See sidewall vent graph, Page 15, for extended horizontal runs if the vertical exceeds 24” (610 mm). 1. Establish vent hole through the wall. (Fig. 24) 2. Remove soil to depth of about 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 about 4” (102 mm) below snorkel. (Fig. 28) 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 4 in. and 7 in. snorkel collars. 6. Slide snorkel into vent pipes and secure to wall. 7. Level the soil so as to maintain a 4” (102 mm) clearance below snorkel.

FP1442 Fig. 28 Below grade installation. Do not backfill around the snorkel. A clearance of at least 4” (102mm) must be maintained between the snorkel and the soil. 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 sheetmetal screws. It will be necessary to extend vent pipes out as far as protruding wall face.

Up to a 10’ (3 m) horizontal vent run can be installed within the vent system using a maximum of two 90° elbows. (Fig. 30) Max. Height 40’ (12.2m) Min. Height 8’ (2.4m) Max. 10’ (3m) Support Straps Every 36” (914mm) Max. 10’ (3m) Max. Height 40’ (12.2m) Min. Height 8’ (2.4m) FP1443 Fig. 30 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: Zero 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 ft. (2.43 m) vertical rise. • Two (2) sets of 45° elbow offsets may be used within the vertical sections. From zero to max 8 ft. (2.43 m) vent pipe can be used between elbows. (Fig. 30) • 7DVCS supports offsets. (Fig. 33) This application will require you first determine the roof pitch and use the appropriate starter kit. See Venting Components List, Page 22. • The maximum angular variation allowed in the system is 270.. (Fig. 31) • The minimum height of the vent above the highest point of penetration through the roof is 2’ (610mm). (Fig. 32) 123412341 + 2 + 3 + 4 = 270° FP1444 Fig. 31 Maximum elbow usage.

Plumb to center of the (4”) flue collar from ceiling above and mark position. 3. Cut an opening equal to 9...” x 9...” (240 x 240mm). 4. Proceed to plumb for additional openings through the roof. In all cases, the opening must provide a minimum of 1” (25 mm) clearance to the vent pipe, i.e., the hole must be at least 9...” x 9...” (240 x 240mm). 5. Place fireplace into position. 6. Place firestop(s) #7DVFS or Attic Insulation Shield #7DVAIS into position and secure. (Fig. 35) 7. Install roof support (Fig. 33) and roof flashing making sure upper flange is below the shingles. (Fig. 34) 8. Install appropriate pipe sections until the venting is above the flashing. (Fig. 34) 9. Install storm collar and seal around the pipe. 10. Add additional vent lengths for proper height. (Fig. 32) 11. Apply high temperature sealant to 4” and 7” collars of vertical vent termination and install.

Sheet Metal Screws (#5) (3 per joint) Sealant Storm Collar TWL101a If there is a room above ceiling level, a firestop spacer must be installed on both the bottom and the top sides of the ceiling joists. (Fig. 35) If an attic is above ceiling level, a 7DVAIS (Attic Insulation Shield) must be installed. NOTE: The enlarged ends of the vent sections are to always face downward. 11" (279 mm) 11" (279 mm) Attic Insulation Shield Joist Upper Floor Joist Firestop Spacer Nails (4) Ceiling In- stallation CFM100 Fig. 35 Firestop and attic insulation shield.
