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 "Rigid Pipe Venting Sys-
tems" 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 fill 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, 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.

You will require the following components with
your new Direct Vent Freestanding Gas Stove.
Please review your product to make sure you
have everything you need. In the event that
you are missing any part, contact your dealer.
Note: These are the minimum pieces re
-
quired. Other parts may be required
for your particular installation. See
above for a list of vent parts.
