replaced prior to operating this fireplace again.
5. Installation and any repairs to this fireplace must be
performed by a qualified installer, service agency or
gas supplier. A professional service person should be
contacted to inspect this fireplace annually. Make it a
practice to have all of your gas fireplaces checked
annually. More frequent cleaning may be required due
to excess lint and dust from carpeting, bedding
material, etc.
6. Control compartments, burners and air passages in
this fireplace should be kept clean and free of dust
and lint. Make sure the gas valve and pilot light are
turned off before you attempt to clean this fireplace.
7. The venting system (chimney) of this fireplace should
be checked at least once a year and if needed your
venting system should be cleaned.
8. Keep the area around your fireplace clear of
combustible materials, gasoline and other flammable
vapor and liquids. This fireplace should not be used
as a drying rack for clothing, nor should Christmas
stockings or decorations be hung in the area of it.
9. Under no circumstances should any solid fuels (wood,
coal, paper or cardboard etc.) be used in this fireplace.
10. The flow of combustion and ventilation air must not be
obstructed in any way.
11. When fireplace is installed directly on carpeting, vinyl
tile or any combustible material other than wood, this
fireplace must be installed on a metal or wood panel
extending the full width and depth of the fireplace.
12. This fireplace requires adequate ventilation and
combustion air to operate properly.
13. This fireplace must not be connected to a chimney
flue serving a separate solid fuel burning fireplace.
14. When the fireplace is not in use it is recommended
that the gas valve be left in the “OFF” position.
10002428
Proposition 65 Warning: Fuels used in gas, woodburning or oil fired appliances, and the products of
combustion of such fuels, contain chemicals known to
the State of California to cause cancer, birth defects and
other reproductive harm.
California Health & Safety Code Sec. 25249.6
This appliance may be installed in an aftermarket
permanently located, manufactured home or mobile home,
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 a certified kit is used.
The DVRT36RMH has been approved for mobile home
installations.
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 Vermont Castings, Majestic
Products 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.
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.

Framing & Finishing
Check the fireplace to make sure it is
leveled and properly positioned.
1. Choose the unit location.
2. Place the unit into position and secure it to the floor
with 1¹⁄₂” (38mm) screws or nails. Holes for securing
the unit to floor are located behind the access door
grille on the left and right sides 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. Attach the fireplace to the frame using the
adjustable frame drywall strips (located behind the
access door for shipping). Preset the depth to suit
the facing material of the wall. The strips are
adjustable to 1/2” (13mm), 5/8” (16mm) or
3/4” (19mm). (Fig. 5)
5. Screw through the slotted holes in the drywall strip
and into predrilled holes in fireplace side. Measure
from face of fireplace to the face of the drywall strip to
confirm the final depth.

Gas Line Installation
When purging the gas lines, the front
glass must be removed.
The gas pipeline can be brought in through the side 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
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 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.

Remote ON/OFF Switch Installation
Do not wire the remote ON/OFF wall
switch for this gas appliance into a 120 V
power supply.
1. Thread the wiring through the electrical knockout
located on either side of the unit. Take care not to
cut the wire or insulation on metal edges. Ensure
the wire is secured and protected from possible
damage. Run one end to the gas control valve and
the other end to the conveniently located wall
switch.
2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box. Attach the cover
plate to the switch.
3. Connect the wire to the gas control valve. (Fig. 7)

Fig. 6 Typical gas supply installation.
Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25 mm). Never
apply soap and water solution with a
spray bottle. Do not use an open flame
for leak testing.
The fireplace valve must not be
subjected to any test pressures
exceeding 1/2 p.s.i. Isolate or disconnect
this or any other gas appliance control
from the gas line when pressure 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 upstream of the control.
When using copper or flex connector use only approved fittings. Always provide a union when using
black iron pipe so that the gas line can be easily
disconnected for burner or fan servicing. (Fig. 6) See
the gas specifications for pressure details and ratings.

follow the steps below:
1. Unscrew the retaining screw from the EB-1 base
plate (Fig. 9), and remove the EB-1 assembly from
the fireplace.
2. Remove the front cover of the EB-1 box.
3 Remove the plug socket assembly from the EB-1
box.
4. Feed the supply line in from the outside through the
cable clamp. (Fig. 9)
5. Connect black wire of the power supply line to the
brass screw (polarized) of the socket assembly.
6. Connect the white wire of the power line to the
chrome screw of the socket assembly.
7. Connect the ground wire of the supply line to the
green screw of the socket assembly.

General Information for Connecting Vent Pipes
Crimped End Pipes
Before joining elbows and pipes, apply a bead of high
temperature sealant to the crimped end of the elbow or
pipe.
Join the pipes using a 2” (51mm) overlap and secure
the joints with three (3) sheet metal screws. (Fig. 16)
Wipe off excess sealant.
Canadian Installations:
The venting system must be installed in accordance
with the current CSA-B149.1 installation code.
USA Installations:
The venting system must conform to local codes and/
or the current National Fuel Code ANSI Z223.1/NFPA
54.

Vermont Castings, Majestic Products DVRT36/39/ 43
Twist-lock Pipes
When using Vermont Castings, Majestic Products
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 fireplace and the sliding joint of any
telescopic vent section used in the system.
To join twist-lock pipes together, simply align the beads
of the male end with the grooves of the female end,
twisting the pipe until the flange on the female end
contacts external flange 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. (Fig. 17)
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.

How to Use the Vent Graph
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between 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 below, locate
the point intersecting with the slanted graph line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
3. Select the indicated dimension, and position the
fireplace in accordance with same.
Example A:
If the vertical dimension from the floor of the fireplace is 11’ (3.4m), the horizontal run to the face of
the outer wall must not exceed 14’ (4.3m).
Example B:
If the vertical dimension from the floor of the unit is
7’ (2.14m), the horizontal run to the face of the outer
wall must not exceed 8¹⁄₂’ (2.6m).

Rear Wall Vent Installation
Step 1
Locate and cut the vent opening in the wall.
For combustible walls, first frame in opening. (Fig. 20)
Combustible Walls: Cut a 10³⁄₈”H x 9³⁄₈”W
(265 x 240mm) hole through the exterior wall and
frame as shown.
Noncombustible Walls: Hole opening should be
7¹⁄₂” (190mm) in diameter.
Zero clearance sleeve is required only
for combustible walls.
Step 2
Measure wall thickness and cut zero clearance sleeve
parts to proper length (maximum 12” / 305mm). Assemble sleeve to its maximum opening (10³⁄₈” x
9³⁄₈”)(265 x 240mm), and attach to firestop with #8
sheet metal screws (supplied). Install firestop assembly. (Fig. 21)
Step 3
Measure the horizontal length requirement for the
venting including a 2” (51mm) overlap; i.e., from the
elbow to the outside wall face plus 2” (51mm).
(Fig. 19)
Step 4
Install the 4” (102mm) vent to the appliance collar and
secure with 3 sheet metal screws. Install the 7”
(175mm) vent pipe to the appliance collar and secure
with 3 sheet metal screws. If a 45° elbow is being

It is critical that there is no downward
slope away from the appliance when
connecting the vent or elbow.
Step 5
Guide the venting through the vent hole as you place
the appliance in its installed position. Guide the 4”
(102mm) and 7” (175mm) collars of the vent
termination into the outer ends of the venting. Do not
force the termination. If the vent pipes do not align with
the termination, remove and realign the venting at the
appliance flue collars. (Fig. 22) Attach the termination
to the wall as outlined in the instruction sheet supplied
with the termination.
