The DVRTSB has been approved for mobile home
installations.
IMPORTANT:
PLEASE READ 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 a gas fireplace to give off some
odor 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 during burn in period.
It is recommended that you burn your fireplace for
at least ten (10) hours the first time you use it. If
the optional fan kit has been installed, place the fan
switch in the “OFF” position during this time.

Hearth
A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305mm) or more from
the front of the fireplace.
Cold climate installation recommendation:
When installing this unit against a noninsulated exterior wall or chase, it is
mandatory that the outer walls be insulated
to conform to applicable insulation codes.
Framing and Finishing
1. Choose the unit location.
2. Place the unit into position and secure it to the floor
with 1¹⁄₂” (38 mm) screws, or nails. The holes to
secure the unit to the floor are located just behind
the access door grille on the left and right side of the
unit.
3. Frame in the fireplace with a header across the top.
It is important to allow for the finished wall face when
setting the depth of the frame.
4. Drywall (sheetrock) or wood material may be placed
with a zero clearance to the top edges of the appli-
10003848
DVRTSB Bay Window Fireplace
ance when finishing walls above sides of the appli
ance with glass windows. Attach the wall finishing to
the constructed frame not the appliance.
5. On DVRTSB models, drywall, wood or wood molding
may be placed with zero clearance to the rear
wall of the unit, along the vertical edge formed
by the standoffs to intersection of the rear wall to the
side wall containing the small glass window. Attach
the wall finishing to the constructed frame, not the
appliance.
-
Final Finishing
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the appliance.
DO NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the edges
of the appliance.

Gas Line Installation
When purging the gas lines, the front glass
must be removed.
The gas pipeline can be brought in through the side and
back of the fireplace 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 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
flex connector. Since some municipalities have additional local codes, it is always best to consult your local
authority and the CSA-B149.1 installation codes.
For USA installations consult the current National Fuel
Gas Code, ANSI Z223.1/NFPA 54.
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.

installations must be in accordance with the
current ANSI Z223.1/NFPA 54 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).

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 flex connector use only approved
fittings. Always provide a union when using black iron
pipe so the gas line can be easily disconnected for
burner or fan servicing. Refer to the gas specification
for pressure details and ratings.
The fireplace valve must not be subjected
to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or any other gas
appliance control from the gas line when
pressure testing.
