TWIN PIPE VENTING GUIDE
Installation:
1) Once location is determined, cut two (2) appropriately sized
holes in the wall to accommodate the pipe. (Reference the
following Low Profile Termination Kit Dimensions table)
Vers l'entrée d'air
2) Slide intake and exhaust pipes through the holes. Secure (us-
du chauffe-eau
ing solvent cement) both pipes to the base of the vent termi-
nation kit. (Be sure to follow guidelines for solvent cementing

All exhaust vents and air inlets must terminate at the same height
to avoid substantial property damage, personal injury, or death.

Twin Pipe (PVC/CPVC) Terminations

Évent
PVC/CPVC Sidewall (Tee and Snorkel) Terminations:
Locate the vent and intake air termination using the following
guidelines:
1) The total length of the vent or intake air piping must not ex-
ceed the limits given in Tables 11-14. The equivalent length
for 90° elbows and termination associated with the respective
vent and intake air piping arrangement MUST be subtracted
from total length listed in Tables 11-14.
2) Specific to Side Wall Tee Termination, the vent and intake air
piping must terminate at the outside surface of the outer wall,
minimum one (1) inch (2.5 cm) between wall, tee, and elbow
socket ends (see Figure 24).
3) Termination must be installed twelve (12) inches (30.5 cm),
above the highest anticipated snow level (see Figures 25 & 26).

4) Refer to Table 3 this document for recommendation on vent/
d'air / échappement
combustion air intake terminal position.
NOTE: If the vent is terminated on a sidewall which is subject
to high winds it is recommended to terminate the vent using a
tee. A tee provides the best protection against wind.
5) The intake air pipe must terminate using a 90° elbow directed
away from the vent termination. Both vent and air intake pipe
terminations must be installed twelve (12) inches (30.5 cm)
minimum above grade or highest anticipated snow level and
as shown in Figures 25 and 26.
