WATER VAPOR: A BY-PRODUCT OF
UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combus-
tion. An unvented room heater produces ap-
proximately one (1) ounce (30 mL) of water
for every 1,000 BTUs (0.3 KWs) of gas input
per hour. Unvented room heaters are recom-
mended as supplemental 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 enhances
the low humidity atmosphere experienced
during cold weather.
The following steps will help ensure that water
vapor does not become a problem.
1. Be sure the heater is sized properly for the
application, including ample combustion
air and circulation air.
2. If high humidity is experienced, a dehu-
midifier may be used to help lower the
water vapor content of the air.
3. Do not use an unvented room heater as
the primary heat source.
UNPACKING
1. Remove top inner pack.
2. Tilt carton so that heater is upright.
3. Remove protective side packaging.

5. Remove protective plastic wrap.
6. Hold the screen, lift, and pull forward.
