SAFETY DEVICE

This unit has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff sys tem. The ODS/pilot shuts off the appliance if there is not enough fresh air.

PIEZO IGNITION SYSTEM

This unit has a piezo ignitor. This system requires no matches, batteries, or other sourc es to light appliance.

AIR FOR COMBUSTION AND VENTILATION

W ARNING: This appliance shall not be installed in a conﬁ ned space or unusually tight con struc tion un less pro vi sions are pro vid ed for ad e quate com bus tion and ven ti la tion air. Read the fol low ing in struc tions to in sure prop er fresh air for this and other fuel-burning ap pli anc es in your home.

Today’s homes are built more energy ef ﬁ cient than ever. New ma te ri als, increased in su la tion, 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 owners want their homes as airtight as pos si ble.

While it is good to make your home energy efﬁ cient, your home needs to breathe. Fresh air must enter your home. All fuel-b urning appliances need fresh air for proper com bus tion and ven ti la tion.

Exhaust fans, ﬁ replaces, clothes dryers, and fuel burning appliances draw air from the house to operate. Y ou must provide ad e quate fresh air for these ap pli anc es. This will insure proper venting of vented fuel-burning appliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, Sec tion 5.3, Air for Combustion and Ven ti la tion.

All spaces in homes fall into one of the three following ventilation classiﬁ cations:

1. Unusually Tight Construction

2. Unconﬁ ned Space

3. Conﬁ ned Space The information on pages 4 through 6 will help you classify your

space and provide ad e quate ven ti la tion.

Unusually Tight Construction

The air that leaks around doors and win dows may provide enough fresh air for combustion and ventilation. Howe ver, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is de ﬁ ned as construction where:

a. walls and ceilings exposed to the outside at mo sphere

have a con tin u ous water vapor retarder with a rating of one perm (6 x 10 open ings gasketed or sealed and

b. weather stripping has been add ed on openable win-

dows and doors and

c. caulking or sealants are applied to areas such as

joints around window and door frames, be tween sole plates and ﬂ oors, be tween wall-ceiling joints, be tween wall panels, at pen e tra tions for plumb ing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you

must pro vide ad di tion al fresh air . See Ventilation Air From Outdoors, page 5.

If your home does not meet all of the three criteria above, proceed to De ter min ing Fresh-Air Flow For Appliance Lo ca tion, below.

Conﬁ ned and Unconﬁ ned Space

The National Fuel Gas Code, ANSI Z223.1/NFPA 54 deﬁ nes a con ﬁ ned 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 ag gre gate input rating of all ap pli anc es in stalled in that space and an un con ﬁ ned space as a space whose vol ume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the ag gre gate input rating of all appliances in stalled in that space. Rooms com mu ni cat ing di rect ly with the space in which the ap pli anc es are in stalled*, through openings not fur nished with doors, are con sid ered a part of the unconﬁ ned space.

* Adjoining rooms are communicating only if there are doorless passageways or ven ti la tion grills between them.

DETERMINING FRESH-AIR FLOW FOR APPLIANCE LOCATION

Determining if You Have a Conﬁ ned or Unconﬁ ned Space

Use this work sheet to determine if you have a conﬁ ned or un con ﬁ ned 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. (vol ume of space) Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceil ing

height) = 2560 cu. ft. (vol ume of space)

If additional ventilation to adjoining room is supplied with grills or open-

ings, add the volume of these rooms to the total vol ume 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 sup port)

Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (max i mum

Btu/Hr the space can sup port)

3. Add the Btu/Hr of all fuel burning ap pli anc es in the space.

Vent-free appliance _____________ Btu/Hr Gas wa ter appliance* _____________ Btu/Hr Gas fur nace _____________ Btu/Hr Vented gas appliance _____________ Btu/Hr Gas ﬁ re place logs _____________ Btu/Hr Other gas appliances* + _____________ Btu/Hr Total = _____________ Btu/Hr

* Do not include direct-vent gas ap pli anc es. Direct-vent draws com-

bus tion air from the outdoors and vents to the outdoors.

Example: Gas water appliance _____________ Btu/Hr Vent-free appliance + _____________ Btu/Hr Total = _____________ Btu/Hr

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

____________________Btu/Hr (maximum the space can sup port) ____________________Btu/Hr (actual amount of Btu/Hr used) Example: 51,200 Btu/Hr (max i mum the space can support) 73,000 Btu/Hr (actual amount of Btu/Hr used) The space in the above example is a con ﬁ ned space because the actual

Btu/Hr used is more than the maximum Btu/Hr the space can sup port. Y ou must provide additional fresh air. Your op tions are as follows:

A. Rework worksheet, adding the space of an adjoining room. If the ex tra

space provides an unconﬁ ned space, remove door to ad join ing room or add ven ti la tion grills between rooms. See Ven ti la tion Air From Inside Building, page 6.

B. V ent room directly to the outdoors. See V entilation Air F rom Out doors,

page 6.

C. Install a lower Btu/Hr appliance, if lower Btu/Hr size makes room un con -

ﬁ ned.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can sup port, the space is an unconﬁ ned space. You will need no additional fresh air ven ti la tion.

40,000 33,000 73,000

WARNING: If the area in which the appliance may be operated is smaller than that deﬁ ned as an un con ﬁ ned space or if the building is of unusually tight construction, pro vide ad e quate com bus tion and ven ti la tion air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 Sec tion 5.3 or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconﬁ ned space. When ventilating to an adjoining unconﬁ ned space, you must pro vide two permanent open ings: one within 12" of the ceiling and one within 12" of the ﬂ oor on the wall con nect ing the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see op tion 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two per ma nent open ings: one within 12" of the ceiling and one within 12" of the ﬂ oor. Connect these items directly to
