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 pilot assembly is equipped with an Oxygen Depletion Safety (ODS) system which shuts off the
heater if not enough fresh air is available.
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
1011 kg per pa-sec-m
2
) or less with openings gasketed or sealed;
