11.12 - Sidewall
termination – Concentric
vent
11.12.1 - Description and usage
The termination kit must terminate outside the
structure and must be installed as shown in
Figure 11-19.
The required concentric termination kit as well as
combustion air and vent pipe materials are listed
in Figures 11-7 and 11-8.
The termination ending must be protected from
rain, see Figure 11-20.
11.12.2 - Sidewall termination
installation
1. Determine the best location for the termination
kit (see Figures 11-19 and 11-20).
2. The total length of piping for vent or air must
not exceed the limits given in Section 11-4.
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 Figures 11-19 and
11-20.
CAUTION!!!
DO NOT use fi eld-supplied
couplings to extend pipes. Airfl ow
restriction will occur and may cause
intermittent operation.
6. Operate the appliance one (1) heat cycle to
ensure combustion air and vent pipes are
properly connected to the concentric vent
termination connections.
