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 materials, 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 com-
bustible materials, gasoline and other flammable
vapor and liquids. This fireplace should not be used
as a drying rack for clothing, nor should Christmas
stocking or decorations be hung in the area of it.

Installation & Operating Instructions
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
(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.
This appliance has been approved for aftermar-
ket mobile home installations.
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 you 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, 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 paint or lacquer to finish the mantel,
such paint or lacquer must be heat resistant to
prevent discoloration.

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 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 commenc-
ing this procedure.
The EB-1 electrical junction box has been supplied
standard on the NV360/580 models to allow for the
easy installation of an optional fan kit.
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. 7) 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. 7)
5. Connect black wire of the power supply line to the
brass screw (polarized) of the socket assembly.
Fig. 6 Alternate switch location.
FP1024
The fireplace valve must not be sub-
jected 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 ap-
proved fittings. Always provide a union when using
black iron pipe so the gas line can be easily discon-
nected for burner or fan servicing. (Fig. 4) See gas
specification for pressure details and ratings.

Glass Cleaning
It is necessary to clean the glass periodically. During
start-up, condensation, which is normal, forms on the
inside of the glass and causes lint, dust and other
airborne particles to cling to the glass surface. Also
initial paint curing may deposit a slight film on the glass.
After the first two weeks of operation, it is
recommended the glass be cleaned two or three times
with a non-ammonia household cleaner and warm
water (gas fireplace glass cleaner is recommended).
After initial use glass should be cleaned two or three
times during heating season.
Clean glass after first two weeks of
operation.
Do not clean glass when hot.
Do not use abrasive cleaners.
Do not strike or slam the glass.

First Firing
Upon completing the gas line connection, a small
amount of air will be trapped in the line. When first
lighting the unit with the pilot light, it will take a few
minutes to purge the trapped air. Once purging is
complete, the pilot and burner will light and operate as
indicated in the instruction manual. Subsequent
lightings of the appliance will not require purging.
When lit for the first time, the appliance will emit a slight
odor for an hour or two. This is due to paint and lubri-
cants used in the manufacturing process. After lighting,
vapor may condense and fog the glass; this moisture
disappears within a few minutes of burning.
Inspecting the Venting System
This appliance venting system was designed and
constructed to develop a positive flow adequate to
remove flue gases to the outside atmosphere.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gases.
To inspect the venting system, make sure the main gas
valve is off. Remove glass frame (See Window Frame
Assembly Removal Section). Using a flashlight, check
the area above the baffle in the combustion dome.
Clean if necessary.

Vent Safety Switch
This fireplace incorporates the use of a Vent Safety
Shut-off Switch. The sensor and wiring are factory
installed and should not be removed or altered during
installation.
In the event of total flue blockage the system will detect
the increased heat buildup and will automatically shut
down the main burner assembly.
The sensor is located above the firebox behind the top
louvre assembly. It is accessible by removing the top
louvre assembly.
CAUTION: The firebox, Vent Safety Switch sensor
and surrounding panels become very hot during
normal operation. Allow time for the components to
cool before carrying out any service or inspection.
If the sensor is activated and shuts off the burner
assembly, the following procedure should be followed:
•Observe that the pilot flame is still “ON”. If the pilot
flame has gone out the reason for the fireplace shut
down is not the vent safety switch.
•Turn the pilot flame “OFF” and close all controls.
Allow the fireplace to cool.
•Check the flue and venting components for blockage
or restrictions.
•Remove the front louvre assembly.
•Locate the sensor.
•Reset the sensor by pressing the reset pin between
the two wire terminals. (Fig. 18)
CAUTION: The components may still be hot.
•Light the fireplace and check for downdrafts.
•Operate the fireplace in the normal manner. If the
burner assembly shuts down again after a period of
operation, DO NOT ATTEMPT TO RESET THE
SENSOR AGAIN. Turn off the fireplace and contact
your service technician.
Electrical Connection
The sensor is wired in series between the wall mounted
“ON/OFF” switch and the Electronic Ignition Module
(Fig. 19) or the thermopile and the gas valve (Fig. 20)

Burner and Burner Compartment
It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and replace the logs as per the instructions in this
manual. Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
FK12 Fan Assembly
The fan unit requires periodic cleaning. At least once
per month in the operating season, open the lower
louvre panels and wipe or vacuum the area around the
fan to remove any build up of dust or lint.
Brass Trim
Clean the brass trim pieces using a soft cloth lightly
dampened with lemon oil. Do not use water or
household cleaners on any brass components.
Contact your local representative to arrange an annual
service program.
Cleaning the Standing
Pilot Control System
The burner and control system consists of
• burner tube •gas orifice
• pilot assembly •thermopile
