STEP 7

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

STEP 8

Recheck the fireplace to make sure that it is levelled, properly positioned, and nailed or screwed to the floor.

BELOW GRADE INSTALLATIONS

When it is not possible to meet the required vent terminal clearances of 12 inches (305mm) above grade level a model 7TDVSKS vent kit is required. It allows installation depth of down to 7 inches (178mm) below grade level. The 7 inches is measured from the centre of the horizontal 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" (610mm) vertical rise is 36" (914mm) from the back of the fireplace to the face of the exterior wall. See vent graph (Fig. 36) for extended horizontal run if the vertical exceeds 24" (610mm).

1.Establish vent hole through the wall. See page 19

2.Remove soil to a depth of approximately 16" (406mm) below base of snorkel. Install window well (not supplied). Refill hole with 12" (305mm) of coarse gravel leaving a clearance of approximately 4" (100mm)below snorkel. (Fig. 47)

3.Install vent system. See page 19/20, 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 7TDVSKS's snorkel collars.

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

7.Level the soil so as to maintain a 4" (100mm)clearance below snorkel (Fig. 47).

If applied, the fireplaces adjustable frame drywall strips (nailing flanges) should be fastened. See "Framing & Finishing.
