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. 16)
STEP 6
Secure fireplace to floor through floor holes and adjust- able frame drywall strip (nailing flange) to frame. (Refer to Framing & Finishing Section).

Vertical Sidewall Applications
Since it is very important that the vent- ing 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 Vent Graph shows the relationship between vertical and horizontal side wall venting and will help to determine the various dimensions allowable.
Minimum clearance between vent pipes and combustible materials is one 1"(25mm) on top, bottom and sides unless otherwise noted.
When vent termination exits through foundations less than 20" below siding outcrop, the vent pipe must flush up with the siding. 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.
•The maximum horizontal vent run is 20 ft. (6100 mm) when the vertical vent rise is 7¹⁄₂ ft. (2286 mm). (Fig. 17)
•The maximum number of 90° elbows per side wall installation is three (3).

•If a 90° elbow is used in the horizontal vent run (level height maintained) the maximum horizontal vent length is reduced by 36" (914 mm). (Fig. 18) This does not apply if the 90° elbows are used to increase or redirect a vertical rise. (Fig. 19)
