LX Series Direct Vent Gas Fireplace

Below Grade Installations

When it is not possible to meet the required vent terminal clearances of 12" above grade level, a snorkel kit is recom- mended. It allows installation depth down to 7" (178 mm) below grade level. The 7" (178 mm) is measured from the center of the horizontal vent pipe as it penetrates through the wall.

VENTING INSTALLATION

If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fasten brackets to wall first, then secure to snorkel with self drill- ing #8 x 1/2 sheet metal screws. It will be necessary to extend vent pipes out as far as the protruding wall face. Figure 26

Ensure that 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 area.

If installing a snorkel, a minimum 24" vertical rise is neces- sary. The maximum horizontal run with the 24” (610 mm) 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".

2.Remove soil to a depth of approximately 16" (406 mm) below base of snorkel. Install drain pipe. Install window well (not supplied). Refill hole with 12" (305 mm) of coarse gravel leaving a clearance of approximately 4" below snorkel. Figure 25

3.Install vent system.

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 pipes and secure to the wall.

7.Level the soil so as to maintain a 4" clearance below snorkel. Figure 25

vertical through-the-roof applica- tions

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. Figure 27

Install restrictor disk on vertical runs of 10' or more.

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

Example: Maximum horizontal length No elbows = 10’ (3 m)

1 x 45° elbows = 8.5’ (2.6 m)

2 x 45° elbows = 7’ (2.1 m)

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

Two sets of 45°elbows 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. Figure 28

The maximum angular variation allowed in the system is 270°. Figure 28
