8.10.3 - Prepare wall
penetrations
1. Air pipe penetration:
a. Cut a hole for the air pipe. Size the air
pipe hole as close as desired to the air
pipe outside diameter.
2. Vent pipe penetration:
a. Cut a hole for the vent pipe. For
either combustible or noncombustible
construction, size the vent pipe hole with
at least a 1/2 inch clearance around the
vent pipe outer diameter (4½ inch hole
for 3 inch vent pipe)
b. Insert a galvanized metal thimble in the
vent pipe hole as shown in Figure 33.
3. Use a sidewall termination plate as a
template for correct location of hole
centers.
4. Follow all local codes for isolation of vent
pipe when passing through fl oors or walls.
5. Seal exterior openings thoroughly with
exterior caulk.
8.10.4 - Termination and
fi ttings
1. The air termination coupling must be
oriented at least 12 inches above grade or
snow line as shown in Figures 31 and 32.
2. Maintain the required dimensions of the
fi nished termination piping as shown in
Figures 31 and 32.
3. Do not extend exposed vent pipe outside
of the building more than what is shown
in Figures 31 and 32. Condensate could
freeze and block vent pipe.
8.10.5 - Multiple vent/air
terminations
1. When terminating multiple boilers terminate
each vent/air connection as shown in
Figure 34.
WARNING!!! All vent pipes and air
inlets must terminate at the same height to
avoid possibility of severe personal injury,
death, or substantial property damage.
2. Place wall penetrations to obtain minimum
clearance of 12 inches between edge of
air inlet and adjacent vent outlet, as shown
in Figure 34 for U.S. installations. For
Canadian installations, provide clearances
required by CSA B149.1 Installation Code.
3. The air inlet is part of a direct vent
connection. It is not classifi ed as a forced
air intake with regard to spacing from
adjacent boiler vents.
