Dura-Vent Termination Kit
Planning Your Dura-Vent
Installation
There are two basic types of Dura-Vent Direct
Vent System installations: horizontal termination
and vertical termination. Confirm the maximum
horizontal run and maximum vertical rise from the
diagrams in the "Venting Arrangement" section.
When planning your installation, it will be necessary
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
hazard. Do not fill 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 termination where the use
of a firestop or wall thimble reduces the required
clearance to 1".

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"
section 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.
