ignition sequence up to two times after the sensor cools. If
ignition is not achieved, it will lockout the furnace.
3.
POWER FAILURE
If there is a power failure during a heating cycle, the system
will restart the ignition sequence automatically when power
is restored, if the thermostat still calls for heat.
4.
INDUCED DRAFT BLOWER FAILURE
If pressure is not sensed by the pressure switch, it will not
allow the gas valve to open, therefore the unit will not start.
If failure occurs during a running cycle, the pressure switch
will cause the gas valve to close and shut the unit down.
Failure to follow safety warnings exactly, could
result in a fire or explosion causing property
damage, personal injury or loss of life.

WARNING
!
The following warning complies with State of California law, Proposition 65.
This product contains fiberglass wool insulation!
Fiberglass dust and ceramic fibers are believed by
the State of California to cause cancer through
inhalation. Glasswool fibers may also cause
respiratory, skin, or eye irritation.
PRECAUTIONARY MEASURES
●
Avoid breathing fiberglass dust.
●
Use a NIOSH approved dust/mist respirator.
●
Avoid contact with the skin or eyes. Wear long-
sleeved,
loose-fitting clothing, gloves, and eye protection.
●
Wash clothes separately from other clothing: rinse
washer thoroughly.
●
Operations such as sawing, blowing, tear-out, and
spraying may generate fiber concentrations
requiring
additional respiratory protection. Use the
appropriate
NIOSH approved respirator in these situations.
FIRST AID MEASURES
Eye Contact –
Flush eyes with water to remove dust.
If symptoms persist, seek medical
attention.
Skin Contact –
Wash affected areas gently with soap
and warm water after handling.
