COMBUSTION AND VENTILATION PROVISIONS

WARNING: This heater shall not be installed in a confined space or unusually tight construction

unless provisions are provided for adequate combustion and ventilation air.

Confined Space and Unconfined Space

The National Fuel Gas Code, 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 m³ 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 m³ 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 unconfined space.

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, Section 5.3 or applicable local codes.

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 1 perm (6 x10-11 kg per pa-sec-m²) or less with openings gasketed or sealed,
and

b. Weather stripping has been added to 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 joists, between wall panels, at
penetrations for plumbing, electrical, and gas lines, and at other openings.

Instructions for determining maximum Btu's for a room
Step 1

This calculation is for combustion and ventilation air provisions only and is not intended to be used
for sizing for heating comfort. To determine the maximum Btu's allowed for a given room size you
will need to calculate the volume of the room in cubic feet. To perform this calculation, fill in the
table below and multiply the room's width, length and height to obtain the room volume in cubic feet.

ROOM ROOM ROOM ROOM VOLUME

LENGTH WIDTH HEIGHT IN CUBIC FEET

X X =

Example: If your room is 20 feet in length, 16 feet wide and has an 8 foot ceiling height, the calculation

would be as follows: 20 x 16 x 8 = 2,560 cubic feet.

Step 2

Divide the room volume by 50 cubic feet to determine the maximum Btu per hour the room can utilize.

Example: Using the above example: 2,560 cubic feet divided by 50 = 51.2 x 1,000 = 51,200 Btu's.

If the rate of your appliance plus any other gas appliances installed in the space is rated at more Btu's than the
example calculated above, you must follow instructions for confined space. See shaded WARNING above.
If your appliance is rated at less Btu's than the example calculated above, then your area is considered
unconfined space.
