UNVENTED NATURAL GAS LOG HEATER  
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  
unconfined 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 4 through 6 will  
help you classify your space and provide  
adequate ventilation.  
Unusually Tight Construction  
Today’s homes are built more energy  
efficientthanever.Newmaterials,increased  
insulation, and new construction methods  
helpreduceheatlossinhomes.Homeowners  
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 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:  
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  
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.  
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 Deter-  
miningFresh-AirFlowForHeaterLo-  
cation, page 5.

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. 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: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support)  
3. Add the Btu/Hr of all fuel burning appliances in the space.

31,500 Btu/Hr  
71,500 Btu/Hr  
Total  
=
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: 51,200 Btu/Hr (maximum the space can support)  
71,500 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 adjoining  
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  
the methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3 or applicable local codes.

INSTALLING HEATER BASE  
ASSEMBLY  
2. State or local codes do not permit vent-  
free operation  
• approved flexible gas hose (not provided)  
(if allowed by local codes)  
CAUTION: Do not remove the  
metal data plates attached to the  
heater base assembly. The data

information.  
3. You prefer vented operation  
• sealant (resistant to propane/LP gas, not  
provided)  
Ifreasons number 1 or 2 above apply toyou,  
you must permanently open chimney flue  
damper. You must install the damper clamp  
accessory (to order, see Accessories, page  
29). This will insure vented operation (see  
Figure 10). The damper clamp will keep  
damper open. Installation instructions are  
included with clamp accessory.  
• electric drill with 3/16" drill bit (metal  
or masonry as applicable)  
• flathead screwdriver  
WARNING: You must secure  
this heater to fireplace floor. If  
not, heater will move when you  
adjust controls. Moving heater  
may cause a gas leak.  
1. Apply pipe joint sealant lightly to male  
threads of the fitting to be threaded into  
gas regulator. Connect approved flex-  
ible gas hose to gas regulator of heater  
(see Figure 11, page 11).  
See chart below for minimum permanent  
flue opening you must provide. Attach  
damper clamp so the minimum permanent  
flue opening will be maintained at all times.  
IMPORTANT: Hold gas regulator with  
wrench when connecting flexible gas

WARNING: If you do not fol-  
low these instructions exactly, a  
fireorexplosionmayresultcaus-  
ing property damage, personal  
injury or loss of life.  
Note: You may be running this  
heater for the first time after hook-  
ing up to gas supply. If so, the con-  
trol knob may need to be pressed in  
for 30 seconds. This will allow air to  
bleed from the gas system.  
• You must operate this heater  
withafireplacescreeninplace.  
Make sure fireplace screen is  
closed before running heater.  
A. This appliance has a pilot which must  
be lighted by hand. When lighting the  
pilot, follow these instructions exactly.  
6. With control knob pressed in, press  
and release ignitor button. This will  
light pilot. The pilot is attached to the  
burner. If needed, keep pressing ig-  
nitor button until pilot lights.  
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.  
NOTICE: During initial operation  
of new heater, burning logs will  
give off a paper-burning smell.  
Open damper or window to vent  
smell. This will only last a few  
hours.  
Note: If pilot does not light, contact  
a qualified service person or gas sup-  
plier for repairs. Until repairs are  
made, light pilot with match. To light  
pilot with match, see Manual Light-  
ing Procedure on page 15.  
WHAT TO DO IF YOU SMELL  
GAS  
• Do not try to light any appliance.  
Note: Home owners generally prefer to  
operate their heater with the chimney  
damper closed. This will put all the heat  
into the room. However, there may be  
times you will desire the full flames of the  
High heat setting but will find the heat  
output excessive. You can open the chim-  
ney damper (if you have one) fully or  
partially to release some of the heat.  
Do not touch any electric switch; do  
not use any phone in your building.  
7. Keep control knob pressed in for 30  
seconds after lighting pilot. After 30  
seconds, release control knob.  
• Immediately call your gas supplier  
from a neighbor’s phone. Follow  
the gas supplier’s instructions.  
• If you cannot reach your gas sup-  
plier, call the fire department.  
Note: If pilot goes out, repeat steps  
3 through 7.  
• If control knob does not pop out  
when released, contact a qualified  
service person or gas supplier for  
repairs.  
C. Use only your hand to push in or turn  
the gas control knob. Never use tools.  
If the knob will not push in or turn  
by hand, don’t try to repair it, call a  
qualified service technician or gas  
supplier. Force or attempted repair  
may result in a fire or explosion.  
WARNING: Damper handle  
will be hot if heater has been  
running.  
8. Slightly depress and turn control  
knob counterclockwise

vent crimping of capillary. Once you  
have decided on a location, clean the  
area thoroughly. Remove the paper  
backing from the adhesive on back of  
mounting clip. Press the clip into the  
new location so that the thermostat  
sensing bulb will be positioned verti-  
cally with the capillary at the bottom  
(see Figure 34). Slide the thermostat  
sensing bulb into the clip.  
POSITIONING OF  
THERMOSTAT  
SENSING BULB  
If you have a factory-built metal fire-  
place, see Figure 32 for location.  
FOR MASONRY AND  
FACTORY-BUILT METAL  
FIREPLACE  
If your fireplace has glass doors, posi-  
tion sensing bulb directly behind door  
gap on right bottom side (see Figure 33).  
If your log set cycles to pilot, but the room  
temperature drops to a lower than ideal  
comfort level before the log set comes back  
on, you may want to reposition the thermo-  
stat sensing bulb.  
IMPORTANT: Do not crimp capillary.  
Thermostat Sensing Bulb  
The thermostat sensing bulb is located near  
the gas valve assembly on the mounting  
bracket. This location allows the thermostat  
to keep the room temperature at an ideal  
comfort level for most fireplace applica-  
tions. For positioning the thermostat sens-  
ing bulb elsewhere, an adhesive-backed  
mounting clip is available.
