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 com-
bustible surfaces is 1-1/4 inch. Be sure to check
the vent termination clearance requirements from
decks, windows, soffi ts, gas regulators, air sup-
ply 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.
