COMBUSTION FAN ASSEMBLY
Inspect the pressure switch and tubing connections and
inspect the fan assembly for warpage, deterioration and
debris or other build-up. Remove any debris from the fan
and motor assembly.
INSPECTING THE VENTING SYSTEM
The venting system should be inspected during the
annual maintenance check-up or during each
subsequent service call.
Check the vent system for restrictions due to soot, or
carbon build-up, as well as foreign matter, or any
materials, that cause the venting system to restrict the
proper venting of combustion products. If a restriction is
found, the roof jack
must
be cleaned or replaced to
ensure proper venting.
Vent pipes should also be inspected for any signs of
corrosion, deterioration, or leakage that may cause
combustion by-products to infiltrate the home or indoor
environment.
If signs of corrosion, deterioration, or leakage are
evident, the Roof Jack
must
be replaced with a properly
sized, agency-approved, Roof Jack.
.
GASKETS/SEALING MATERIALS
Inspect all visible gaskets for signs of degradation,
especially any seals which were removed as part of the
inspection. Replace any suspect gaskets.
HEAT EXCHANGER
Inspect for corrosion, pitting, warpage, deterioration,
carbon build-up, and loose gaskets in the flue pipe, and
accessible areas of the heat exchanger.
HOUSE AIR BLOWER
Check and clean the blower wheel, housing, and
compartment with a vacuum.
IMPORTANT:
The blower motor is permanently
lubricated
and should not be oiled.
