INSTALLATION
DURA-VENT
TERMINATION KIT
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 page 13.
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 instal-
lations.
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 of 1-1/4" (32mm) is
required between the outer wall of the vent
pipe and nearby combustible surfaces. Be
sure to check the vent termination clearance
requirements from decks, windows, soffits,
gas regulators, air supply inlets and public
walkways as specified in the Exterior Vent
Terminal Locations 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.
One 90
o for horizontal terminations and two 45 o
for vertical termination.
DURA-VENT VENTING COMPONENTS
The Simpson Dura-Vent Direct Vent System offers a complete line of component parts for
installation of both horizontal and vertical installation. Many items are offered in decorative black,
as well as galvanized finish. The galvanized pipe and fittings are used for concealed locations
such as attics or where corrosion is a factor, such as above the roof line. Decorative brass trim
kits are available for both wall thimbles and ceiling support boxes.
