AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a confined space or unusually tight construc- tion unless provisions are provided for adequate combustion and ven- tilation air. Read the following in- structions to insure proper fresh air for this and other fuel-burning appliances in your home.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code, NFPA 54/ ANSZ 223.1.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 5 will help you classify your space and provide adequate ventilation.

Confined and Unconfined Space

The National Fuel Gas Code, ANS 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 m3 per kw) of the ag- gregate input rating of all appliances installed in that space and an unconfining 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 in- stalled in that space. Rooms com- municating directly with the space in which the appliances are installed*, through openings not furnished with doors, are consid- ered a part of the unconfined space.

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.

*Adjoining rooms are communi- cating only if there are doorless passageways or ventilation grills between them.

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 ( 6×10-11kg per pa-sec-m2) or less with openings gasketed or sealed and

b)weather stripping has been added on windows that open and doors and

c)caulking or sealants are ap- plied 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 pro-

vide additional fresh air. See Ven- tilation Air From Outdoors, page 5. If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow For Heater Location, below.

DETERMINING FRESH AIR FLOW FOR HEATER LOCATION

Determining if

You Have a Confined or Unconfined Space

 

Use this worksheet to determine if you have a confined or unconfined space.

 

Space: Includes

the room in which you will install

heater plus any

adjoining rooms with doorless

passageways

or ventilation

grills between

the rooms.

1. Determine

the

volume of

the space (length width height).

cu.ft. (volume of space)

Example: Space size 20ft. (length) 16ft. ( width)

8ft. (ceiling height)=2560 cu. ft. (volume of space)

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: 2560 cu. ft. (volume of space)÷50 cu.ft.=51.2 or 51,200(maximum Btu/Hr the space can support)
