VENTING INSTALLATION

HBDV7 Series Direct Vent Gas Fireplace

Vertical Sidewall Installation - Twist Lock Pipe

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 28 (For com- bustible walls first frame in opening.)

NOTE: When using flex vent, the opening will have to be measured according to the 1/2” (13 mm) rise in 12” (305 mm) vent run.

Combustible Walls: Cut a 9B\,”H x 9B\,”W (244 x 244 mm) hole through the exterior wall and frame as shown. Figure 28

Noncombustible Walls: Hole opening must be 7Z\x” (191 mm) in diameter.

Locate vent opening on wall.

Step 2

Secure firestop to the inside frame, center in the 9B\," x 9B\," 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 29

Step 4

Using appropriate length of pipe section(s) attach to fire- place with three (3) screws. Follow with the installation of the inner and outer elbow, again secure joints with three

(3) sheet metal screws.

Vertical Height Requirements

Step 5

Measure the horizontal length requirement including a 2” (51 mm) overlap, i.e. from the elbow to the outside wall face plus 2” (51 mm) (or the distance required if installing a second 90° elbow). Figure 30

Always install horizontal venting on a level plane.

Step 6

Use appropriate length of pipe sections - telescopic or fixed - and install. The sections which go through the wall are packaged with the starter kit, and can be cut to suit if necessary.

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