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 replace location 
should be adjusted if obstructions are found in the wall.
3. Project a line from the center point of the ue outlet upward and outward to the desired ue 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 the exterior wall surfaces.
Please read and understand these instructions before installing. Failure to follow 
these instructions carefully could cause property damage or personal injury.
Figure 31: Wire Spacers.
4. Frame the hole as shown in Figure 35.
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) 1” wood 
screws. If a wall is greater than 8” (203mm) in depth, the clearance above 
the ex must be 4” (111mm)
6. Apply a bead of Mill-Pac Black sealant to the new Ø4” (10 cm) by 5” (12.5 
cm) provided ue collar adaptor. Press the ue collar into the ue outlet of 
the replace so that the Mill-Pac seals the ue collar to the ue outlet.

7. Stretch both the Ø4” (10 cm) ex vent and 
the  Ø6”  (16.25  cm)  ex  intake  liner  to 
the length needed to ensure the ex can be

over  the ex  vent. Install four (4)  wire 
spacers  around  the  ex  pipe.  Ensure  the

the pipes, and at each end of any elbows in 
the liners (refer to Figure 31 and 32).
