Horizontal length requirement.

 

STEP 6

Support the horizontal pipes every 36” (914 mm) with metal pipe straps. Make sure that the horizontal vent pipe is installed on a level horizontal plane.

STEP 7

Re-check the fireplace to make sure that it is levelled, properly positioned, and nailed or screwed to the floor. If applied, the fireplaces adjustable frame drywall strips (nailing flanges) should be fastened. Refer to “Framing & Finishing”.

When it is not possible to meet the required vent ter- minal clearances of 12” (305 mm) above grade level a snorkel vent kit #7TDVSNORK is required. It allows installation depth of down to 7” (178 mm) below grade level. The 7” is measured from the center of the hori- zontal vent pipe as it penetrates through the wall.

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” (914 mm) from the back of the fireplace to the face of the exterior wall. See vent graph (Page 13) for extended horizontal run if the vertical rise exceeds 24” (610 mm).

1.Establish vent hole through the wall. (Fig. 17)

2.Remove soil to a depth of approximately 16” (406mm) below base of snorkel. Install window well (not supplied). Refill hole with 12” (305 mm) of coarse gravel leaving a clearance of approximately 4” (102 mm) below snorkel. (Fig. 34)

3.Install vent system. See Page 14, 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 around the 4” and 7” snorkel collars.

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

7.Level the soil to maintain a 4” (102 mm) clearance below snorkel. (Fig. 34)
