Do noT touch igniter. It is extremely hot.
1. GENERAL INSPECTION – Examine the furnace in-
stallation for the following items:
a. All flue product carrying areas external to the fur-
nace (i.e. chimney, vent connector) are clear and free
of obstruction.
b. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corro-
sion.
c. The return air duct connection(s) is physically
sound, is sealed to the furnace and terminates out-
side the space containing the furnace.
d. The physical support of the furnace should be sound
without sagging, cracks, gaps, etc., around the base
so as to provide a seal between the support and the
base.
e. There are no obvious signs of deterioration of the
furnace.
2. BLOWERS – The blower size and speed determine the
air volume delivered by the furnace. The blower mo-
tor bearings are factory lubricated and under normal
operating conditions usually do not require servicing.
Annual cleaning of the blower wheel and housing is
recommended for maximum air output, and this must
be performed only by a qualified servicer or service
agency.
3. IGNITER – This unit has a special hot surface direct
ignition device that automatically lights the burners.
Please note that it is very fragile and should be han-
dled with care.
4. BURNER – Gas burners do not normally require
scheduled servicing, however, accumulation of foreign
material may cause a yellowing flame or delayed igni-
tion. Either condition indicates that a service call is
required. For best operation, burners must be cleaned
annually using brushes and vacuum cleaner.
Turn off gas and electric power supply. To clean burners,
remove top burner bracket and lift burner from orifice.
NOTE: Be careful NOT to break igniter when removing
burners.
Clean burners with brush and/or vacuum cleaner. Reas-
semble parts by reversal of the above procedure.
NOTE: On LP (propane) units, some light yellow tipping of
the outer mantle is normal. Inner mantle should be bright
blue.
Natural gas units should not have any yellow tipped flames.
This condition indicates that a service call is required. For
best operation, burners must be cleaned annually using
brushes and vacuum cleaner.
The following warning complies with State of California law, Proposition 65.
