INSTALLATION INSTRUCTIONS:

1.Plan your installation and clearances to combustibles. Decide on a location for the unit that will meet the clearances noted in the venting section, and any or all local code requirements.

2. Set the appliance in the desired location. Determine if any wall studs, electrical wiring, or plumbing pipes are in the way of the venting system as it passes through the exterior wall. The fireplace location should be adjusted if obstructions are found in the wall.

3.Project a line from the center point of the flue outlet upward and outward to the desired flue outlet location on the exterior wall. Using this center point, scribe a 10” (25.4 cm) hole or square on the

wall. Cut the hole from the interior through

4. Frame the hole as shown in Figure 29.

 

5.Trim the wall thimble to match the wall thickness as necessary. Install the wall

thimble and secure it to the inner wall

frame using four (4) 1½” wood screws. If

a wall is greater than 8” (203mm) in depth,

the clearance above the flex must be 4⅜”

(111mm)
