joists, roof rafters, framing or other materials will
obstruct the venting system. You may wish to re -
locate the appliance, or to offset, to avoid cutting
load-bearing members. There is a 1-7/8" offset
from the center of the support box to the center
of the DirectVent Pro 4" x 6 5/8" center. The Sup -
port Box can be installed with this offset oriented
in any direction.
Step 3.
To install Support Box in a flat ceiling
cut a square hole in the ceiling 13" x 13" cen -
tered on the hole drilled in Step 2. Frame the
hole as shown (Fig. 14).
Step 4.
Install the support box with the bottom
of the box 1" below the finished ceiling. Nailing
strips are provided that can be used to secure
the box to the framing and then sheet rocked
over or can be used a trim over sheet rock al -
ready in place.
Step 5.
Assemble the desired DirectVent Pro
Pipe Sections and Elbows necessary to reach
from the Support Box. Ensure that all Pipe and
Elbow connections are in their fully twist-locked
position.
Step 6.
Cut a hole in the roof centered on the
DirectVent Pro pipe from the Support Box. The
opening should be of sufficient size to allow a 1"
minimum clearance to combustibles. Continue to
assemble Pipe Sections and Elbows as neces -
sary to reach up through the roof line. Galvanized
Pipe and Elbows may be utilized in the attic, as
well as above the roof line. The galvanized fin -
ish is desirable above the roof line, due to higher
corrosion resistance.
Notes:
(1) If exact lengths or distances must be met be -
tween Elbow offsets or elsewhere, use the Pipe
Extensions to adjust onto standard Pipe Sections
(2) If an offset is necessary in the attic to avoid
obstructions, it is important to support the vent
pipe in order to avoid excessive stress on the El -
bows. Wall Straps or plumbers tape may be used
for this purpose (Fig. 16).
(3) Wherever possible, use 45° Elbows instead of
90° Elbows. The 45° Elbow offers less restriction
to the flow of flue gases and intake air.
