WARNING!!!
The air
inlet pipe(s) must be sealed.
Improper sealed can result
in excessive levels of carbon
monoxide which can result
in severe personal injury or
death!
Choose acceptable combustion air
inlet pipe materials from the following
list:
- PVC, CPVC.
- AL29-4C, stainless steel material
to be sealed to specification of its
manufacturer.
- Polypropylene material to be sealed
to specification of its manufacturer.
WARNING!!!
Using air
intake materials other than
those specified, mixing the
specified materials, failure to
properly seal all seams and
joints or failure to follow the
manufacturer's instructions
can result in flue gas
recirculation, spillage of flue
products and carbon monoxide
emissions causing severe
personal injury or death.

NOTICE! Polypropylene and stainless
steel pipe may require an adapter (not
provided) to transition between the air
inlet connection on the appliance and
the air inlet pipe.
NOTICE! The use of insulated
material for the combustion air
inlet pipe is recommended in cold
climates to prevent the condensation
of airborne moisture in the incoming
combustion air.
NOTICE! Combustion air piping must
be supported per guidelines listed
in the "National Mechanical code",
section 305, table 305.4 or local
codes dictate.
11.5.1 - Sealing of PVC or
CPVC air inlet pipe
The PVC or CPVC air inlet pipe
should be cleaned and sealed
with the pipe manufacturer's
recommended solvents and standard
commercial pipe cement for the
material used. The PVC or CPVC
air inlet pipe should use a silicone
sealant MOMENTIVE - RTV 106, to
ensure a proper seal at the appliance
connection and the air inlet cap
connection. Proper sealing of the air
inlet pipe ensures that combustion
air will be free of contaminants and
supplied in proper volume.

disconnected for any reason, the air
inlet pipe must be resealed to ensure
that combustion air will be free of
contaminants and supplied in proper
volume.
WARNING!!!
properly seal all joints and
seams as required in the air
inlet piping may result in flue
gas recirculation, spillage
of flue products and carbon
monoxide emissions causing
severe personal injury or
death.
WARNING!!!
pipes must be glued, properly
supported and pitched a
minimum of a 1/4 inch per foot
out to the appliance (to allow
drainage of water into the
appliance). Failure to follow
this warning could result in
excessive levels of carbon
monoxide or a fire, which can
result in severe personal injury
or death!
