Design-certified to ANSI Z21.11.2b 1998. Gas-
Fired Room Heaters — Vol. II, Unvented Room
Heaters.
This gas room heater should be installed by a
qualified installer in accordance with local building
codes and with current National Fuel Gas Code.
ANSI Z223.1.
"This heater shall not be installed in a confined
space or unusually tight construction unless
provisions are provided for adequate combustion
and ventilation air".
"The
National Fuel Gas Code, ANSI Z233.1
defines a confined space as a space whose
volume is less than 50 cubic feet per 1,000 Btu
per hour (4.8m
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 cubic feet per 1,000 Btu per hour
(4.8 m
3
per kw) of the aggregate input rating of all
appliances installed in that space. Rooms
communicating directly with the space in which
the appliances are installed, through openings not
furnished with doors, are considered a part of the
unconfined space.
WARNING: If the area in which the heater may
be operated is smaller than that defined as an
unconfined space or if the building is of unusually
tight construction, provide adequate combustion
and ventilation air by one of the methods,
described in the National Fuel Gas Code,
ANSI Z 223.1, Section 5.3 or applicable local
codes."
Unusually tight construction is defined as
construction where:
a) Walls and ceilings exposed to the outside
atmosphere have a continuous water vapor
retarder with a rating of 1 perm (6 x 10-11 kg
per pa-sec-m2)
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 floors, between wall-
ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas
lines, and at other openings.
