Below Grade Installations

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

Ensure the sidewall venting clearances are observed. If venting system is installed below ground, we recom- mend a window well with adequate and proper drainage to be installed around the termination.

If installing a snorkel, a minimum 24” (610 mm) vertical rise is necessary. The maximum horizontal run with the 24” vertical pipe is 36” (914 mm). This measurement is taken from the collar of the fireplace (or transition elbow) to the face of the exterior wall. See the Sidewall Venting Graph for extended horizontal run if the vertical exceeds 24” (610 mm).

1.Establish vent hole through the wall. (Fig. 33)

2.Remove soil to a depth of approximately 16”

(406 mm) 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. 39)

3.Install vent system. See Page 18, 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” snorkel collars.

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

7.Level the soil to maintain a 4” (102 mm) clearance below snorkel. (Fig. 39)

Do not backfill around snorkel.

A clearance of at lest 4” must be main- tained between the snorkel and the soil.

If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fas- ten brackets to wall first, 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 as the protruding wall face. (Fig. 40)

Vertical Through-the-Roof Application

This gas fireplace has been approved for:

Vertical installations up to 40’ (12 m) in height. Up to a 10’ (3 m) horizontal vent run can be installed within the vent system using a maximum of two 90° elbows. (Fig. 41)

Up to two 45° elbows may be used within the hori- zontal run. For each 45° elbow used on the horizon- tal plane, the maximum horizontal length must be reduced by 18” (450 mm).

Example: Maximum horizontal length:

*A minimum of 24” (610 mm) vertical pipe must be installed when using the 7TDVSNORK.

2 x 45° elbows = 7’ (2.1 m)

A minimum of an 8’ (2.5m) vertical rise is required.

Two sets of 45° elbow offsets may be used within the

vertical sections. From 0 to a maximum of 8’ (2.5 m)

of vent pipe can be used between elbows. (Fig. 42)

7DVCS supports offsets. (Fig. 44) This application

will require that you first determine the roof pitch

and use the appropriate starter kit. (Refer to Venting

Components List)

The maximum angular variation allowed in the sys-

tem is 270°. (Fig. 42)

The minimum height of the vent above the highest
