STEP 3

Measure from fireplace collar to face of outside wall (add 2" for vent pipe overlap. Mark pipes and cut to length. It is very important that the two pipes are flush with the outside wall once the fireplace is in its final location. Fig. 13.

STEP 4

Slip 4" and 7" pipes onto respective flue collars. Make sure to fix to the fireplace collar the 4" pipe with three (3) screws before fixing the 7" pipe on the 7" collar. Both pipes must be on a level plane. Fig. 13.

STEP 5

Guide the vent termination 4" collar into the 4" pipe then the 7" collar into the 7" pipe. Do not force the venting into position. If the pipes do not line up with the termination collars, disassemble pipes and reattach to the fireplace collar. (Fig. 13)

STEP 6

Secure fireplace to floor through floor holes and adjustable frame drywall strip (nailing flange) to frame. (See Framing & Finishing Section)

VERTICAL SIDEWALL APPLICATIONS

Vent Starter Kit 7DVSK, plus Transition Elbow 7DVRT90 must be used in Vertical Sidewall installations. The 4" pipe must be centred inside the 7" pipe coming off the 7DVRT90 transition elbow.

Since it is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.

The graph showing the relationship between vertical and horizontal side wall venting will help to determine the various vent lengths allowable. Fig. 19.

Minimum clearance between vent pipes and combustible materials is one (1") inch (25

mm)on top, bottom and sides unless otherwise noted.

When vent termination exits through foundation less than 20" below siding outcrop, the vent pipe must flush up with the siding. A 7DVSS must also be used.

It is always best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length.

The horizontal vent run refers to the total length of vent pipe from the flue collar of the fireplace to the face of the outer wall.

Horizontal plane means no vertical rise exists on this portion of the vent assembly.

For some installations, it may be desireable to have some amount of the horizontal vent run immediately after the fireplace. A verti- cal rise must be used but can be located anywhere in the vent system, to meet the perimeters identified in the venting graph.

The maximum horizontal vent run is 20 feet (6100mm) when the vertical vent rise is 7.5 feet (2286mm). Fig. 14
