Determine Installaon Locaon

 The heater must not be installed in a conned

space or unusually ght construcon unless

provisions are provided for adequate combuson

and venlaon air.

 Naonal Fuel Gas Code, ANSI Z223.1/NFPA 54

denes a conned space as a space whose vol-

ume is less than 50 cubic feet per 1,000 BTU per

hour (4.8m³ per kW) of the aggregate input rang

of all appliances installed in that space and an

unconned space as a space whose volume is not

less than 50 cubic feet per 1,000 BTU per hour

(4.8m³ per kW) of the aggregate input rang of all

appliances installed in that space.

 Rooms connecng directly with the space in

which the appliances are installed, through

openings not furnished with doors, are

considered a part of the unconned space.

The following formula can be used to determine the

maximum heat rang for a given unconned space:

BTU/HR=

(All dimensions are in feet.)

For example:

If L1=15.5 , L2=12 , W=12 , H=8 , and there is no

door between the rooms, then for the space to be

considered unconned the maximum rang is:

=52,800 BTU/HR

If there is a door between the 2 rooms then for the

space to be considered unconned the maximum

rang is:

=29,760 BTU/HR

If the appliance rang exceeds the maximum heater

rang in the calculaon above, the space is conned.

(L1+L2) X W X H X 1000

50

(15.5+12) X 12 X 8 X 1000

50

15.5 X 12 X 8 X 1000

50

If the area in which the heater may be operated is

smaller than that dened as an unconned space or if

the building is of unusually ght construcon, provide

adequate combuson and venlaon air by one of

the methods described in the Naonal Fuel Gas Code,

ANSI Z223.1/NFPA 54, Secon 5.3 or applicable local

codes.

WARNING

Unusually ght construcon is dened as construcon

where:

 Walls and ceilings exposed to the outside

atmosphere have a connuous water vapor

retarder with a rang of 1 therm or less with

openings gasketed or sealed;

 Weather stripping has been added on openable

windows and doors; and caulking or sealants are

applied to areas such as joint around window and

door frames, between sole plates and oors,

between wall ceiling joints, between wall panels,

at penetraons for plumbing, and gas lines, and at

other openings.

Clearances

The minimum clearances from combusble materials

and for proper operaon and servicing are as follows:

 2 inches from top

 2 inches from back (measured from the base of

the appliance)

 2 inches from sides

 30 inches from front

 0 inches from boom

In addion, do not install in areas where curtains,

drapes, clothing, or other moving ammables are

within 12 inches of the appliance.
