The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.45 kPa).
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.
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 your Vermont Castings Majestic
Products Company 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 used in the
manufacturing process.
Please ensure that your room is well ventilated open all windows.
It is recommended that your burn your fireplace for at
least ten (10) continuous 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.
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.

Mantels
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting height and widths refer to
Figures 2a and 2b and the Mantel Chart below.
The distances and reference points are not affected by
the fitting of a bay window front trim kit.
Noncombustible mantels and legs may be installed at
any height and width around the appliance.
When using a paint or lacquer to finish the mantel, such
paint or lacquer must be heat resistant to prevent
discoloration.

Hearth
A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth.
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
Check fireplace to make sure it is levelled
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. The holes to
secure the unit to 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. 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” (13 mm), 5/8” (16 mm), or 3/4” (19 mm).
(Fig. 4)
5. Screw through the slotted holes in the drywall strip
and into pre-drilled 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 gas line the fornt glass
must be removed. Purging gas lines must
comply with ANSI Z223.1/NFPA 54 in USA
and CSA B149.1 in Canada.
The gas pipeline can be brought in through the right or
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, 1/2" rigid pipe or an approved
flex connector, then reduced to 3/8" (R Models) or 1/2"
(E Models) to the appliance. Because some municipalities have some additional local codes, it is always best
to consult your local authority and the CSA-B149.1
installation code.
For US 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 applied with a
brush no larger than 1" (25mm). Never
aply 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 psi.
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 up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union so that gas line can
be easily disconnected for burner or fan servicing.
Refer to gas specification for pressure details and
ratings. NOTE: If flex connector is used, it must be kept
inside of the appliance. (Fig. 5)

Alternate Switch Location
Remote switch can be installed on either side of the access door. Simply mount the switch to the switch bracket
provided. Screw the bracket on either side of the frame,
lining up the screws with the pre-punched holes. (Fig. 7)
Remote Switch Installation
1. Thread wire through the electrical knockout located
on either side of unit. 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. (Figs. 19 or 20, Page

EB-1 Electrical Box
The fireplace, when installed, must be
electrically connected and grounded in
accordance with local codes or, in the
absence of local codes, with the current
CSA C22.1 Canadian Electrical Code
For USA installations follow the local
codes and the national electrical code
ANSI/NFPA No. 70.
It is strongly suggested that the wiring of
the EB-1 Electrical Junction Box be
carried out by a licensed electrician.
Ensure that the power to the supply line
has been disconnected before commencing this procedure.
The EB-1 Electrical junction box has been supplied
standard on the DVRT 36/39/43 models to allow for the
easy installation of an optional fan kits
To connect the EB-1 box to the house electrical supply
follow the steps below.
1. Unscrew the retaining screw from the EB-1 base
plate (Fig. 8) 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. 8)
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.
8. Refit the socket assembly back into the electrical
box and replace the cover plate. Secure the cable
with the clamp on the outside of the unit to prevent
strain on the connections.
9. The EB-1 electrical junction box is now ready to
supply power to the FK12 or FK24 fan kits if fitted.
