Install Snorkel #7TDVSNORK when it is not possible
12/6/99 djt
to meet the required vent termination clearances of 12"
(305 mm) above grade level. The snorkel kit will allow
installation depth of down to 7" (178 mm) 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. 29)

1. Establish the vent hole through the wall.
2. Remove soil to a depth of approximately 16" (400
mm) below the base of the snorkel. Install a window
well (not supplied). Refill the hole with 12" (305 mm)
of coarse gravel and maintain a clearance of at least
4" (102 mm) below the snorkel. (Fig. 29)
3. Install the vent system as described on Pages 15-
18.
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.
6. Level the soil to maintain a 4" clearance below the
snorkel.
If the foundation is recessed, use extension brack-
ets (not supplied) to fasten the lower portion of the
snorkel. Fasten the brackets to the wall first, and
then fasten to the snorkel with self-tapping #8 x 1/2"
sheet metal screws. Extend the vent pipes out as far
as the protruding wall face. (Fig. 30)
