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.
