Fig. 21 -- Proper Sealing Procedure for Combustion Blower

Joining Pipe and Fittings

SEE VENT AND COMBUSTION AIR PIPING, Vent and

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 checking 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 excess 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 inlet and clothes dryer vent. Terminate

the combustion 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

shown and maintain spacing between vent and combustion

A metal shield is recommended 18″ x 18″ (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.
