ADEQUATE COMBUSTION AND VENTILATION AIR
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 Z223.1/NFPA 54), defines a
confined
space as a space whose volume is 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. An
unconfined
space
is defined 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.
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) or less with openings gasketed or sealed;
b) weather stripping has been added on operable 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, be-
tween wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.
This appliance is equipped for natural gas. Field conversion is not permitted.
