Approved Venting/Chimney Configurations
A. Side Wall Venting
In this venting configuration, the pipe rises directly from the back
of the Fireplace. The exhaust travels up, through two elbows, and out
through a side wall. See illustration on previous page.
Refer to Simpson Dura-Vent instruction regarding installation of
your Direct-Vent System.
Please note the following considerations for the location of the
vent terminal:
1. The horizontal run must rise a minimum of 1/4" per foot of
run toward the vent termination.
2. The termination must not be recessed into the the exterior
wall or siding.
3. Clearances must be maintained around the vent termination .
See illustrations on page 12.
4. Vinyl Siding requires protection from vented heat above the
termination. Use Simpson Dura-vent Vinyl Siding Heat
Shield Kit, part #950.
The venting should be located so that people cannot be burned by
accidentally touching hot vent surfaces while the Fireplace is in
operation.
The vent termination must be placed so that it cannot be damaged
by automobile doors, lawnmowers or yard equipment, or falling ice
and snow.
ALL VENT CLEARANCES MUST BE MAINTAINED.
CHECK YOUR VENT CLEARANCES AGAINST THE
ILLUSTRATIONS ON PAGE 12.
