Planning Your Dura-Vent
Installation
There are two basic types of Dura-Vent Direct
Vent System installations: horizontal termination
and vertical termination. Confi rm the maximum
horizontal run and maximum vertical rise from the
diagrams in the "Venting Arrangment" section.
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 construc-
tion.) 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
hazard. Do not fi ll air spaces with
insulation.
The minimum clearance requirements between
the outer wall of the vent pipe and nearby
combustible surfaces is 1-1/2", except when
passing through a wall, ceiling, or at the ter-
mination where the use of a fi restop or wall
thimble reduces the required clearance to 1".
Be sure to check the vent termination clearance
requirements from decks, windows, soffi ts,
gas regulators, air supply inlets and public
walkways as specifi ed in the "Exterior Vent
Terminal Locations" section and in your local
building codes.
To determine the length of vent pipe required
for vertical installations, measure the distance
from the unit fl ue outlet to the ceiling, the ceiling
thickness, the vertical rise in an attic or second
storey, and allow for suffi cient vertical height
above the roof line.
For multi-storey applications, fi re stops are
required at each fl oor level. If an offset is
needed, additional pipe, elbows and supports
will be required.
Do not exceed the maximum number of elbows.

o for horizontal terminations and two 45 o
