Installation & Operating Instructions
This gas room heater should be installed by a qualified installer
in accordance with local building codes and with current National Fuel Gas Code. ANSI Z223.1/NFPA 54.
"This heater shall not be installed in a confined space or
unusually 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 (4.8m3 per kw) of the aggregate input rating of all appliances installed in that space
and an unconfined space as a space whose volume is not less
than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the
aggregate input rating of all appliances installed in that space
and an unconfined space as a space whose volume is not less
than 50 cubic feet per 1,000 Btu per hour (4.8m3 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:
smaller than that defined as an unconfined space of if the building is of unusually tight construction, provide adequate combustion 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-m2) or less with openings gasketed or
sealed, and
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
penetrations for plumbing, electrical, and gas lines, and at other
openings.
If the area in which the heater may be operated is
Fireplace screen (when equipped) must be closed while
the appliance is in operation.
WARNING: Do not allow LP tank below 1/4 full.

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 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.
Safety Devices
Adequate combustion and ventilation air must be provided. The flow of combustion and ventilation air MUST
NOT be obstructed.
Provide adequate clearances around the air opening
into the combustion chamber; and adequate accessibility clearance for servicing and proper operation. NEVER
obstruct the front opening of the heater or cover the top
and bottom louvres (grilles).
These heaters are equipped with a pilot system featuring an Oxygen Depletion Sensor (O.D.S.) shut-off
device. All unvented heaters are required to have this
system. The O.D.S. pilot will shut down the heater
when there is not enough fresh air available.
Report any parts damaged in shipment to your dealer.
Description
The UVC vent-free heaters are unique in featuring two
catalytic filters and a frame window with glass that actually
clean room air as well as give excellent zone heating.
The UVS vent-free heaters use a frame window with
screen mesh that does not use any catalytic filters.
Each model is available as Natural or Propane gas,
equipped with a standing pilot.
Design-certified to ANSI Z21.11.2a-2003. Gas-Fired
Room Heaters — Vol. II, Unvented Room Heaters.

Mantels
Depending on the width of the mantel it may be installed higher or lower from the combustion chamber
opening. This also applies to the distance between the
mantel leg (if installed) and the fireplace. Refer to Figures 3a and 3b for correct mounting heights and widths
for combustible mantels and mantel legs.
Noncombustible mantels and legs may be installed at
any height above the appliance opening.
When using paint or lacquer to finish the
mantel, such paint or lacquer must be heat
resistant to prevent discoloration.
Hearth Extension
A hearth extension in front of heater is recommended
but not required.
Planning
Planning the installation is an important first step: it will
save time and money later in the actual installation. In
planning the installation, consider:
1. Where the heater will be located.
2. All components needed to complete the
project.
Mounting the Heater
The heater should only be mounted on the following
surfaces:
• A flat combustible (burnable) surface.
• A raised wooden platform.
• A concrete block or other solid object placed be
neath each of the four corners of the heater.
To mount the heater:
1. Choose unit location.
2. Place unit in position and secure to floor with 1
screws, or nails. The holes to secure the unit to the
floor are located just behind the bottom louvre on the
left and right hand side of the unit.
3. Frame in heater with a header across the top. It is
important to allow for finished face when setting the
depth of the frame.
4. Attach heater to frame using adjustable frame drywall
strips (located behind access door for shipping). Preset
depth to suit facing material (adjustable to 1/2" , 5/8" or
3/4" depths). (Fig. 4)
5. Use existing screws in side of unit to attach drywall
strip. Measure from face of heater to face of drywall
strip to determine final depth. (Fig. 4)

Framing
Framing can take place before or after the heater is set
in place. The framing should be positioned to accommodate the wall covering and facing material. Framing
material should be 2x4 or heavier. Framing headers
may rest on top of heater. (Refer to Page 4, Figures 1
and 2 for heater and framing dimensions.)
Insulating for Cold Climates
When a heater is installed in a chase or an outside wall,
the enclosure should be insulated like any other wall
of the home. Insulation should be installed under the
heater and on the inside of the exterior walls. (Fig. 5)
NOTE: Insulating for cold climates is strictly a recommendation and not a requirement.
