Planning Your Dura-Vent
Installation
There are two basic types of Dura-Vent Direct
Vent System installations: horizontal termina-
tion and vertical termination. Confirm the max-
imum horizontal run and maximum vertical rise
from the diagrams on pages 13-16.
When planning your installation, it will be nec-
essary to select the proper length of vent pipe
for your particular requirements. For horizontal
installations, determine the minimum clearance
from the rear of the unit to the wall. It is also
important to note the wall thickness. (The wall
thimble is suitable for 2 x 4 or 2 x 6 wall
construction.) Select the amount of vertical
rise desired for "vertical-to-horizontal" type
installations.
Warning: Always maintain required
clearances (air spaces) to nearby
combustibles to prevent a fire haz-
ard. Do not fill air spaces with insu-
lation.
The minimum clearance requirements between
the outer wall of the vent pipe and nearby
combustible surfaces is 1-1/4 inch. Be sure to
check the vent termination clearance require-
ments from decks, windows, soffits, gas reg-
ulators, air supply inlets and public walkways
as specified in the Exterior Vent Terminal Lo-
cations on page 10 and in your local building
codes.
To determine the length of vent pipe required
for vertical installations, measure the distance
from the unit flue outlet to the ceiling, the ceiling
thickness, the vertical rise in an attic or second
storey, and allow for sufficient vertical height
above the roof line.
For multi-storey applications, fire stops are
required at each floor level. If an offset is
needed, additional pipe, elbows and supports
will be required.
Do not exceed the maximum number of elbows.
