Preparation
The use of wallpaper adjacent to this stove is not recommended, as the high heat given off by this stove may
adversely affect the binders in the adhesive used to apply
the wallpaper.
Before beginning, remove the window frame assembly
from the stove. Also check to make sure there is not hidden damage to the stove. Take a minute and plan out the
gas, vent and electrical supply. Refer to Window Frame
Assembly Removal Section.
Gas Line Installation
When purging gas line, the front window frame
assembly must be removed.
The gas pipeline can be brought in through the rear of
the stove as well as the bottom. Knockouts are provided
on the bottom behind the valve to allow for the gas pipe
installation and testing of any gas connection. It is most
convenient to bring the gas line in from the rear right side of
the valve as this allows fan installation or removal without
disconnecting the gas line.
The gas line connection can be made with properly tinned
3/8” copper tubing, 3/8” rigid pipe or an approved ex connector. Since some municipalities have additional local
codes, it is always best to consult your local authority and
the National Fuel Gas Code, ANSI Z3.1/NFPA 54 in the
USA or the CSA-B149.1 installation codes.
Always check for gas leaks with a mild soap and water
solution. Do not use an open ame for leak
testing.
The gas control is equipped with a captured screw
type pressure test point, therefore it is not necessary to
provide a 1/8” test point up stream of the control.
When using copper or ex connector use only approved
ttings. Always provide a union when using black iron pipe
so that the gas line can be easily disconnected for burner
or fan servicing . See gas specications for pressure details
and ratings.
The stove valve must not be subjected to any test pressures exceeding 1/ psi. Isolate or disconnect this or any
other gas appliance control from the gas line when pressure testing.

To join the twist lock pipes together, simply align the beads
of the male end with the grooves of the female end, then
while bringing the ends together, twist the pipe until the
ange on the female end contacts the external ange
on the male end. It is recommended that you secure the
joints with three (3) sheet metal screws, however this is
not mandatory with twist lock pipe.
To make it easier to assemble the joints we suggest putting
a lubricant (Vaseline or similar) on the male end of the twist
lock pipe prior to assembly.

When using Vermont Castings Group twist-lock pipe it is
not necessary to use sealant on the joints. The only areas
of the venting system that need to be sealed with high
temperature silicone sealant are the collars on the stove
and termination, and the sliding joint of any telescopic vent
section used in the system.

How to Use the Vent Graph
The vent chart should be read in conjunction with the
following vent installation instructions to determine the
relationship of the vertical and horizontal dimensions of
the vent system.
1. Determine the height of the center of the horizontal vent
pipe exiting through the outer wall. Using this dimension
on the Sidewall Vent Graph (Fig. 8), locate the point
intersecting with the slanted graph line.
. From the point of this intersection, draw a vertical line
to the bottom of the graph.
3. Select the indicated dimension, and position the stove
in accordance with same.
Example A:
If the vertical dimension from the oor of the unit is 11’
(3.4m) the horizontal run to the face of the outer wall must
not exceed 14’ (4.3 m).
Example B:
If the vertical dimension from the oor of the unit is 7’
(.14m), the horizontal run to the face of the outer wall
must not exceed 8¹⁄₂’ (.6 m).
Vertical dimension from the oor of the stove to
Vertical Sidewall Applications
Since it is very important that the venting
system maintain its balance between the combustion air intake and the ue gas exhaust,
certain limitations as to vent congurations
apply and must be strictly adhered to.
The vent graph showing the relationship between vertical
and horizontal side wall venting will help to determine the
various dimensions allowable.
Minimum clearance between vent pipes and combusti-
ble materials is one 1” (25mm) on top, bottom
and sides unless otherwise noted.
When the vent termination exits through founda-
tions less than 0” (508 mm) below siding outcrop,
the vent pipe must ush up with the siding.
It is always best to locate the stove in such a way that
minimizes the number of offsets and horizontal vent length
of vent pipe from the ue collar of the stove to the face of
the outer wall.
Horizontal plane means no vertical rise exists on this portion of the vent assembly.
• The maximum number of 90° elbows per side wall
installations is three (3).
• For RFSDV4 and RFSDV34 models, the maximum
horizontal rn for a minimum 1” (305 mm) vertical rise
is 3’ (914 mm). (Fig. 9)

• If a 90° elbow is used in the horizontal vent run (level
height maintained) the maximum horizontal vent length
is reduced by 36” (914 mm). (Fig. 10) This does not
apply if the 90° elbows are used to increase or redirect
a vertical rise. (Fig. 11)

Example: According to the chart the maximum
horizontal vent length is 0’ (6 m). However, if a 90°
elbow is used in the horizontal vent, maximum horizontal vent length is reduced to 17’ (5. m). In Figure
9, the total of Dim. A and Dim. B must not exceed 17’
(5. m).
• The maximum number of 45° elbows permitted per
installation is six (6). These elbows can be installed in
either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run, the
length of the horizontal run MUST be reduced by 18”
(457 mm). This does not apply if the 45° elbows are
installed on the vertical part of the vent system.
• The maximum number of elbow degrees in a system is
70°. (Fig. 1)
1 + + 3 + 4 = 70°

Vertical Sidewall Installations
STEP 1
Locate vent opening on the wall. It may be necessary to
rst position the stove and measure to obtain hole location. Depending on whether the wall is combustible or
noncombustible, cut opening to size. (Fig. 13)
For combustible walls rst frame in opening.
Combustible Walls: (Fig. 13) Cut a 9³⁄₈”H x 9³⁄₈”W (40
x 40 mm) hole through the exterior wall and frame as
shown.
Noncombustible Walls: (Fig. 13) Hole opening must be
7¹⁄₂” (190 mm) in diameter.
