Below Grade Installations

When it is not possible to meet the required vent termi- nal clearances of 12 inches (305mm) above grade level a model #7DVSKS vent kit is recommended. It allows installation depth of down to 7 inches (178mm) below grade level. The 7 inches is measured from the centre

If venting system is installed below ground, we recommend a window well with adequate and proper drainage.

Ensure sidewall venting clearances are observed.

The maximum horizontal run with 24" vertical rise is 36" (915mm) from the back of the fireplace to the face of the exterior wall. See vent graph (Fig. 21) for extended horizontal run if the vertical exceeds 24".

1.Establish vent hole through the wall. See page 14

2.Remove soil to a depth of approximately 16" below base of snorkel. Install window well (not supplied). Refill hole with 12" of coarse gravel leaving a clear- ance of approximately 4" below snorkel. (Fig. 30)

3.Install vent system. See page 15, Steps 2 through 5.

4.Ensure a watertight seal is made around the vent pipe coming through the wall.

5.Apply high temperature sealant caulking (supplied) around the 4 and 7 inch 7DVSKS's snorkel collars.

6.Slide into vent pipe and secure to the wall.

7.Level the soil so as to maintain a 4" clearance below snorkel (Fig. 30).

If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fasten brackets to wall first and then secure to snorkel with self drilling #8 x 1/2 sheet metal screws. It will be necessary to extend vent pipes out as far protruding wall face (Fig. 31).
