Fresh Air Requirements for Combustion

the following instructions to insure proper fresh
air for this and other fuel-burning appliances in

Radiance® Vent-Free Gas Heater
Modern construction standards have resulted in homes
that are highly energy-efficient and that allow little heat
loss. Your home needs to breathe, however, and all
fuel-burning appliances within it require fresh air in
order to function properly and safely. Exhaust fans,
clothes dryers, fireplaces, and other fuel burning appli-
ances all use the air inside the building. If the available
fresh air is insufficient to meet the demands of these
appliances, problems can result.
The Radiance Unvented heater has specific fresh air
requirements. You must determine that these fresh
air requirements will be met within the space where
the appliance will be installed. The following informa-
tion will help you insure that adequate fresh air is avail-
able for the heater to function properly.
If the area in which the heater may be
operated does not meet the required volume
for indoor combustion air, combustion and
ventilation air shall be provided by one
of the methods described in the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, the
International Fuel Gas Code or applicable
local codes.
