7. Level the soil to maintain a 4” (102 mm) clearance below snorkel. (Fig. 26) Do not back fill around snorkel. A clearance of at least 4” (102 mm) must be maintained between snorkel and the soil. When it is not possible to meet the required vent ter- minal clearances of 12” (305mm) above grade level a snorkel vent kit is recommended. It allows installation depth of down to 7” (178mm) below grade level. The 7” is measured from the center of the horizontal vent pipe as it penetrates through the wall.

(165mm) FP1475 Fig. 25 Bend flex vent at 90° so horizontal portion is 6...” (165 mm) off top of unit. If venting system is installed below ground, we recommend a window well with adequate and proper drainage. Ensure sidewall venting clearances are observed. FP1475 If installing a snorkel a minimum 24” (610 mm) vertical flex 90 bend rise is necessary. The maximum horizontal run with the 24” (610 mm) vertical pipe is 36” (914 mm). This 4/04 djt measurement is taken from the collar of the fireplace (or transition elbow) to the face of the exterior wall. Refer to the Sidewall Vent Graph for extended horizontal run if the vertical rise exceeds 24” (610 mm). Fig. 26 Below grade 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 drilling #8 x 1/2 sheet metal screws. It will be necessary to extend vent pipes out as far as protruding wall face.

Vertical Through-the-Roof Applications 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. 28) Max. 10' (3m) Max. Height40' (12m) Min. Height7......' (2.3m) Pipe Straps Every 3’ (914mm) FP1244 Fig. 28 Support straps for horizontal runs. • Up to two 45° elbows may be used within the horizontal run. For each 45° elbow used on the horizontal level the maximum horizontal length must be reduced by 18” (457 mm). Example: Maximum horizontal length 0 x 45° elbows = 10’ (3 m) 1 x 45° elbows = 8...’ (2.6 m) 2 x 45° elbows = 7’ (2.1 m) • A minimum of an 8’ (2.4 m) vertical rise. • Two sets of 45° elbows offsets within these vertical installations. From 0 to a maximum of 8’ (2.4 m) of vent pipe can be used between elbows. (Fig. 29) • 7DVCS must be used to support offsets. (Fig. 31) This application will require that you first determine the roof pitch and use the appropriate starter kit. (Refer to Venting Components List) • The minimum height of the vent above the highest point of penetration through the roof is 2’ (610 mm).

Locate your fireplace. 2. Plumb to center of the (4” (102 mm) flue collar from ceiling above and mark position. 3. Cut opening equal to 9...” x 9...” (240 x 240 mm). 4. Proceed to plumb for additional openings through the roof. In all cases, the opening must provide a minimum of 1” (25mm) clearance to the vent pipe, i.e., the hole must be at least 9...” x 9...” (240 x 240 mm). 5. Place fireplace into position. 6. Place firestop(s) #7DVFS or Attic Insulation Shield #7DVAIS into position and secure.

Install roof support (Fig. 31) and roof flashing making sure upper flange of flashing is below the shingles. (Fig. 32) 8. Install appropriate pipe sections until the venting is above the flashing. (Fig. 32) 9. Install storm collar and seal around the pipe. 10. Add additional vent lengths for proper height.
