OWNER’S MANUAL
Confined and Unconfined Space
PROVIDING ADEQUATE
VENTILATION
AIR FOR
The National Fuel Gas Code (ANS Z223.1,
1992 Section 5.3) 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
unconfining space as a space whose volume
is not less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3 per kw) of the aggregate
inputratingofallappliancesinstalledinthat
space. Rooms communicating directly with
the space in which the appliances are in-
stalled*, through openings not furnished
with doors, are considered a part of the
unconfined space.
COMBUSTION AND
VENTILATION
The following are excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-
tion5.3, AirforCombustionandVentilation.
WARNING: This heater shall
notbeinstalledinaconfinedspace
or unusually tight construction
unless provisions are provided
foradequatecombustionandven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through 7 will
help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weather strip and caulk around windows and
doorstokeepthecoldairoutandthewarmair
in. During heating months, home owners
want their homes as airtight as possible.
This heater shall not be installed in a con-
fined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
The air that leaks around doors and win-
dows may provide enough fresh air for
combustion and ventilation. However, in
buildings of unusually tight construction,
you must provide additional fresh air.
* Adjoining rooms are communicating only
iftherearedoorlesspassagewaysorventila-
tion grills between them.
Unusually tight construction is de-
fined as construction where:
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
a. walls and ceilings exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one perm (6 x 10-11 kg
per pa-sec-m2) or less with open-
ings gasketed or sealed and
Exhaustfans, fireplaces, clothesdryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
b. weather stripping has been
added on openable windows and
doors and
c. caulking or sealants are applied
to areas such as joints around
window and door frames, be-
tween sole plates and floors, be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tions for plumbing, electrical, and
gas lines, and at other openings.
If your home meets all of the three
criteria above, you must provide ad-
ditional fresh air. See Ventilation Air
From Outdoors, page 7.
If your home does not meet all of the
three criteria above, proceed to De-
termining Fresh-Air Flow For Fire-
place Location, page 6.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install fireplace 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 14 ft. (width) x 8 ft. (ceiling height) = 1792 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. Multiply the space volume by 1000 Btu/Hr per 50 cubic feet to determine the maximum Btu/Hr the space can support.
_____________________(volume of space) x (1000 Btu/Hr ÷ 50 cu. ft.) = (Maximum Btu/Hr the space can support)
Example: 1792 cu. ft. (space volume) x (1000 Btu/Hr ÷ 50 cu. ft.) = 35,840 Btu/Hr. This is the maximum Btu/Hr the space can
support.
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free fireplace
Gas water heater*
Gas furnace
______________________ Btu/Hr
______________________ Btu/Hr
______________________ Btu/Hr
______________________ Btu/Hr
______________________ Btu/Hr
Example:
Gas water heater
Vent-free fireplace + 10,000 Btu/Hr
Total 40,000 Btu/Hr
30,000 Btu/Hr
Vented gas heater
Gas fireplace logs
=
Other gas appliances* + ______________________ Btu/Hr
Total = ______________________ Btu/Hr
* 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: 35,840 Btu/Hr (maximum the space can support)
40,000 Btu/Hr (actual amount of Btu/Hr used)
The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.
You must provide additional fresh air. Your options are 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, page 7.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.
C. Install a lower Btu/Hr fireplace, if lower Btu/Hr size makes room unconfined.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no
additional fresh air ventilation.
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, ANS Z223.1, 1992, Section 5.3 or applicable local codes.

pilot, follow these instructions exactly.
Note: If pilot does not stay lit, refer
to Troubleshooting, pages 20 through

Until repairs are made, light pilot with
match. To light pilot with match, see
Manual Lighting Procedure, page 18.
B. BEFORE LIGHTING smell all
around the appliance area for gas. Be
sure to smell next to the floor because
some gas is heavier than air and will
settle on the floor.

several minutes before the blower turns

The blower will shut off after the firebox
temperature decreases.
The thermostat used on this fireplace
senses the room temperature. At times
the room may exceed the set tempera-
ture. If so, the burner will shut off. The
burner will cycle back on when room
temperature drops below the set tem-
perature.
The control knob can be set to any heat
level between HI and LO.
Note: It is safe to operate fireplace with
blower turned off. However, the blower
helps distribute heated air from the
fireplace.
Note: The thermostat sensing bulb mea-
sures the temperature of air near the
fireplace cabinet. This may not always
agree with room temperature (depend-
ing on housing construction, installation
location, room size, open air tempera-
tures, etc.). Frequent use of your fire-
place will let you determine your own
comfort levels.
