distance required if installing a second 90
°
elbow.
(Fig. 27)
8. Slip the wall plate and trim collar over the interior
end of the horizontal pipe and install into the wall
sleeve. Seal the joint inside the wall plate if needed
to keep cold air from being drawn into the home.
9. Connect the horizontal pipe to the elbow. Fasten the
wall plate to the pipe with three sheet metal screws.
Slide the trim collar up against the wall plate to cover
the screws. (Fig. 28)
10.Install the vent terminal. (Fig. 29) Guide the inner
and outer vent termination collars into the adjacent
pipes. Double check that the vent pipes overlap the
collars by 2”. Fasten the termination to the wall with
the screws provided, and caulk the joint with weath-
erproof sealant.
11.Install Charcoal Gray Pipe Rings (#7FSDRG) or
Polished Brass Pipe Rings (#7FSDRP) at pipe
joints, if desired.

Vent Termination Below Grade
Install Snorkel #7TDVSNORK when it is not possible to
meet the required vent termination clearances of 12”
(305mm) above grade level. The snorkel kit will allow
installation depth of down to 7” (178mm) below grade
level. The seven inches is measured from the center of
the horizontal vent pipe as it penetrates the wall. If the
venting system is installed below grade, a window
well must be installed with adequate and proper
drainage. (Fig. 30)
NOTE: Be sure to maintain side wall clearances and
vent run restrictions. Refer to Figures 3 through 9.
1. Establish the vent hole through the wall.
2. Remove soil to a depth of approximately 16”
(400mm) below the base of the snorkel. Install a
window well (not supplied). Refill the hole with 12”
(305mm) of coarse gravel and maintain a clearance
of at least 4” (102mm) below the snorkel. (Fig. 30)
3. Install the vent system as described on Pages 14-
17.
4. Be sure to make a watertight joint around the vent
pipe joint at the inside and outside wall joints.
5. Apply high temperature sealant around the inner and
outer snorkel collars. Join the pipes and fasten the
snorkel termination to the wall with the screws
provided.
