas valve in case the pilot is not burning
or functioning properly. Make sure the pilot is adjusted pro-
perly and that the thermocouple or generator connection
at the control valve is tight. If furnace will not stay lit, call
your local gas utility company.
Your furnace is equipped with a built-in pressure regulator.
L.R Gas models also have a regulator at the supply tank.
If you have a question regarding the amount of fuel
consumed, call your local gas utility or gas supplier. DO
NOT TAMPER WITH THE REGULATORS OR BURNER
ORIFICES, AS PROBLEMS RESULTING THEREFROM
