!WARNING
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.
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
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
!WARNING
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.
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.

1.Cut two holes. 21/2″ (63.5mm) for 2″ (50.mm) pipe, 3″ (76.2mm) for 21/2″ (63.5mm) pipe, or 31/2″ (88.9mm) for 3″
(76.2mm) pipe. Do NOT make the holes oversized, or it will be necessary to add a sheet metal or plywood plate on the outside with the correct size hole in it.
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.
3.Extend vent pipe and combustion air pipe through the wall 3/4″ (19.1mm) to 1″ (25.4mm) and seal area between pipe and wall.
4.Install the couplings, nipple and termination elbows as shown and maintain spacing between vent and combustion air piping as indicated in Fig. 22 and Fig. 23.
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.
