• 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.
• Keep heater area clear and free from com-
bustible materials, gasoline and other flam-
mable vapors and liquids.
• Do not use this heater if any part has been
under water. Immediately call a qualified ser-
vice technician to inspect the room heater and
to replace any part of the control system and
any gas control which has been under water.
• Input ratings are shown in BTU per hour and
are for elevations up to 4,800 feet. Do not install
this heater at an elevation above 4,800 feet if the
gas supply has not been derated for that eleva-
tion. Consult your local gas supplier. (For op-
eration at elevations above 4,800 feet, equip-
ment ratings shall be reduced at the rate of 4
percent for each 1,000 feet above sea level
before selecting appropriately sized equipment.)
• Ensure that the heater is clean when operat-
ing. Excessive dust accumulation on the burner
and/or logs will increase the amount of carbon
monoxide formation and could lead to carbon
monoxide poisoning and/or 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).
Massachusetts And New York Require-
ments
These appliances are approved for installation
in the following USA locations listed in the
following:
Massachusetts:
These fireplaces are approved for installation
in the US state of Massachusetts if the follow-
ing additional requirements are met-
• Installation and repair must be done by a
plumber or gas fitter licensed in the Common-
wealth of Massachusetts.
• The flexible gas line connector used shall not
exceed 36 inches (92 centimeters) in length.
• The individual manual shut-off must be a T-
handle type valve.
• Vent-Free appliances may NOT be installed in
bedrooms or bathrooms.
• A working smoke detector must be installed
in the area where vent-free appliances are
installed.
Seller of unvented propane or natural gas-
fired supplemental room heaters shall pro-
vide to each purchaser a copy of 527 CMR 30
upon sale of the unit.
New York:
These fireplaces are approved for installation
in the US state of New York, but not in New
York city.
State or local codes may only allow operation of
this appliance (manual version only) in a vented
configuration. Check your state or local codes.
Superior Unvented Gas Log Room Heaters are
certified by OMNI to ANSI Z21.11.2 standard.
These gas log room heaters may be used as a
space heat source for a room in conjunction with
an approved unvented firebox. Additionally,
manually controlled units are design certified by
OMNI to ANSI 21.60 as a vented gas log set.
As such, manually controlled units may be used
as a vented gas log set in any wood-burning
fireplace that has been properly constructed to
code, and in the case of factory built fireplaces,
installed in compliance with manufacturers list-
ing and installation instruction.
Use of the manually controlled log sets covered
by this manual in a properly vented wood-
burning fireplace which has had the damper
blocked open as detailed in these installation
instructions preclude consideration of the com-
bustion and ventilation air and clearance to
combustible restrictions discussed herein.
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 (latest edition),
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
construction 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.
