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. Read the following in­structions to insure proper fresh air for this and other fuel-burning appliances in your home.
Today’ s homes are built more ener gy 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 airtight as possible.
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 combustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. This will insure proper venting of vented fuel-burning appliances.
The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFP A 54, Section 5.3, Air for Combustion and Ventilation.
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
The air that leaks around doors and windows may provide enough fresh air for combustion and ven­tilation. However, in buildings of unusually tight construction, you must provide additional fresh air.
110361-01E 5
Unusually tight construction is defined as construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous water vapor retarder with a rating of one perm (6 x 10 or less with openings gasketed or sealed and
b. weather stripping has been added on
openable windows and doors and
c. caulking or sealants are applied to ar-
eas 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 these three crite­ria, you must provide additional fresh air. See
Ventilation Air From Outdoor s
If your home does not meet all of the three criteria above, proceed to
Fresh-Air Flow For Fireplace Location
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a confined space as a space whose vol-
ume 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.
* Adjoining rooms are communicating only if there are doorless passageways or ventilation grills be­tween them.
Determining if You Have a Confined or Unconfined Space
Use this work sheet 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.

, page 7
1. Determine the volume of the space (length x width x height).
Length x Width x Height =__________cu. ft. (volume of space)
(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 = (Maxi-
mum Btu/Hr the space can support)
51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free fireplace __________ Btu/Hr Gas water heater* __________ Btu/Hr Gas furnace __________ Btu/Hr Vented gas heater __________ Btu/Hr Gas fireplace logs __________ Btu/Hr Other gas appliances* + __________ Btu/Hr
Total = __________ Btu/Hr * Do not include direct-vent gas appliances. Di-
rect-vent draws combustion air from the outdoors and vents to the outdoors.
Gas water heater ______________ Btu/Hr Vent-free fireplace ______________ Btu/Hr Total ______________ Btu/Hr
4. Compare the maximum Btu/Hr the space can support with the 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 adjoin-
ing 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 Ventila-
tion Air From Outdoors, page 7.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size
makes room unconfined.
Space size 20 ft. (length) x 16 ft.
2560 cu. ft. (volume of space) x 20 =
30,000 + 26,000 = 56,000

can support) 56,000 Btu/Hr (actual amount of
Btu/Hr used)
6 110361-01E
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an uncon­fined space. Y ou 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
ANSI Z223.1/NFPA 54 Section
Ventilation Air From Inside Building
This fresh air would come from an adjoining un­confined space. When ventilating to an adjoining unconfined space, you must provide two perma­nent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). Y ou can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas
Code, ANS Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of
ventilation grills or ducts.

WARNING: A qualified ser­vice person must connect heater to gas supply. Follow all local codes.
CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2"
diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.
CAUTION: Never connect propane/LP heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the exter­nal regulator between the heater and propane/LP supply.
WARNING: Never connect natural gas heater to private (non­utility) gas wells. This gas is com­monly known as wellhead gas.
Installation Items Needed
Before installing heater, make sure you have the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench * An CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable alterna­tive to test gauge connection. Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 26.
For propane/LP units, the installer must supply an external regulator. The external regulator will re­duce incoming gas pressure. You must reduce in­coming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pres­sure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 6. Pointing the vent down pro­tects it from freezing rain or sleet.
110361-01E 9
Installation must include an equipment 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 7, page 10).
an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.
Check building codes for any special requirements for locating equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from go­ing into pipe. Excess sealant in pipe could result in clogged heater valves.
