3. IGNITER - This unit has a special hot surface di-
rect ignition device that automatically lights the
burners. Please note that it is very fragile and
should be handled with care.
4. BURNER - Gas burners do not normally require
scheduled servicing, however, accumulation of for-
eign material may cause a yellowing flame or de-
layed ignition. Either condition indicates that a set-
vice 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 burn-
ers, remove top burner bracket and lift burner from ori-
flee.
NOTE: Be careful NOT to break igniter when removing
burners.
Clean burners with brush and/or vacuum cleaner. Re-
assemble parts by reversal of the above procedure.
NOTE: On LP (propane) units, some light yellow tip-
ping 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, burn-
ers must be cleaned annually using brushes and
vacuum cleaner.
NOTE: On LP (propane) units, due to variations in BTU
content and altitude, servicing may be required at
shorter intervals.
5. HEAT EXCHANGER/FLUE PIPE - These items
must be inspected for signs of corrosion, and/or de-
terioration at the beginning of each heating season
by a qualified service technician and cleaned annually
for best operation.
6. CIRCUIT PROTECTION - If blower or gas valve
fail to operate, the cause could be the circuit
breaker or a loose or blown fuse. Replace fuse or re-
set circuit breaker.
7. OPERATION - Your warm air furnace should not
be operated in a corrosive atmosphere. Paint sol-
vents, cleaning chemicals, spray propellants, and
bleaches should not be used in the vicinity of the
furnace during normal operation.
8. CONDENSATE DRAINS - If you have a cooling coil
installed with your furnace, condensate drains
should be checked and cleaned periodically to as-
sure that condensate can drain freely from coil to
drain. If condensate cannot drain freely water dam-
age could occur. Furnace drain should also be
checked & cleaned at the start of each heating sea-
son.
9. AIR CIRCULATION - To ensure increased comfort,
the blower on this unit may be operated continu-
ously for both heating and cooling. This will result
in constantly filtered air and aid in maintaining
more even temperatures by avoiding temperature
stratification throughout the conditioned area. To
accomplish constant air circulation, set your com-
fort control fan selector to "ON". Continuous fan
mode during COOLING operation may not be ap-
propriate in humid climates. If the indoor air ex-
ceeds 60% relative humidity or simply feels uncom-
fortably humid, it is recommended that the fan only
be used in the "AUTO" mode."
