This is an unvented gas-ﬁred heater. It uses air (oxygen) from the

room in which it is installed. Provisions for adequate combustion

and ventilation air must be provided.
Keep room area clear and free from combustible materials,

gasoline and other ﬂammable vapors and liquids.
Unvented gas heaters are a supplemental zone heater. They are not

intended to be a primary heating appliance. Water vapor produced

by an unvented heater can create moisture problems in a home

when operated for extended periods of time.
During manufacturing, fabricating and shipping, various

components of this appliance are treated with certain oils, ﬁlms or

bonding agents. These chemicals are not harmful but may produce

annoying smoke and smells as they are burned off during the initial

operation of the appliance; possibly causing headaches or eye or

lung irritation. This is a normal and temporary occurrence.
The initial break-in operation should last 2-3 hours with the burner

at the highest setting. Provide maximum ventilation by opening

windows or doors to allow odors to dissipate. Any odors remaining

after this initial break-in period will be slight and will disappear

with continued use.
This appliance must not be used with glass doors in the closed

position. This can lead to pilot outages and severe sooting outside

the ﬁreplace.
Do not use this room heater if any part has been under water.

Immediately call a qualiﬁed service technician to inspect the

room heater and replace any part of the control system and any

gas control which has been under water.

WARNING: This appliance is equipped for (natural or propane)

gas. Field conversion is not permitted.

GENERAL INFORMATION

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 BTU's (.3KW's) of gas input per hour.
Unvented room heaters must be used 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 insure 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 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

(an entire house).
