PERIODIC INSPECTION PROCEDURES
GAS HEATING UNITS
1.
The flow of combustion and ventilating cannot
be obstructed in any way. The indoor blower, evaporator
coil and filters must be inspected monthly.
2. Once each year, prior to the heating season, a
qualified technician must inspect all flue product carry-
ing areas of the furnace and main burners for continued
safe operation.
WARNING: At least once each year, a qualified ser-
vice technician should check out all of the items listed
under the servicing and trouble shooting and mainte-
nance section of this manual.
3. If the induced draft blower/motor assembly re-
quires replacement, an airtight seal between the blower
housing and the burner box must be restored. High
temperature silicone sealant must be used to ensure a
good seal.
4. GAS BURNERS
THE BURNERS SHOULD NEVER REQUIRE
CLEANING.
If cleaning is necessary, it indicates faulty operation of
the unit. The cleaning should be done only by a qualified
service agency after consultation with an AAON Service
Representative.
It is recommended that if the gas burners require cleaning,
call an AAON Service Engineer at (918) 583-2266.
5. HEAT EXCHANGER
The necessity for cleaning the exchanger could indicate
faulty operation and should only be checked by a quali-
fied service agency after they have discussed the prob-
lem with a Service Representative.
