as below.

FRESH AIR FOR COMBUSTION AND

VENTILATION

WARNING

: This heater shall not be installed in a

confined space or unusually tight construction

unless provisions are provided for adequate com-

bustion and ventilation air.  Read the following

instructions to insure proper fresh air for this and

other fuel-burning appliances in your home.

ESTABLISHING ADEQUATE VENTILATION

The following are excerpts from 

National Fuel Gas

Code, NFPA 54/ ANSI 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

This heater must not be installed in a confined space or

unusually tight construction unless provisions are

provided for adequate combustion and ventilation air.

The information on pages 3 through 5 will help you

classify your space and provide adequate ventilation.

Unusually Tight Construction

If your home meets all of the three following criteria you

must provide additional fresh air. See 

Ventilation Air

from Outdoors

, page 4.

Unusually tight construction is defined as construction

where:
a. Walls and ceilings exposed to the outside atmo-

sphere have a continuous water vapor retarder with a

rating of one perm (6 x 10

-11

 kg per pa-sec-m

2

) or less

with openings gasketed or sealed and

b. Whether stripping has been added on openable

windows and doors, and

c. Caulking or sealants are applied to areas such as

joints around windows and door frames, between

wall-ceiling joints, between wall panels, at penetra-

tions for plumbing, electrical, and gas lines, and at

other openings.

If you home does not meet all of the three criteria

above, see 

Determing the Type of Heater Location

Space

, page 3.

Confined Space and Unconfined Space

The

National Fuel Gas Code, NFPA 54/ ANSI Z223.1

defines a confined space as a space whose volume is

less than 50 cubic feet per 1,000 Btu per hour (4.8 m

3

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

3

 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 uncon-

fined space.

*Adjoining rooms are communication only if there are

doorless passageways or ventilation grills between

them.

DETERMINING THE TYPE OF HEATER

LOCATION SPACE:

Use this method to determine if you have a confined or

unconfined space.

Note:

 the space includes the room in which you

install heater plus any adjoining rooms with doorless

passageways or ventilation grills between the

rooms.
