Watervaporisaby-productofgascombustion.Anunventedroom

heater produces approximately one ounce (30ml) of water for every

1,000BTU's(.3KW's)ofgasinputperhour.

Unvented room heaters are recommended 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dehumidier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.

Space: Includes the room in which you will install heater plus any

adjoining rooms with doorless passageways or ventilation grills

betweentherooms.

1. Determine the volume of the space (length x width x height).

Length x Width x Height =

cu. ft. (volume of

space)

Example: Space size 16 ft. (length) x 10 ft. (width) x 8 ft. (ceiling

height) = 1,280 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills

or openings, add the volume of these rooms to the total volume

of the space.

2. Divide thespacevolume by 50 cubic feet to determine the

maximum BTU/Hr the space can support.

(volume of space) ÷ 50 cu. ft. = (maximum

BTU/Hr the space can support)

Example: 1,280 cu. ft. (volume of space) ÷ 50 cu. ft. = 25.6 or

25,600 (maximum BTU/Hr the space can support)

A test gage connection is located downstream of the gas appliance

pressure regulator for measuring gas pressure. The connection is

a 1/8 inch N.P.T. plugged tapping.
