where not prohibited by local codes.
This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases, unless an available certified kit is used.
GAS LINE INSTALLATION
When purging gas line one of the glass
sides must be removed.
The gas pipeline can be brought in through the rear right
side (see Fireplace Specifications) of the appliance as well
as the bottom. Knockouts are provided at convenient
locations 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, 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 flex connector.
Since some municipalities have some
additional local codes, it is always best to
consult your local authority and the CAN/
CGA-B149 (1. or .2) Installation code or for
U.S.A Installations consult the current
National Fuel Gas Code, ANSI Z223.1
Always check for gas leaks with a mild
soap and water solution. Do not use anopen flamefor leak testing.
REMOTE SWITCH INSTALLATION
1. Thread wire through the electrical knockout located on
rear of fireplace. Do not cut wire or insulation on metal
edges. Ensure that wire is protected. Run the other
end to a conveniently located wall receptacle box.
2. Attach wire to switch and install switch into receptacle
box. Attach cover plate to switch.

STEP 3
Measure from fireplace collar to face of outside wall (add 2"
for vent pipe overlap. Mark pipes and cut to length. It is very
important that the two pipes are flush with the outside wall
once the fireplace is in its final location. Fig. 13.
STEP 4
Slip 4" and 7" pipes onto respective flue collars. Make sure
to fix to the fireplace collar the 4" pipe with three (3) screws
before fixing the 7" pipe on the 7" collar. Both pipes must
be on a level plane. Fig. 13.
STEP 5
Guide the vent termination 4" collar into the 4" pipe then the
7" collar into the 7" pipe. Do not force the venting into
position. If the pipes do not line up with the termination
collars, disassemble pipes and reattach to the fireplace
collar. (Fig. 13)
STEP 6

inside the 7" pipe coming off the 7DVRT90
transition elbow.
Since it is very important that the venting system
maintain its balance between the combustion air intake
and the flue gas exhaust, certain limitations as to vent
configurations apply and must be strictly adhered to.
The graph showing the relationship between vertical and
horizontal side wall venting will help to determine the
various vent lengths allowable. Fig. 19.
Minimum clearance between vent pipes and
combustible materials is one (1") inch (25
mm) on top, bottom and sides unless
otherwise noted.
When vent termination exits through
foundation less than 20" below siding outcrop,
the vent pipe must flush up with the siding. A
7DVSS must also be used.
It is always best to locate the fireplace in such a way that
minimizes the number of offsets and horizontal vent
length.
The horizontal vent run refers to the total
length of vent pipe from the flue collar of the
fireplace to the face of the outer wall.
Horizontal plane means no vertical rise
exists on this portion of the vent assembly.
For some installations, it may be desireable
to have some amount of the horizontal vent
run immediately after the fireplace. A vertical rise must be used but can be located
anywhere in the vent system, to meet the
perimeters identified in the venting graph.
The 4" pipe must be centred

VERTICAL SIDEWALL APPLICATIONS
The maximum number of 90 degree elbows per side wall
installation is four (4), (includes 7DVRT90 off back of unit)
The maximum number of 45 degree elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run.
The maximum number of elbow degrees in a system is
270º. (This does not include transition elbow from rear
vent to vertical vent).
Sample:1-90º
2-45º
3-45º

When one 90º elbow is installed directly onto another off
the back of the fireplace the maximum horizontal vent
length is 36" (914mm). Fig. 16.

Fig. 15
Fig. 16
Total-270º
Fig. 15
For each 45 degree elbow installed in the
horizontal run (while maintaining a constant
horizontal plane), the length of the horizontal
run MUST be reduced by 18" (457mm). This
does not apply if the 45 degree elbows are
installed on the vertical part of the vent
system.
If a 90 degree elbow is used in the horizontal
vent run (level height maintained) the maximum horizontal vent length is reduced by 36
inches. Fig. 18. This does not apply if the 90
degree elbows are used to increase or redirect a vertical rise.
Example: According to the vent chart the maximum
horizontal vent length is 20 ft.when the vertical height is 8
ft. from fireplace base height. If one 90 degree elbow is
required in the horizontal vent it must be reduced to 17 ft.
