Fig. 21 -- Proper Sealing Procedure for Combustion Blower

SEE VENT AND COMBUSTION AIR PIPING, Vent a nd
Combustion Air Piping Guidelines in this manual for applicable
ASTM Standards for vent materials.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
Do NOT use solvent cement that has become curdled, lumpy
or thickened and do NOT thin. Observe precautions printed
on containers. For applications below 32_F(0_C), use only
low temperature type solvent cement. Poor joints may lead to
disconnected or leaking vent pipe joints allowing carbon
monoxide to enter the living space.
!
WARNING
1. Cut pipe end square, remove ragged edges and burrs.
Chamfer end of pipe, then clean fitting, socket and pipe joint
of all dirt, grease, or moisture.
NOTE: Stir the solvent cement frequently while using. Use a
natural bristle brush or the dauber supplied with the cement. The
proper brush size is one inch.
2. After c hecking pipe and socket for proper fit, wipe socket
and pipe with cleaner-primer. Apply a liberal coat of primer
to inside surface of socket and outside of pipe. Do NOT
allow primer to dry before applying cement.
3. Apply a thin coat of cement evenly in the socket. Quickly
apply a heavy coat of cement to the pipe end and insert pipe
into fittings with a slight twisting movement until it bottoms
out.
NOTE: Cement MUST be fluid while inserting pipe. If NOT,
recoat pipe.
4. Hold the pipe in the fitting for 30 seconds to prevent the
tapered socket from pushing the pipe out of the fitting.
5. Wipe all e xcess cement from the joint with a rag. Allow 15
minutes before handling. Cure time varies according to fit,
temperature and humidity.
Connecting Vent Pipes and Termination
NOTE: Combustion air intake and vent MUST terminate in the
same atmospheric pressure zone. If installation is in a cold climate
(sustained temperatures 0°F(--17°C) and below for 24 or more
consecutive hours), increase the minimum distance between vent
pipe and air intake from 8″ (203.2mm) to 18″(457.2mm).
CARBON MONOXIDE POISONING HAZARD
Failure to properly vent this furnace could result in personal
injury or death.
Maintain a minimum of 36″ (914.4mm) between
combustion air inl et and clothes dryer vent. Terminate
the com bustion air intake as far as possible from any
air conditioner, heat pump, swimming pool,
swimming pool pumping, chlorinator or filtration unit.

WARNING
1. Install all couplings, nipples and elbows using proper
procedures for Joining Pipe and Fittings and maintain
spacing between vent and combustion air piping as indicated
in Fig. 22through 30.

2. Check hole sizes by making sure it is smaller than the
couplings or elbows that will be installed on the outside. The
couplings or elbows MUST prevent the pipe from being
pushed back through the wall.

4. Install the couplings, nipple and termination elbows as

A metal shield is recommended 18″ x18″ (457.2mm x 457.2mm)
min. or 18″ (457.2mm) min. diameter around the vent termination
at the exterior wall to protect the house exterior materials from flue
product or condensation (freezing) damage.
