Fig. 34 Measure the horizontal length.
(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” (100mm) below the snorkel. (Fig. 37)
3. Install the vent system as described on pages 19-21.
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 brackets
(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. 38)
Vent Termination Below Grade
Install Snorkel Kit #7FSDVSKS 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. 37)
NOTE: Be sure to maintain side wall clearances and
vent run restrictions. Refer to Figures 3-4 and 12-13.
1. Establish the vent hole through the wall.
2. Remove soil to a depth of approximately 16”
