WARNING ICONG 001WARNING

 

 

 

 

 

 

FOR

 

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

 

 

 

COMBUSTION

 

fuel combustion could result. Read the following instructions to

 

 

 

 

insure proper fresh air for this and other fuel-burning appliances

 

 

 

AND

 

 

 

 

 

in your home.

 

 

 

 

 

 

VENTILATION

 

 

 

 

 

 

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 fuel-burning appliances.

 

 

 

 

 

 

 

 

PRODUCING ADEQUATE 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 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 continu-

 

 

 

 

 

ous water vapor retarder with a rating of one perm or less with open-

 

 

 

 

 

ings gasketed or sealed and

 

 

 

 

 

 

 

 

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, 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 addi-

 

 

 

 

 

tional fresh air. See Ventilation Air From Outdoors, page 8.

 

 

 

 

 

 

 

 

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

 

 

 

 

 

Unconfined Space

 

 

 

 

 

 

 

 

An unconfined space has a minimum air volume of 50 cubic feet for each 1000

 

 

 

 

 

BTU/Hr input rating of all appliances in the space (cubic feet equals length x

 

 

 

 

 

width x height of space). Include adjoining rooms only if there are doorless

 

 

 

 

 

passageways or ventilation grills between the rooms.

 

 

 

 

 

 

 

 

Confined Space

 

 

 

 

 

 

 

 

A confined space has an air volume of less than 50 cubic feet for each 1000

 

 

 

 

 

BTU/Hr input rating of all appliances in the space (cubic feet equals length x

 

 

 

 

 

width x height of space). Include adjoining rooms only if there are doorless

 

 

 

 

 

passageways or ventilation grills between the rooms.
