WARNING: FAILURE TO COMPLY WITH
THE INSTALLATION AND OPERATING IN-
STRUCTIONS PROVIDED IN THIS DOCU-
MENT WILL RESULT IN AN IMPROPERLY
INSTALLED AND OPERATING UNVENTED
ROOM HEATER, VOIDING ITS WAR-
RANTY. ANY CHANGE TO THIS HEATER
AND/OR ITS OPERATING CONTROLS IS
DANGEROUS. IMPROPER INSTALLA-
TION OR USE OF THIS HEATER CAN
CAUSE SERIOUS INJURY OR DEATH
FORM FIRE, BURNS, EXPLOSION OR
CARBON MONOXIDE POISONING.
WARNING: THESE APPLIANCES ARE
DESIGNED TO OPERATE ON NATURAL
OR PROPANE GAS ONLY. THE USE OF
OTHER FUELS OR COMBINATION OF
FUELS WILL DEGRADE THE PERFOR-
MANCE OF THIS SYSTEM AND MAY BE
DANGEROUS.
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to the
flu with headaches, dizziness and/or nausea. If
you have these signs, obtain fresh air immedi-
ately. Turn off the gas supply to the heater and
have it serviced by a qualified professional, as
it may not be operating correctly.
• Due to high temperatures, the heater should
be located out of traffic and away from furniture
and draperies.
• Children and adults should be alerted to the
hazard of high surface temperatures and should
stay away to avoid burns or clothing ignition.
• Young children should be carefully super-
vised when they are in the same room with the
heater.
• Do not place clothing or other flammable
material on or near the heater for the purpose of
drying.
• Installation and repair should be done by a
qualified service person. The heater should be
inspected before use and at least annually by a
professional service person. More frequent
cleaning may be required due to excessive lint
from carpeting, bedding material, etc. It is im-
portant that control compartments, burners
and circulating air passageways of the heater be
kept clean.
• Allow the heater to cool before servicing.
Always shut off any electricity or gas to the
heater while performing service work.
• Do not install these heaters in a bedroom or
bathroom.
• The installation must conform with local
codes or, in the absence of local codes with the
National Fuel Gas Code, ANSI Z223.1.
• The heater and its individual shut-off valve
must be disconnected from the gas supply
piping system while performing any tests of the
gas supply piping system at pressures in ex-
cess of ¹⁄₂ psig.
• The heater must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure test-
ing of the gas supply piping system at test
pressures equal to or less than ¹⁄₂ psig.
• Any safety screen or guard removed for
servicing the heater must be replaced prior to
operating the heater.
• Keep heater area clear and free from com-
bustible materials, gasoline and other flam-
mable vapors and liquids.
• Do not use these appliances if any part has
been under water. Immediately call a qualified
professional service technician to inspect the
appliance and to replace any parts of the control
system and any gas control which have been
under water.
• Test gage connections are provided on the
front of the gas control valve (identified A for
the manifold side and E for inlet pressure).
• Operation of these catalytic systems at alti-
tude will result in sporadic nuisance outages of
the pilot system due to lack of sufficient oxy-
gen, increasing in frequency as the altitude
increases above 4,500 feet. Although this
situation is not dangerous, pilot outages can-
not be tolerated.
• These catalytic appliances are rated for
use at altitudes no greater than 5,500 feet. Do
not install and use this appliance in locations
in excess of this altitude.
• Ensure that the heater is clean when operat-
ing. Excessive dust accumulation on the burner
and logs will increase the amount of carbon
monoxide formation and could lead to carbon
monoxide poisoning and death.
CODES
Adhere to all local codes or in their absence the
latest edition of The National Fuel Gas Code
ANSI Z223.1 or NFPA54 which can be obtained
from The American National Standards Insti-
tute, Inc. (1430 Broadway, New York, NY,
10018) or National Fire Protection Association,
Inc. (Batterymarch Park, Quincy, MA, 02269).
COMBUSTION AND VENTILATION AIR
These heaters shall not be installed in a con-
fined space. The heater may be located in
unusually tight construction provided the
space is unconfined, or if confined, is pro-
vided with two permanent openings commu-
nicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 1992, Section
5.3). Generally 50 ft
3
per 1,000 BTU input of
all operating appliances in the space.
The National Fuel Gas Code defines a con-
fined space as a space whose volume is less
than 50 ft
3
per 1,000 BTU/Hr (4.8 m
3
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 ft
3
per 1,000 BTU/Hr (4.8 m
3
per kw)
of the aggregate input rating of all appliances
installed in that space. Rooms communicat-
ing directly with the space in which the appli-
ances are installed, through openings not
furnished with doors, are considered a part of
the unconfined space.
Unusually tight construction is defined as con-
struction where:
a. wall and ceilings exposed to the outside
atmosphere have a continuous water vapor
retarder with a rating or one perm or less with
openings gasketed or sealed, and
b. weather stripping has been added on oper-
able 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 penetra-
tions for plumbing, electrical, and gas lines,
and at other openings.
Use the following equations to determine if you
have a confined or unconfined space.
