FOR SAFE INSTALLATION AND OPERATION
PLEASE NOTE THE FOLLOWING:
1. This fireplace gives off high temperatures and
should be located out of high traffic areas and away
from furniture and draperies.
2. Children and adults should be alerted to the hazards
of the high surface temperatures of this fireplace
and should stay away to avoid burns or ignition of
clothing.
3. Children should be carefully supervised when in the
same room as your fireplace.
4. Under no circumstances should this fireplace be
modified. Parts removed for servicing should be
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 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.
9. Under no circumstances should any solid fuels
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.
