Step 5: Cut the Hole for the Flue pipe
Using a hole saw attachment and an electric drill, cut a 2
1
/2

figure 7).
After the hole is cut, use a straight edge and a level to
be sure the inside opening is approximately
1
A inch
higher than the outside opening.
NOTE: After cutting the inside wall, remove the
insulation. Make sure there are no obstructions
inside the wall, such as electrical wiring, water
pipes, hot air ducts, etc.
Step 6: Install the Flue Pipe
From INSIDE the building, insert the flue pipe (with
arrow pointing "up") into the hole. Fasten the flue pipe

Step 7: Install the Outer Flange
Apply caulking material to the inside ridge of the rubber
packing (Figure 9).
Holding the "Up" mark to the top, slide the rubber
packing onto the sleeve (caulk side to the wall).
NOTE: If it is difficult to slide the packing onto the
sleeve, apply soapy water to the inside of the
packing.
Once the rubber packing is in place, slide the outer
flange onto the sleeve with the conical side pointing
outward (Figure 10).
Screw the flue pipe nut onto the flue pipe grooves, and
tighten it firmly (Figure 10).
