This gas room heater should be installed by a qualified installer,

ANSI Z223.1/NFPA 54.
In the Commonwealth of Massachusetts, all gas fittings
and installation of this heater shall only be done by a
licensed gas fitter or licensed plumber.
This heater shall not be installed in a confined space or un-
usually tight construction unless provisions are provided for
adequate combustion and ventilation air.
The National Fuel Gas Code, ANSI Z233.1/NFPA 54 defines a
confined space as a space whose volume is less than 50 cubic
feet per 1,000 Btu per hour (4.8m
3
per kw) of the aggregate in-
put rating of all appliances installed in that space and an uncon-
fined space as a space whose volume is not less than 50 cubic
feet per 1,000 Btu per hour (4.8 m
3
per kw) of the aggregate
input rating of all appliances installed in that space. Rooms
communicating directly with the space in which the appliances
are installed, through openings not furnished with doors, are
considered a part of the unconfined space.
WARNING:
If the area in which the heater may be operated is
smaller than that defined as an unconfined space or if the build-
ing is of unusually tight construction, provide adequate combus-
tion and ventilation air by one of the methods, described in the
National Fuel Gas Code, ANSI Z 223.1/NFPA 54, Section 5.3 or
applicable local codes.
Unusually tight construction is defined as construction where:
a) Walls and ceilings exposed to the outside atmosphere have
a continuous water vapor retarder with a rating of 1 perm (6
x 10-11 kg per pa-sec-m
2
).
b) Weather stripping has been added on openable windows
and doors, and
c) Caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates and
floors, between wall/ceiling joints, between wall panels, at
peneetrations for plumbing, electrical and gas lines and at
other openings.

IMPORTANT:
Please Review the Following Carefully
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 Vermont Castings,
Majestic Products fireplace for a least six (6) hours the first
time you use it. If optional fan kit has been installed, place fan
in the "OFF" position during this time.
WARNING: Do not install televisions or other elec-
tronic devices above this fireplace unless approved
by the electronics manufacturer.
