IMPORTANT:
PLEASE REVIEW THE FOLLOWING
CAREFULLY
Remove any plastic from trim parts before turning
the fireplace ON.
It is normal for fireplaces fabricated of steel to give
off some expansion and/or contraction noises
during the start up or cool down cycle. Similar
noises are found with your furnace heat exchanger
or car engine.
It is not unusual for your gas fireplace to give off
some odour the first time it is burned. This is due
to the curing of the paint and any undetected oil
from the manufacturing process.
Please ensure that your room is well
ventilated - open all windows.
It is recommended that you burn your fireplace for
a least six (6) hours the first time you use it. If
optional fan kit has been installed, place fan in the
"OFF" position during this time.

REMOTE SWITCH INSTALLATION
FOR RN/RP
When purging gas line the front glass must
be removed.
The gas pipeline can be brought in through the right side,
left side 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 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.
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame 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.
1. Thread wire through the electrical knockout located on
either side 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.
3. Connect wiring to gas valve. (Fig. 8/9)

Non-Combustible Walls: Hole opening must be 7.5"
(190mm) in diameter. To locate hole centre consult with
appropriate fireplace specifications, page 4.
STEP 2
Measure wall thickness and cut adjustable zero clearance
sleeve parts to proper length (MAXIMUM 12"). Adjust
sleeve to maximum (10-3/8 x 9-3/8) and attach to firestop
with #8 sheet metal screws (supplied). (Fig. 15) Install
firestop assembly.
Fig. 15
STEP 3
Measure from fireplace collar face 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. 16.
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. 17.

STEP 5
,
,
,
VERTICAL SIDEWALL INSTALLATIONS
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 elbows or pipes and reattach to the
fireplace collar. (Fig. 16)
STEP 6
Recheck the fireplace to make sure that it is levelled,
properly positioned, and nailed or screwed to the floor.
If applied, the fireplace adjustable frame drywall strips
(nailing flanges) should be fastened. See Framing and
Finishing.
FINISHED
WALL
VENT
TERMINATION
(7DVRVT)
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. 21.
Minimum clearance between vent pipes and
combustible materials is one (2") 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.
Fig. 16
For some installations, it may be desirable 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 maximum horizontal vent run is 20 feet (6100mm)
when the vertical vent rise is 7.5 feet (2286mm). Fig. 17
