Horizontal Installations - Rigid
Vent System
1) Set the unit in its desired location. Check to
determine if wall studs or roof rafters are in
the way when the venting system is attached.
If this is the case, you may want to adjust the
location of the unit.
2) Direct Vent pipe and fittings are designed with
special twist-lock connections to connect the
venting system to the appliance flue outlet. A
twist-lock appliance adaptor is installed on the
unit at the factory. Assemble the desired com-
bination of pipe and elbows to the appliance
adaptor with pipe seams oriented towards the
wall or ceiling, as much out of view as possible.
The final positioning of the pipe and 90
assembly is determined by the mounting orienta-
tion of the adaptor on the stove and twist-locked
for a solid connection.
Note:
a) Twist-lock procedure: Four indentations,
located on the female ends of pipes and fit-
tings, are designed to slide straight onto the
male ends of adjacent pipes and fittings, by
orienting the four pipe indentations so they
match and slide in to the four entry slots on
the male ends (Diagram 1). Push the pipe
sections completely together, then twist-
lock one section clockwise approximately
one-quarter turn, until the two sections
are fully locked. The female locking lugs
will not be visible from the outside on the
Black Pipe or fittings. They may be located
by examining the inside of the female ends.
b) Horizontal runs of vent must be supported
every three feet. Wall straps are available
for this purpose.
c) Snorkel Terminations:
For installations requiring a vertical rise
on the exterior of the building, 14-inch and
36-inch tall Snorkel Terminations and the
Riser Vent as shown in Diagrams 2 & 2a
are available. Follow the same installation
procedures as used for standard Horizontal
Termination. NEVER install the snorkel
upside down.

silicone to
female end.
NOTE: For best results and optimum perfor-
mance with each approved venting sys-
tem, it is highly recommended to apply
"Mill-Pac" sealant (supplied) to every
inner pipe connection. Failure to do so
may result in drafting or performance
issues not covered under warranty.
Silicone (red RTV) is optional.

Below Grade Snorkel Installation
If the Snorkel Termination must be installed
below grade, i.e. basement application, proper
drainage must be provided to prevent water
from entering the Snorkel Termination. Refer to
Vent Manufacturer Installation instructions for
details. Do not attempt to enclose the Snorkel
within the wall, or any other type of enclosure.
3) With the pipe attached to the stove, slide the
stove into its correct location, and mark the wall
for a 10" x 10" (inside dimensions) square hole.
The center of the square hole should line up
with the center line of the horizontal pipe, as
*As specified in CAN/
CSA B149.1 Installation
Code. Local codes or
regulations may require
different clearances.

grade terminations.
shown in diagram 3. Cut and frame the 10 inch
square hole in the exterior wall where the vent
will be terminated. If the wall being penetrated
is constructed of non-combustible material, i.e.
masonry block or concrete, a 7" diameter hole
is acceptable.
