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 al-
low 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 bot-
toms 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 ta-
pered 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 VentPipesand Termination
NOTE: Combustion air intake and vent MUST terminate in the
same atmospheric pressure zone. If installation is in a cold cli-
mate (sustained temperatures below 0°F), increase the minimum
distance between vent pipe and air intake from 8" to 18".
CAUTION
Maintain a minimum of 36" 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.
Poison carbon monoxide gas hazard.
Inlet and outlet pipes may NOT be vented
directly above each other
Failure to properly vent this furnace can result in
death, personal injury and/or property damage.
Install all couplings, nipples and elbows using proper pro-
cedures for Joining Pipe and Fittings and maintain spac-
ing between vent and combustion air piping as indicated in
Figure 17 through Figure 25.

HorizontalTermination
Cut two holes. 21/2" for 2" pipe, 3" for 21/2" pipe, or 31/2" for
3" pipe. Do NOT make the holes oversized, or it will be nec-
essary 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 cou-
plings 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" to 1" and seal area between pipe and wall.
4. install the couplings, nipple and termination elbows as
shown and maintain spacing between vent and combus-
tion air piping as indicated in Figure 17 and Figure 18.
A metal shield is recommended 18" x 18" min. or 18" min. diame-
ter around the vent termination at the exterior wall to protect the
house exterior materials from flue product or condensation
(freezing) damage.
Using Exterior Risers
1. InstallelbowsandpipetoformriserasshowninFigure 18.
2. Secure vent pipe to wall with galvanized strap or other rust
resistant material to restrain pipe from moving.
3. insulate pipe with Armaflex or equivalent moisture resis-
tant closed cell foam insulation or Fiberglass insulation if
boxed in and sealed against moisture.
