DetermineInstallaonLocaon
 The heater must not be installed in a confined
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
defines a confined 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
unconfined 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 unconfined space.
The following formula can be used to determine the
maximum heat rang for a given unconfined 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 unconfined 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 unconfined 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 confined.
(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

If the area in which the heater may be operated is
smaller than that defined as an unconfined 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 defined 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 floors,
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 flammables are
within 12 inches of the appliance.
