PLEASE READ THE INSTALLATION & OPERATING INSTRUCTIONS BEFORE USING APPLIANCE.
Thank you and congratulations on your purchase of a Majestic fireplace.
IMPORTANT: Read all instructions and warnings carefully before starting installation. Failure to follow these
instructions may result in a possible fire hazard and will void the warranty.
Installation & Operating Instructions
Important Curing/Burning Instructions .................................................................................3
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 un
usually tight construction unless provisions are provided for
adequate combustion and ventilation air.
This appliance is for supplemental heating only. It should not be
used as the primary heat source for a dwelling.
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 or 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 1011 kg per pa-sec-m
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.

California Health & Safety Code Sec. 25249.6
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 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.

The installation of your Majestic heater must
conform with local codes, or in the absence
of local codes, with National Fuel Gas Code,
ANSI Z223.1/NFPA 54 — latest edition. (EX
CEPTION: Do not derate this appliance for
altitude. Maintain the manifold pressure at
3.5 inches w.c. for Natural Gas and 10 inches
w.c. for LP gas.)
High Elevations
Input ratings are shown in BTU per hour and are
certified without deration from elevations up to
4,500 feet (1,370m) above sea level.
Nuisance outages may occur at altitudes above
4,500 feet (1,370m) if dirt, dust, lint and/or cobwebs are allowed to accumulate on burner and/or
ODS pilot. Monthly inspection and cleaning is
recommended for altitudes above 4,500 feet
(1,370m)
For elevations above 4,500 feet (1,370m), installations must be in accordance with the current
ANSI Z223.1/NFPA 54 and/or local codes having
jurisdiction.
Gas Line Connection
If gas piping from the source to the heater location has
not been accomplished, install the required pipe. Consult local codes to assure proper pipe size.
The gas pipeline can be brought in through the right or
left side of the heater, 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.
NOTE: The gas line connection can be made with proper 3/8" copper tubing, 1/2" rigid pipe or an approved flex
connector, then reduced to 3/8" to the heater. Because
some municipalities have some additional local codes, it
is always best to consult your local authority. Consult the
current National Fuel Gas Code, ANSI Z223.1/NFPA 54.
-
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. When using black iron pipe, always provide a union so the gas line can be easily disconnected for
burner or fan servicing. Use shut off valve before union
or flex connector. See gas specification for pressure
details and ratings. NOTE: If flex connector is used, it
must be kept inside of the heater. (Fig. 9)
Always check for gas leaks using a 50/50 solution of liquid soap and water. Apply water/soap
solution with brush only - do not over apply.
NEVER test with an open flame.

First Firing
Upon completing your gas line connection, a small
amount of air will be in the lines. When first lighting
unit with pilot light, it will take a few minutes to purge
themselves of this air. Once the purging is complete,
the pilot and burner will light and operate as indicated
in the instruction manual. Subsequent lightings of the
heater will not require such purging.
Odor During Operation
Neither natural gas nor propane gas give off an odor
when burned. The nature of a vent free combustion
system, however, is such that odors may occasionally
be produced during heater operation when impurities
exist in the immediate area. Cleaning solutions, paint,
solvents, cigarette smoke, candles, adhesives, new carpet or textiles, etc., all can create fumes. These fumes
may mix with combustion air and can create odor. Such
odors will disappear over time, however, the condition
can be alleviated by opening a window or otherwise
providing additional ventilation to the area.
Flame Adjustment
For fireplaces equipped with HI/LO valves, flame adjustment is accomplished by rotating the HI/LO adjustment knob located near the center of the gas control.

Burner and Burner Compartment
Maintenance
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/FK24 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.
Cleaning the Standing Pilot
Control System
The burner and control system consists of:
• main burner • pilot burner
• gas orifice • thermopile
• combination millivolt gas valve
Most of these components may require only an occasional checkup and cleaning and some may require adjustment. If repair is necessary, it should be performed
by a qualified technician.
In order to properly clean the burner and pilot assembly,
turn off the gas to the unit, remove the window frame
panel and logs exposing the burner and pilot assembly.
Clean all foreign materials from the top of the burner.
Check to make sure that burner parts are clean. Visually inspect pilot. Brush or blow away any dust or lint
accumulation If pilot orifice is plugged, disassembly
may be required to remove any foreign material from
the orifice or tubing.
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
or floating.
Typically, the top 1/8" of the thermopile should be engulfed in the pilot flame. (Fig. 21)
