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.
Provisions for Adequate
Combustion and Ventilation Air
Today's homes are built more energy efficient than
ever. New materials, increased insulation and new
construction methods help reduce heat loss in homes.
Home owners weather strip and caulk around windows
and doors to keep the cold air out and the warm air in.
During heating months, home owners want their homes
as air tight as possible.
While it is good to make your home energy efficient,
you need fresh air. All fuel-burning appliances need
fresh air for proper combustion.
Supplying Adequate Ventilation
This appliance must be installed in an unconfined
space.
The National Fuel Gas Code's definitions for confined
and unconfined spaces are as shown below.
The National Fuel Gas Code, ANSI 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
m3 per kw) of the aggregate input rating 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 (4.8 m
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.

Confined or Unconfined Space
volume of these rooms to compute the total volume
of the applicable 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:
= 100 or 100,000 (maximum BTU/Hr the space can
support)
3. Add the BTU/Hr of all gas burning appliances in the
space.
Example:
*Do not include direct-vent gas appliances. Direct-vent
draws combustion air from the outdoors and vents to
the outdoors.
4. Compare the maximum BTU/Hr the space can
support with the actual amount of BTU/Hr used.
_______ BTU/Hr (maximum the space can support)
_______ BTU/Hr (actual amount of BTU/Hr used)
Example:
support) 89,000 BTU/Hr (actual amount of BTU/Hr
used)
The space in the above example is an unconfined
space because the actual BTU/Hr used is less than the
maximum BTU/Hr the space can support. If the space
had been confined, your options would be as follows:
A. Rework worksheet, adding the space of an adjoining
room. If the extra space provides an unconfined
space, remove door to adjoining room or add
ventilation grills between rooms. See Ventilation Air
From Inside Building.
B. Install a lower BTU/Hr heater, if lower BTU/Hr size
makes room unconfined.

Use this worksheet to determine if you have a confined
or unconfined space.
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 25’ (length) x 25’ (width) x 8’
(ceiling height) = 5,000 cu. ft. (volume of space)
If additional ventilation from adjoining room(s) is
supplied with grilles or doorless openings, add the

Converting Confined Space
to Unconfined Space
Additional volume to convert a confined to an unconfined space could come from an adjoining space.
When using an adjoining space, you can provide two
permanent openings: one within 12" of the ceiling and
one within 12" of the floor on the wall connecting the
two spaces (Refer to Options 1 and 3, Figure 1), or
remove the door into the adjoining room.

Ventilation Air from Outdoors for Unusually
Tight Construction
WARNING: 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 tight
construction, provide adequate combustion and
ventilation air by one of the methods described in
the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
Section 5.3 or applicable local codes.
Unusually tight construction is defined as construc-
tion where:
a. walls and ceilings exposed to the outside atmo-
sphere have a continuous water vapor retarder with
a rating of one perm (6x10.
less with openings gasketed or sealed and
b. weather stripping has been added on openable
windows and doors.
c. caulking or sealants are applied to areas such as
joints around window and door frames, between sole
plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing,
electrical and gas lines and at other openings.
If your home meets all of the three criteria above, you
must provide additional fresh air.

You may provide two permanent openings: one within
12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces
open to the outdoors. These spaces include attics and
crawl spaces. Follow the National Fuel Gas Code
NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion
and Ventilation for required size of ventilation grills or
ducts.
IMPORTANT: Do not provide openings for inlet or
outlet air into attic if attic has a thermostat-controlled
power vent. Heated air entering the attic will activate
the power vent.
You may provide two permanent openings: one within
12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces
open to the outdoors. These spaces include attics and
crawl spaces. Follow the National Fuel Gas Code
NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion
and Ventilation for required size of ventilation grills or
ducts.
WARNING: Air openings that provide fresh air
from an adjoining unconfined space shall not be
blocked or obstructed in any way. Installation of
unit should allow a minimum of 2” clearance
from any part of the heater to any of the ventilation openings.
