UNVENTED PROPANE/LP 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.  
Today’s homes are built more energy effi-  
cient than ever. New materials, increased  
insulation, and new construction methods  
help reduce heat loss in homes. Home own-  
ers weather strip and caulk around windows  
and doors to keep the cold air out and the  
warm air in. During heating months, home  
ownerswanttheirhomesasairtightaspossible.  
Unusually Tight Construction  
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 (6x10-11 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. 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.

* 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)  
79,000 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  
the methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3 or applicable local codes.

Continued  
nally-tinned copper tubing may  
be used in certain areas. Check  
yourlocalcodes.Usepipeof1/2"  
diameter or greater to allow  
proper gas volume to heater. If  
pipe is too small, undue loss of  
pressure will occur.  
NOTICE: A qualified service per-  
son must connect heater to gas  
supply. Follow all local codes.  
5. Center heater base and logs front-to-  
back and side-to-side in fireplace.  
6. Carefully remove logs without moving  
heater base.  
CAUTION: Never connect  
heaterdirectlytothepropanesup-  
ply. This heater requires an exter-  
nalregulator(notsupplied).Install  
theexternalregulatorbetweenthe  
heater and propane supply.  
7. Mark screw locations through one hole  
on each side of the mounting bracket  
(see Figure 12). If installing in a brick-  
bottom fireplace, mark screw locations  
in mortar joint of bricks.  
Installation must include a manual shutoff  
valve, union, and plugged 1/8" NPT tap.  
Locate NPT tap within reach for test gauge  
hook up. NPT tap must be upstream from  
heater (see Figure 14, page 12).  
8. Remove heater base from fireplace. If  
installing optional control accessories,  
do so at this time. Follow all directions  
provided with accessory.  
Installation Items Needed  
Apply pipe joint sealant lightly to male  
threads. This will prevent excess sealant  
from going into pipe. Excess sealant in pipe  
could result in clogged heater valves.  
Beforeinstallingheater,makesureyouhave  
the items listed below.  
9. Drill holes at marked locations using  
3/16" drill bit.  
• external regulator (supplied by installer,  
see above)  
10. Attach base assembly to fireplace floor  
using two masonry screws (in hardware  
package).  
• piping (check local codes)  
• sealant (resistant to LP gas)  
• manual shutoff valve *  
• test gauge connection *  
• sediment trap  
CAUTION:Usepipejointseal-

11. Connect to gas supply. See Connect-  
ing To Gas Supply.  
12. Replace logs on heater base.  
Installsedimenttrapinsupplylineasshown  
in Figure 14, page 12. Locate sediment trap  
where it is within reach for cleaning. Locate  
sediment trap where trapped matter is not  
likely to freeze. A sediment trap traps mois-  
ture and contaminants. This keeps them  
from going into heater controls. If sediment  
trap is not installed or is installed wrong,  
heater may not run properly.

Fitting  
The installer must supply an external regu-  
lator. The external regulator will reduce  
incoming gas pressure. You must reduce  
incominggaspressuretobetween11and14  
inches of water. If you do not reduce incom-  
ing gas pressure, heater regulator damage  
could occur. Install external regulator with  
the vent pointing down as shown in Figure  
13. Pointing the vent down protects it from  
freezing rain or sleet.  
CAUTION: Avoid damage to  
control. Hold fitting with wrench
