• To check for leaks, always use a soapy water solution or
a sniffer. Never test by using an open flame.

• The area around the gas logset must be free of all
combustible materials, especially gasoline or other highly
flammable, vapor producing liquids.

• Due to high temperatures, locate this logset away from
both high traffic areas and furniture and draperies.

• Children and adults alike should be aware of the high
surface temperatures; to avoid the risk of burns or ignition
of clothing they should stay away.

• Do not touch any part of the logset other than the
controls while it is operating or immediately after you turn
it off.

• Supervise young children and pets carefully when they
are in the room where the logset is operating.

• Do not place clothing or other flammable material on or
near the logset.

• Make sure that any safety screen or guard, removed during
servicing, has been replaced before you use the logset.

• Do not, under any circumstances, install the logset in
any bedroom, bathroom, other small, enclosed room,
mobile home or recreational vehicle.

• Do not install the logset in a drafty area or use it with any
after-market blower system that may cause drafting and
consequently alter the flame pattern.

• It is imperative that you keep clear all burner areas, control
compartments and passageways for circulating air.

• Do not move the logset in any way that might dislodge
the logs from their fixed positions. If you bump the logset
check to see if you have dislodged anything.

• Provide adequate clearances around air openings into
the combustion chamber and adequate accessibility
clearance for servicing and proper operation. NEVER
obstruct the front opening of the fireplace.

• Avoid propane tank dropping below 25% full. This will
help keep soot from occurring.

General Information

In order to assure a safe and effective installa-
tion, only a qualified service person who is
familiar with the building codes and installation
techniques appropriate to your area may install
and service this appliance.

The Logsets have been designed and tested to operate
safely when installed according to the installation
instructions contained in this manual. Read all instructions
before starting the installation.

• The vent-free gas logset must be installed only in a
fireplace constructed of noncombustible material.

• These logsets are not for exterior use.

• This appliance is for supplemental heating only. It should
not be used as the primary heat source for a dwelling.

• The logset should be inspected before use and at least
annually thereafter. More frequent cleaning may be
necessary due to excessive lint from carpeting or bedding
material.

• In the United States, the installation and operation must
conform to local codes or, in the absence of local codes,
with the National Fuel Gas Code, ANSI Z223.1, latest
edition, CSA-B149.1 Installation Code, and with the
National Electrical Code, ANSI/NFPA70 (latest edition).
State or local codes may only allow operation of this
appliance in a vented configuratio. Check your state or
local codes. In Canada, check local province for proper
use or CSA-B149. Refer to pages 7 and 8 for installation
details.

• The gas logset 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 p.s.i.g. (3.5 kPa.) The gas logset must be
isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures
equal to or less than 1/2 p.s.i.g. (3.5 kPa.)

• Do not, under any circumstances, burn solid fuel (wood,
paper, coal) in the fireplace where you have installed your
logset. Do not use it for cooking. Put nothing on top of the
logs.

• The logset must be compatible with its fuel. Natural gas
requires different hardware than propane. Never attempt
to use natural gas with a propane logset or vice versa.

• For a propane burning logset, the supply tank must
include a high to low gas pressure regulator. The tank
must be outdoors. Do not, under any circumstances,
locate supply tanks inside any structure.

•  The fireplace must include a screen made of chain
mesh or a similar material. You must keep the screen
closed at all times during the operation of the logset; it will
protect you in the event of an explosion.

• WARNING: If the fireplace contains glass doors, they
must remain open at all times during the operation of the
logset, allowing combustion air to circulate.

• In order to avoid any possible gas leaks, apply pipe joint
compound to all non-flared, threaded connections involved
in this installation. For propane, the joint compound must
be resistant to the corrosive action of propane.

WARNING

This appliance is for installation in a solid-fuel
burning masonry fireplace with a working flue, a
U.L.-127 Listed manufactured solid-fuel burning
fireplace, in any Majestic ventless firebox or in
any listed ventless firebox enclosure certified to
I.A.S. U.S. requirements 2-97.

NOTICE

This is an unvented gas-fired heater. It uses air
(oxygen) from the room in which it is installed.
Provisions for adequate combustion and
ventilation air must be provided. Refer to pages 5
and 6.

This appliance operates as an unvented domestic
room heater when fitted to a masonry or factory-built
wood-burning fireplace with the flue damper closed,
or as a decorative appliance when the flue damper is
fully open. It must not be used for any other purpose
and must be fitted in a masonry or factory-built
fireplace or ventless firebox enclosure.
