WAT E R VA P O R : A B Y- P R O D U C T O F U N V E N T E D R O O M H E AT E R S
Water vapor is a by-product of gas combustion. An
unvented room heater produces approximately one
(1) ounce (30ml) of water for every 1,000 BTU's
(.3KW's) of gas input per hour.
Unvented room heaters are recommended as supple-
mental heat (a room) rather than a primary heat
source (an entire house). In most supplemental heat
applications, the water vapor does not create a
problem. In most applications, the water vapor en-
hances the low humidity atmosphere experienced
during cold weather.
