Horizontal Termination

1, 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 combustion air piping as indicated in Figure 20 and Figure 21.

A metal shield is recommended 18" x 18" min. or 18" min. diameter 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, Install elbows and pipe to form riser as shown in Figure 21.

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 resistant closed cell foam insulation or Fiberglass insulation if boxed in and sealed against moisture.

Vertical Termination

1.Figure 22 shows the proper installation and clearances for

vertical vent termination. The vertical roof termination should be sealed with a plumbing roof boot or equivalent flashing. The inlet of the intake pipe and end of the exhaust vent must be terminated no less than 12" above the roof or

snow accumulation level, and 12" away from a vertical wall or other protrusion.

2.If the vent system is installed in an existing chimney make

sure clearances shown in Figure 22 are maintained. Hori-

zontal section before the termination elbow can be ex- tended on the inlet air to provide necessary clearance.

Vent Termination Shielding

Under certain wind conditions some building materials may be af- fected by flue products expelled in close proximity to unprotected surfaces. Sealing or shielding of the exposed surfaces with a cor- rosion resistant material (such as aluminum sheeting) may be re-

quired to prevent staining or deterioration. The protective material should be attached and sealed (if necessary) to the building before attaching the vent terminal.
