1. Follow installation Steps 1 and 2 under vertical instal-
lation section, page 16.
2. Remove shingles or other roof covering as necessary
to cut the rectangular hole for the support box. Cut the
hole 1/8 in. (3 mm) larger than the support box outline.
3. Lower the support box through the hole in the roof
until the bottom of the support box protrudes at least 2
in. (51 mm) below the ceiling (Figure 5.17). Align the
support box both vertically and horizontally with a level.
Temporarily tack the support box in place through the
inside walls and into the roof sheathing.

4. Using tin snips, cut the support box from the top corners
down to the roofline, and fold the resulting flaps over
the roof sheathing (Figure 5.18). Before nailing it to the
roof, run a bead of non-hardening mastic around the
top edges of the support box to make a seal between
it and the roof.
WARNING! Risk of Fire! Clean out ALL materials from
inside the support box and complete the vertical vent run
and termination.
5. Assemble the desired lengths of pipe and elbows
necessary to reach from the appliance up through
the round support box. Ensure that all pipe and elbow
connections are in their fully twist-locked position.
Assemble as instructed.
