AIR FOR COMBUSTION AND VENTILATION
WARNING: This appliance 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 energy 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 fuel­burning appliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code. NFPA 54/ANS Z223.1, 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 4 through 6 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.
Unusually tight construction is de­fined as construction where:
a. walls and ceilings exposed to the
outside atmosphere have a con­tinuous water vapor retarder with a rating of one perm (6x10 per pa-sec-m2) or less with open­ings gasketed or sealed
b. weather stripping has been
added on openable windows and doors
c. caulking or sealants are applied
to areas 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 the three criteria above, you must provide ad­ditional fresh air. See
From Outdoors
If your home does not meet all of the three criteria above, proceed to

Confined and Unconfined Space
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 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.
This log set shall not be installed in a con­fined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.
* Adjoining rooms are communicating only if there are doorless passageways or ventila­tion grills between them.

DETERMINING FRESH-AIR FLOW FOR APPLIANCE 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: Includes the room in which you will install appliance 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:
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:
3. Add the Btu/Hr of all fuel burning appliances in the space. Gas fireplace logs _____________ Btu/Hr
Gas water heater* _____________ Btu/Hr Gas furnace _____________ Btu/Hr Vented gas heater _____________ Btu/Hr Vent-free heater _____________ Btu/Hr 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:
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 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.
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)
2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support)
Example:
Gas water heater 40,000 Btu/Hr Gas fireplace logs + 55,000 Btu/Hr Total = 95,000 Btu/Hr
51,200 Btu/Hr (maximum the space can support) 95,000 Btu/Hr (actual amount of Btu/Hr used)
WARNING: If the area in which the appliance 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
901048
National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3

VENTILATION AIR
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). You can also remove door into adjoining room (see op­tion 3, Figure 2). Follow the National Fuel
Gas Code NFPA 54/ANS Z223.1, Section
5.3, Air for Combustion and Ventilation for
required size of ventilation grills or ducts.
WARNING: Rework work­sheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two per­manent openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces.
IMPORTANT:
inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent.

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 log set. If pipe is too small, undue loss of pressure will occur.
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 log set (see Figure 6).
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in a clogged burner injector.
CAUTION: Use pipe joint seal­ant that is resistant to liquid pe­troleum (LP) gas.
Install sediment trap in supply line as shown in Figure 6. 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 moisture and contaminants. This keeps them from going into log set controls. If sediment trap is not installed or is installed wrong, log set may not run properly.
Approved Flexible Gas Hose (if allowed by local codes)
CHECKING GAS CONNECTIONS
WARNING: Test all gas pip­ing and connections for leaks after installing or servicing. Cor­rect all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG
1. Disconnect log set and its individual manual shutoff valve from gas supply piping system.
2. Cap off open end of gas pipe where manual shutoff valve was connected.
3. Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.
4. Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles form­ing show a leak.
5. Correct all leaks at once.
6. Reconnect log set and manual shutoff valve to gas supply . Check reconnected fittings for leaks.
