Venting Installation Instructions - Desa (V)T32N series Owner's Operation And Installation Manual

VENTING INSTALLATION INSTRUCTIONS

Note: If an offset is needed to avoid
obstructions, you must support the vent
pipe every 3 feet. Use wall straps for this
purpose (see Figure 19, page 14). When-
ever possible, use 45° elbows instead of
90° elbows. The 45° elbow offers less
restriction to the flow of the flue gases
and intake air.
5. Place the flashing over the pipe section(s)
extending through the roof. Secure the
base of the flashing to the roof and fram-
ing with roofing nails. Be sure roofing
material overlaps the top edge of the
flashing as shown in Figure 19, page 14.
There must be a 1" clearance from the
vent pipe to combustible materials.
6. Continue to add pipe sections until the
height of the vent cap meets the minimum
building code requirements described in
Figure 7 on page7

Note: You must increase vent height for
steep roof pitches. Nearby trees, adjoining
rooflines, steep pitched roofs and other
similar factors may cause poor draft or
down-drafting in high winds. Increasing
the vent height may solve this problem.
7. Twist-lock the vent cap onto the last sec-
tion of vent pipe.
Note: If the vent pipe passes through any oc-
cupied areas above the first floor, including
storage spaces and closets, you must enclose
pipe. You may frame and sheetrock the en-
closure with standard construction material.
Make sure and meet the minimum allowable
clearances to combustibles. Do not fill any of
the required air spaces with insulation.
