WARNING
When used without adequate combustion and ventilation air,
heater may give off CARBON MONOXIDE, an odorless, poisonous
gas.
Do not install heater until all necessary provisions are
made for combustion and ventilation air. Consult the
written instructions provided with the heater for information
concerning combustion and ventilation air. In the absence of
instructions, refer to the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation, or applicable
local codes.
This heater is equipped with a PILOT LIGHT SAFETY SYSTEM
designed to turn off the heater if not enough fresh air is
available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner and
control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO DEATH.
Early signs of carbon monoxide poisoning resemble the u, with
headache, dizziness and/or nausea. If you have these signs,
heater may not be working properly. Get fresh air at once! Have
heater serviced.
Some people – pregnant women, persons with heart or lung
disease, anemia, those under the inuence of alcohol, those
at high altitudes – are more affected by carbon monoxide than
others.
The pilot light safety system senses the depletion of oxygen at
its location. If this heater is installed in a structure having a high
vertical dimension, the possibility exists that the oxygen supply
at the higher levels will be less than that at the heater. In this type
of application, a fan to circulate the structure air will minimize
this effect. The use of this fan will also improve the comfort level
in the structure. When a fan is used to circulate air, it should be
located so that the air ow is not directed at the burner.
• An unvented room heater having an input rating of more than
6,000 Btu per hour shall not be installed in a bathroom
• An unvented room heater having an input rating of more than
10,000 Btu per hour shall not be installed in a bedroom or
bathroom.
• Never burn solid fuels in a replace where a gas log set is
installed.

• Correct installation of burner, proper location of the heater
and annual cleaning are necessary to avoid potential
problems with sooting. Sooting, resulting from improper
installation or operation, can settle on surfaces outside the
replace.
• Avoid any drafts that could alter burner ame patterns. Do
not allow fans to blow directly into the replace. Do not place
a blower inside burn box area of rebox. Ceiling fans will
create drafts that alter burner ame patterns. Sooting and
improper burning will occur as a result of drafts.
• WARNING: Do not allow fans to blow directly into the replace.
Avoid any drafts that alter burner ame patterns.
• WARNING: Do not use a blower insert, heat exchanger insert
or other accessory not approved for use with this heater.

the solid-fuel burning replace, including frequency of such
examination and cleaning, by a qualied agency.
• The installation must conform with local codes or, in the
absence of local codes, with the National Fuel Gas Code,
ANSI Z223.1/NFPA54.
• NOTE: Installation and repair should be done by a qualied
service person. The appliance should be inspected before
use and at least annually by a qualied service person.
More frequent cleaning may be required due to excessive
lint from carpeting, bedding material, etc. It is imperative
that the control compartment, burners and circulating air
passageways of the appliance be kept clean.
• Any safety screen or guard removed for servicing an ap-
pliance must be replaced prior to operating the appliance.
Provide adequate combustion and ventilation air.
• The ow of combustion and ventilation air MUST NOT be
obstructed.
• 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 appliance.
• An unvented room heater intended for installation in a
solid-fuel burning replace shall comply with the following
instructions.
• A replace screen must be in place when the appliance is
operating and, unless other provisions for combustion air are
provided, the screen shall have an opening(s) for introduction
of combustion air.
• Solid-fuels shall not be burned in a masonry or UL 127
factory-built replace in which an unvented room heater is
installed.
• Any glass doors shall be fully opened when the appliance
is in operation.
• Any outside air ducts and/or ash dumps in the replace shall
be permanently closed at time of appliance installation.
• WARNING: Failure to keep the primary air opening(s) of
the burner(s) clean may result in sooting and property
damage.
• WARNING: Before installing in a solid-fuel burning replace,
the chimney ue and rebox must be cleaned of soot,
creosote, ashes and loose paint by a qualied chimney

IMPORTANT SAFETY INFORMATION

26532-5-0311Page 6
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must nd out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors in
the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the

in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
Propane (LP-Gas) is a ammable gas which can cause res
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precautions
which can protect both you and your family from an accident.
Read them carefully now, then review them point by point
with the members of your household. Someday when there
may not be a minute to lose, everyone's safety will depend
on knowing exactly what to do. If, after reading the following
information, you feel you still need more information, please
contact your gas supplier.

Unvented room heaters must be used as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application, including
ample combustion air and circulation air.

causing headaches or eye or lung irritation. This is a normal
and temporary occurrence.
The initial break-in operation should last 2-3 hours with the

by opening windows or doors to allow odors to dissipate. Any
odors remaining after this initial break-in period will be slight
and will disappear with continued use.
This appliance must not be used with glass doors in the

used to support combustion, the method by which the air is brought
to the space (vertical or horizontal duct) and by the total input rate
of all appliances in the space.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough
fresh air for combustion and ventilation. However, in buildings of
unusually tight construction, you must provide additional fresh air.
Unusually tight construction is dened as construction
where:
a. Walls and ceilings exposed to the outside atmosphere have
a continuous water vapor retarder with a rating of one perm
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

You must secure the gas appliance to the replace
oor. If not, the entire unit may move when you adjust
the controls. Movement of unit may cause shifting
of the optional decorative glass. Burner movement
could cause a gas leak.
Special care is required if you are installing the unit
into a sunken replace. You must raise the replace
oor to allow access to gas controls. This will insure
adequate air ow and guard against sooting. Raise
the replace oor using noncombustible materials.
Installation of Burner Support Legs
Four (4) Burner Support Legs are included with the Loft
Burner. Installation is optional if you have a VFRL (millivolt

Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity
of the unit. Where none exists, or where its size or location
is not adequate, contact your local authorized installer for
installation or relocation.

lines must be checked for leaks by the installer. This should
be done with a soap solution watching for bubbles on all
exposed connections, and if unexposed, a pressure test
should be made.
Never use an exposed ame to check for leaks. Appli-
ance must be disconnected from piping at inlet of control
valve and pipe capped or plugged for pressure test.
Never pressure test with appliance connected; control
valve will sustain damage!
A gas valve and ground joint union should be installed in the
gas line upstream of the gas control to aid in servicing. It is
required by the National Fuel Gas Code that a drip line be
installed near the gas inlet. This should consist of a vertical
length of pipe tee connected into the gas line that is capped
on the bottom in which condensation and foreign particles
may collect.
