OPERATION  
This heater is clean burning. It requires no  
outside venting. There is no heat loss out a  
vent or up a chimney. Heat is generated by

SAFETY PILOT  
This heater has a pilot with an Oxygen  
Depletion Sensing (ODS) safety shutoff  
system. The ODS/pilot is a required feature  
for vent-free room heaters. The ODS/pilot  
shuts off the heater if there is not enough  
fresh air.  
PIEZO IGNITION SYSTEM  
This heater has a piezo ignitor. This system  
requires no matches, batteries, or other

VENT-FREE NATURAL GAS STOVE HEATER  
Confined and Unconfined Space  
PROVIDING ADEQUATE  
VENTILATION  
AIR FOR  
The National Fuel Gas Code ANSI Z223.1/  
NFPA 54 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 appli-  
ances installed in that space and an uncon-  
fined 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 input  
rating of all appliances installed in that  
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 Na-  
tional Fuel Gas Code, ANSI Z223.1/  
NFPA 54, Section 5.3, Air for Combus-  
tion and Ventilation.  
WARNING: This heater shall  
not be installed in a confined  
space or unusually tight con-  
struction unless provisions are  
provided for adequate combus-  
tion and ventilation air. Read  
the following instructions to in-  
sure proper fresh air for this  
and other fuel-burning appli-  
ances 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 4 through 6 will  
help you classify your space and provide  
adequate ventilation.  
* Adjoining rooms are communicating only  
iftherearedoorlesspassagewaysorventila-  
tion grills between them.  
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.  
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.  
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 6.  
If your home does not meet all of the  
three criteria above, proceed to De-  
termining Fresh-Air Flow For Heater

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION  
Determining if You Have a Confined or Unconfined Space  
Use this work sheet to determine if you have a confined or unconfined space.  
Space:Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween  
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 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =2560 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 20 to determine the maximum Btu/Hr the space can support.  
_________________ (volume of space) x 20 = (maximum Btu/Hr the space can support)  
Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum Btu/Hr the space can support)  
3. Add the Btu/Hr of all fuel burning appliances in the space.

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: 51,200 Btu/Hr (maximum the space can support)  
70,000 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 cansupport.  
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 adjoin-  
ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.  
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.  
C. Install a lower Btu/Hr heater, 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  
themethodsdescribedintheNationalFuelGasCode,ANSIZ223.1/NFPA54,Section5.3orapplicablelocalcodes.

smell gas, go to the next step.  
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.
