OPERATING INSTRUCTIONS
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
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.
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
Majestic
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
Majestic
first time you use it. If optional fan kit has
been installed, place fan in the "OFF" position
during this time.

MAINTENANCE
Keep the control compartment, logs and burner
area surrounding the logs clean by vacuuming or
brushing at least twice a year. THE LOGS CAN
GET VERY HOT — HANDLE ONLY WHEN
COOL.
Always turn off gas to the pilot before cleaning.
For relighting, refer to lighting and operating
instruction.
PILOT CONTROL SYSTEM
The burner and control system consists of:
• main burner • pilot burner
• gas orifice• 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.
The air shutter is set at factory no adjustment
should be necessary.
It is important to periodically perform a visual check of the pilot and
the burner flames. See Figures 9
and 11.
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. See Figure 10.
