WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
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 BTUs (.3kWs) of gas input per hour. An unvented room heater is recommended as a
supplemental heater (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 insure that water vapor does not become a problem:
1. Be sure the heater is the proper size for the application, including adequate combustion air and circulation air.
2. If high humidity is experienced, the dehumidifier 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.

AIR FOR COMBUSTION AND VENTILATION

WARNING:
This heater shall not be installed in a confined space or unusually tight construction unless provisions
are provided for adequate combustion and ventilation air. Read the following instructions to insure proper fresh air
for this and other fuel-burning appliances in your home.
PRODUCING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code, NFPA 54/ANSI Z 223.1,Section 5.3, Air for Combustion and
Ventilation. All spaces in homes fall into one of the three following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 6 through 8 will help you classify your space and provide adequate ventilation.
Confined and Unconfined Space
The National Fuel Gas Code, ANS Z223.1 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 and an
unconfining space 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.
This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for
adequate combustion and ventilation air.
·
Adjoining rooms are connecting only if there are doorless passageways or ventilation grills between them
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in
buildings of unusually tight construction, you must provide additional fresh air.
