10.12 - Sidewall
termination –
Concentric vent
10.12.1 - Description and
usage
The termination kit must terminate
outside the structure and must be
installed as shown in Figure 10-21.
The required concentric termination
kit as well as combustion air and vent
pipe materials are listed in Tables
10-1 and 10-2.
10.12.2 - Sidewall
termination installation
1. Determine the best location for the
termination kit (see Figure 10-21).
2. The total length of piping for vent or
air must not exceed the limits given
in Section 10-4.
3. You must consider the surroundings
when terminating the vent and air:
a. Position the vent termination
where vapors will not damage
nearby shrubs, plants or air
conditioning equipment or be
objectionable.
b. The fl ue products will form
a noticeable plume as they
condense in cold air. Avoid areas
where the plume could obstruct
window views.
c. Prevailing winds could cause
freezing of condensate and
water/ice buildup where fl ue
products impinge on building
surfaces or plants.
d. Avoid possibility of accidental
contact of fl ue products with
people or animals
e. Do not terminate above any door
or window. Condensate can
freeze, causing ice formations.
f. Locate or guard vent to prevent
condensate damage to exterior
fi nishes.
4. Cut one (1) hole 5 inch diameter
into the structure to install the
termination kit.
5. Install the Concentric vent kit
following the concentric kit
manufacturer’s instruction.
NOTICE Ensure termination location
clearance dimensions are as shown in
Figure 10-21.
