Vertical Sidewall Installation -

Step 1

Locate vent opening on the wall. It may be necessary to first position the fireplace and measure to obtain hole lo- cation. Depending on whether the wall is combustible or noncombustible, cut opening to size. Figure 11 (For com- bustible walls first frame in opening.)

Combustible Walls: Cut a 10Z\x”H x 10Z\x”W (267 x 267

mm)hole through the exterior wall and frame as shown. Figure 11

Noncombustible Walls: Hole opening must be 8Z\x” (216 mm) in diameter.

Step 2

Secure firestop to the inside frame, center in the 10Z\x" x 10Z\x" vent opening.

Step 3

Place fireplace into position. Measure the vertical height

(X)required from the base of the flue collars to the center of the wall opening. Figure 12

Step 4

Using appropriate length of pipe section(s) attach to fire- place with three (3) screws. Follow with the installation of the elbow.

Step 5

Measure the horizontal length requirement figuring a 1Z\v” (32 mm) overlap, i.e. from the elbow to the outside wall cap. Figure 13

Always install horizontal venting on a level plane.

Step 6

Use appropriate length of pipe sections - telescopic or fixed - and install.

Sealing vent pipe and firestop gaps with high tem- perature sealant will restrict cold air being drawn in around fireplace.

Step 7

Guide the vent terminations 5” and 8” collard into their respective vent pipes. Double check that the vent pipes overlap the collars by a minimum of 1Z\v" (32 mm). Secure the termination to the wall with screws provided and caulk around the wall plate to weatherproof. As an alternative to screwing the termination directly to the wall, you may also use expanding plugs or an approved exterior construction adhesive.

Support horizontal pipes every 36” (914 mm) with metal pipe straps.
