PERIODIC INSPECTION PROCEDURES
GAS HEATING UNITS
1.
The flow of combustion and ventilating air shall
not be blocked or otherwise obstructed in any way.
The indoor blower, evaporator coil and filters should be
inspected monthly.
2. Once each year, before unit is turned on for the
heating season, a qualified serviceman should inspect
all flue product carrying areas of the furnace and main
burners for continued safe operation.
WARNING: At least once each year, a qualified ser-
viceman should check out all of the items listed under
the servicing and trouble shooting and maintenance
section of this manual.
3. If the induced draft blower/motor assembly has
to be replaced, care must be taken to provide an air-
tight seal between the blower housing and the burner
box. High temperature silicone sealant must be used to
ensure a good seal.
4. GAS BURNERS
THE BURNERS SHOULD NEVER REQUIRE CLEAN-
ING. If cleaning becomes necessary, it indicates faulty
operation of the unit. The cleaning should only be done
by a qualified service agency and only 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 and only after they have discussed
the problem with a Service Representative.
