Vent Termination Below Grade

Install Snorkel #7TDVSNORK when it is not possible to meet the required vent termination clearances of 12”

NOTE: Be sure to maintain side wall clearances and vent run restrictions. Refer to Figures 3 through 11.

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)

(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)
