Horizontal Termination
The termination must fall within the area shown in
Figures 11 & 12.
A minimum of 24" vertical rise is required directly
off the heater unless a minimum 1
4” snorkel is
used.
In this case, a 12” vertical rise is required
directly off the heater.
Minimum horizontal run at the above conditions is
9”, the maximum horizontal run is 5’ providing a
1/4” rise is provided for every 12” of horizontal
run.
With 3’ of vertical rise from the stove top,
maximum horizontal run is 10’ providing a 1/4”
rise is provided for every 12” of horizontal run.
Use a vinyl siding Stand-Off when installing
against vinyl siding. The termination cap must not
be recessed into the wall or siding. Do not fill air
spaces with any type of insulation material.
A minimum 10” x10” square hole is necessary for
proper pipe clearance through a wall, provided
the vent is positioned to maintain 2” minimum
clearance at the to
p. A 1” minimum clearanc e
must be maintained to combustible materials
around the other sides.
All horizontal terminations must also comply with
the
clearance
specifications
to
adjacent
structures outlined in Figures 8 &11.
NOTE: For each 90
0
elbow after 2, remove 5' from
the allowable horizontal run. For Canadian
installations:
remove 4' from the allowable
horizontal run.

Minimum Vent Installation Instructions
1. Install the 24
” pipe section onto the starter collar
by fully inserting it and turning approximately ¼
turn clockwise, until the 2 sections are fully
locked. Install the 90º elbow in similar fashion.
2. Move the stove and pipe assembly back until the
90º elbow is flush to the wall. The 24
” vertical pipe
should be parallel to the wall. Draw a circle
around the pipe. Use the center of this circle as
the center point of the 10” x 10” square wall pass
through. Cut and frame the wall pass through.
3.
Place the interior wall thimble into the 10” x 10”
wall pass through. Secure it with 4 screws (not
provided). Install the exterior portion of the
thimble in similar fashion, overlapping the 2
sections.
CAUTION: FOR BUILDINGS WITH VINYL SIDING,
INSTALL A VINYL SIDING STANDOFF BETW EEN
THE VENT CAP AND THE EXTERIOR WALL.
4. Install the horizontal vent termination on the
outside of the wall. Ensure both of the retaining
straps extend through interior wall thimble. Before
attaching the vent termination to the outside of
the house, run a bead of non-hardening mastic
around its’ outside edges, so as to make a seal
between it and the wall. The arrow on the end cap
should point up. Secure the cap to the wall with
the appropriate screws.
Place the thimble cover onto the 90º elbow. Put
the 9” pipe into the horizontal vent cap, (the vent
pipe must extend into the horizontal vent cap a
minimum of 1-
1/4”). Move the stove and vent pipe
into position, insert the 9” pipe into the 90º elbow
and twist to lock it. Secure the straps from the
horizontal vent termination to the interior pipe with
2 sheet metal screws, keeping the screws as
close to wall thimble as possible. Bend or cut the
excess strapping so that the thimble cover will fit
properly. Screw the thimble cover to the wall.

Installation Components
Centerlines shown are approximate. Ensure you dry
fit your venting and take a measurement. Pipe
dimensions will vary by manufacturer and supplier.
These dimensions are using typical Simpson Dura -
Vent GS components. See installation instructions on
