COMBUSTION AND VENTILATION AIR

This heater shall not be installed in a conﬁned space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. The heater may be located in unusually tight construction provided the space is unconﬁned, or if conﬁned, is provided with two permanent openings communicating directly with an additional room(s) of sufﬁcient volume so that the combined volume of all connected spaces meets the criteria for an unconﬁned space, (National Fuel Gas Code NFPA 54 / ANSI Z223.1 - latest edition, section on Air for Combustion and Ventilation. Generally 50 ft appliances in the space.

The National Fuel Gas Code, ANSI Z223.1/NFPA 54, deﬁnes a conﬁned space as a space whose volume is less than 50 ft

(4.8 m

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 ft 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 unconﬁned space.

Unusually tight construction is deﬁned as construction where:

a. Wall and ceilings exposed to the outside atmosphere have a continu-

ous water vapor retarder with a rating of one perm (6 X 10-11 kg per pa-sec-m

b. Weather stripping has been added on operable 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.

Use the following equations to determine if you have a conﬁned or unconﬁned space.

per 1,000 BTU/Hr (4.8 m3 per kW) of the aggregate input

) or less with openings gasketed or sealed;

per 1,000 BTU input of all operating

per 1,000 BTU/Hr

Example:

Vent-free heater #1 9,000 BTU/Hr

Vent-free heater #2 23,000 BTU/Hr Gas appliance #1 35,000 BTU/Hr (water heater) Total = 67,000 BTU/Hr

* Do not include direct-vent gas appliances. Direct-vent is sealed com-

bustion and draws combustion air from the outdoors.

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

_______ BTU/Hr (max. the space can support) _______ BTU/Hr (actual amount of BTU/Hr used)

Example: 61,440 BTU/Hr (max. the space can support) 67,000 BTU/Hr (actual amount of BTU/Hr used)

The space in the previous example is a conﬁned space because the actual BTU/Hr used is more than the maximum BTU/Hr the space can support. You must provide additional fresh air.

Your options are:

a. Rework equations adding the space of adjoining room(s). If the extra

volume provides an unconﬁned space, then remove door or add ventilation grills between rooms. Refer to National Fuel Gas Code, ANSI Z223.1/NFPA 54-latest edition, section "Air for Combustion and Ventilation".

b. Vent room directly to the outdoors. Refer to National Fuel Gas Code,

ANSI Z223.1/NFPA 54-latest edition, section "Air for Combustion and

Ventilation".

c. Install a lower BTU/Hr heater to make the area an unconﬁned space.

If the actual BTU/Hr used is less than the maximum BTU/Hr the space can support, then the space is an unconﬁned space. You will need no additional fresh air ventilation for an unconﬁned space.

)/ 50 ft3 =

1. Determine the volume of space — ft

Length x Width x Height = _____ ft (Include adjoining rooms with doorless passageways or ventilation

grills between rooms).

Example: 24' (L) x 16' (W) x 8' (H) = 3072 ft

2. Divide the volume of space by 50 ft3 to determine the maximum BTU/Hr

the space can support.

______ (volume of space – ft (Maximum BTU/Hr the space can support)

Example: 3072 ft or 61,440 BTU/Hr the space can support.

3. Add the BTU/Hr of all the fuel burning appliances in the space.

Vent-Free heater _______ BTU/Hr Gas appliance #1* _______ BTU/Hr Gas appliance #2 + _______ BTU/Hr Gas appliance #3 + _______ BTU/Hr Total = _______ BTU/Hr

/ 50 ft3 = 61.44

WARNING

If the area in which the heater may be operated does not meet the required volume for indoor combustion air, combustion and ventilation air shall be provided by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code or local applicable codes.

WARNING

If the area in which the heater may be operated is smaller than that deﬁned as an unconﬁned space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the national fuel gas code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation Or applicable local codes.
