Examine the heat exchanger,
vent pipe, combustion
air passages,
vent connectors
and chimney to be sure they are clear and free of
obstructions.
2.
Examine
the vent pipe making
sure it is firmly
in place, that it
slopes slightly upward and is physically
sound without
holes and
all of the connections
are secure.
3.
Examine return connections
For Modular Homes:
a.
If the fumace
has a return air duct, examine
the return air
duct connections
to make sure they are physically
sound,
sealed to the furnace
casing, and the ducts terminate
out-
side the space containing
the furnace.
b.
If the furnace does not have a return air duct, examine the
return air filter rack connections
to make sure they are phys-
ically sound, sealed to the furnace casing.
For Manufactured
(Mobile) Homes:
a.
Examine
the return air filter rack connections
to make sure
they are physically
sound, sealed to the furnace casing.
4.
Examine
the furnace
casing making
sure the physical
support
is
sound without sagging, cracks or gaps. Examine the furnace base
making sure it is physically
sound without cracks, gaps or sagging
and has a good seal.
5.
Examine the furnace casing for obvious signs of deterioration.
6.
