AIR

FOR

COMBUSTION

AND

VENTILATION

WARNING

This heater must have fresh air for proper operation. If not, poor

fuel combustion could result. 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

insulauon, 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 fue!-bummg appliances need fresh air for proper

combustion and ventilation•

Exhaustfans, 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 iusure proper venting of vented fuel-burning appliances.

PROVIDING ADEQUATE VENTILATION

The following is exerpted from National Fuel Gas Code, NFPA 54/ANSI Z223.1,

• w .... n

Section 5.3, Azr for Combustion and Ventilation .

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

1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.

The information on pages 5 through 8 will help you classify your spa_:eand 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 fight cousWactiou,

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 or less

with openings gasketed or sealed and

b. weather stripping has been added on openahle windows and

doors and

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 Ventilation Air From Outdoors, page 8. If your

home does not meet all of the three criteria above, continue reading.

Confined Space and Unconfined Space

This heater shall not he iustalled in a toni'meal space unless provisions _e provided for

adequate ct)ulbustion mid ventilation air.

The National Fuel Gas Code delines a conlincxl space its a space whose volume is less

than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) ol lilt2 aggregate input rating

WARNING

If the area in which the heater may be operated is smaller

than that defined as an unconfined space, provide

adequate combustion and ventilation air by one of the

methods described in the National Fuel Gas Code, ANSI

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 uncon fined space, you must prbvide two permanent openings: one _¢ithin 12" of the

ceiling and one within 12" of the floor on the wall connecting the two spaces (see options l 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/ANSI Z223.1, Section 5.3, "Air

for Combustion and Ventilation" for required size of ventilation grills or ducts.

•WARNING

Rework worksheet, adding thespace of the adjoining unconfined

space. The combined spaces must have enough fresh air to supply all

appliances in both spaces.
