IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
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 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.

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 5a and 5b
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.

Insulating For Cold Climates
When an appliance 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 appliance and on the inside of the exterior walls.
In a chase, it is a good idea to install a firestop at the
first ceiling level above the appliance. Also, install
insulation on the side walls. Insulation may then be
placed above the ceiling to assure the space around the
appliance is protected. Refer to Page 8, Figure 7.

Gas Line Installation
This appliance must be isolated from the gas supply
piping system by closing its individual manual shut off
valve during any pressure equal to or less than 1/2 psig
(3.45 kPa).
The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.45 kPa).
If gas piping from the source to the appliance location
has not been accomplished, install the required pipe.
Consult local plumbing code to assure proper pipe size.
The gas pipeline can be brought in through the right
side of the appliance. A knockout is provided 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 3/8"
copper tubing approved for propane or natural gas, 1/2"
rigid pipe or an approved flex connector, then reduced
to 3/8" to the appliance. Because some municipalities
have some additional local codes, it is always best to
consult your local authority.

U.S.: Consult the current National Fuel Gas Code,
ANSI Z223.1
Canada: CSA - B149.1 installation code.
Test for leaks. Use a 50/50 solution of liquid soap and
water to test for leaks at gas fittings and joints. Apply
water/soap solution with brush only -
do not over
apply. NEVER test with an open flame.
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 so that gas
line can be easily disconnected for burner or fan
servicing. See gas specification for pressure details
and ratings. NOTE: If flex connector is used, it must be
kept inside of the appliance. (Fig. 8)

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 car-
ried out by a licensed electrician.
Ensure that the power to the supply line
has been disconnected before commenc-
ing this procedure.
Once the fireplace is secured, complete wiring the fan
kit. Remove knockout in the center of the back of the
EB1 and install listed cable clamps. Feed electrical wire
through cable clamp leaving approximately six (6)
inches of wire exposed through the EB1. Secure cable
clamp to the wire.
Attach white wire from power source to one (1) wire of
receptacle and secure with a nut. Attach black wire from
power source to the other wire of the receptacle and
secure with a nut. Be sure nuts are tightened securely.
Secure the EB1 assembly to the inside of the electrical
box coverplate using two (2) screws. Attach the cover to
the face of the EB1 while being careful to position
excess wire completely within the EB1. Attach the
coverplate to the fireplace. (Fig. 11)

Operating Instructions
Glass Information
Only glass approved for use in Majestic
Fireplaces products may be used for
replacement.
•Glass doors are optional. The appliance may be
operated safely without glass doors.
•The use of any non-approved replacement glass will
void all product warranties.
•Bi-fold glass doors MUST BE completely open or
closed while the appliance is in operation.
•Care must be taken to avoid breakage of the glass.
•Under no circumstances should this appliance be
operated with broken glass. Replacement of the
glass as supplied by the manufacturer should be
completed by a licensed qualified service person.
•Replacement glass is available through your
Majestic Fireplaces dealer and should only be
installed by a licensed qualified service person.
Glass Cleaning
It will be 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. It is therefore recommended that the glass be
cleaned two or three times with a non-ammonia
household cleaner and warm water (we recommend
gas fireplace glass cleaner). After that the glass should
be cleaned two or three times during each heating
season depending on the circumstances present.
Clean glass after first two weeks of
operation.
Log Installation
1. Open glass door (if installed).
2. Remove logs from the packaging.
As with all plastic, these bags are not
toys and should always be kept away
from children and infants.
3. Place left rear log on rear log support. Ensure that
log is firmly positioned and there is no side-to-side
movement. (Figs. 15 & 16)
4. Carefully place Ember Left and Right Logs between
grate and burner. (Figs. 15 & 16)

Ember Material Placement
Separate the ember material into small pieces, roughly
1/2" in diameter and place on bracket over front burner
tube. Do not pack down; leave in loose, fluffy condition
for most realistic ember effect. (Fig. 15 & 16)
Lava Rock
The lava rock provided with this fireplace must be
placed on the firebox base on either side of the burner
assembly. Under no circumstances should lava rock
be placed on any part of the burner
assembly.
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 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 appli-
ance 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 each
lighting, vapor may condense and fog the glass; this
moisture disappears in a few minutes of burning.
Flame Adjustment
For units equipped with Hi/Lo valves, flame adjustment
is accomplished by rotating the Hi/Lo adjustment knob
located near the center of the gas control.

Flame Characteristics
It is important to periodically perform a visual check of
the pilot and the burner flames. Compare them to the
illustrations below (Figs. 18, 19, 20). If any of the
flames appear abnormal call a service person.
Red Glow Embers LG151

Inspecting the Venting System
The 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 (i.e.: carbon monoxide) into the
room.
To inspect the venting system, make sure the main gas
valve is off. Remove the glass panel. Using a flashlight,
check the combustion dome and behind the top grille.
Clean if necessary.

Maintenance
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:
• main burner
• gas orifice
• pilot burner
• thermopile
• combination millivolt gas valve
Most of these components may require only an occa-
sional checkup and cleaning and some may require
adjustment. If repair is necessary, it should be per-
formed by a qualified technician.
In order to properly clean the burner and pilot assembly,
turn off the gas to the unit, open the glass door (if
used), remove 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 3/8" or 1/2" of the thermopile should
be engulfed in the pilot flame. (Fig. 21)
To adjust pilot burner, turn pilot screw marked "pilot" for
proper flame size.
The air shutter is set at factory no adjustment should be
necessary.
Cleaning Electronic Ignition System
The Electronic Ignition burner/control system consists
of: • main burner
• gas orifice
• pilot burner
• 24VAC valve with transformer
Taking care of the Electronic Ignition units is almost
identical to taking care of the Standing Pilot models.
