Radiance Vent-Free Gas Heater

2.Divide the volume of space by 50 cubic feet. The result is the maximum BTU/Hr that the space can sup- port.

Example:

3840 divided by 50 = 76.8 or 76,800 BTU/Hr.

3.Add the BTU/Hr ratings of all fuel-burning appliances installed in the same space, including the following:

Gas Water Heater

Gas Furnace

Gas Fireplace Logs

Unvented Gas Heater

Vented Gas Heater*

Other Gas Appliances*

*Do not include Direct Vent appliances as these utilize outside air for combustion and vent to the outdoors.

 

 

Example:

Gas Range

55,000 BTU/Hr

Unvented Heater

+33,000

BTU/Hr

Total

88,000

BTU/Hr

Each of the two grilles must provide an opening of at least 50 square inches, with all opening dimensions being at least 3”. One grille must be located within 12” of the ceiling; the other within 12” of the floor. (If the total exceeds 100,000 BTU/Hr, additional grilles will be required.)

B)Vent the room directly to the outdoors. (Provide one square inch of opening for each 4,000 BTU/hr.

If the total BTU/Hr used by the appliances is less than the maximum BTU/Hr the space is able to support, the room meets the Unconfined space criteria and no further ventilation is required.

For further information on ventilation guidelines and sizing specifications follow the National Fuel Gas Code NFPA 54/ANSI Z223.1 Section 5.3.

4.Compare the maximum BTU/Hr rating the space can support with the total BTU/Hr used by the appliances.

Example:

76,800 BTU/Hr - max. the space can support

88,000 BTU/Hr - total used by appliances

In this example, the maximum BTU/Hr that the space can support is less than the total used by the appli- ances, the space is considered to be Confined space. Additional air must be provided to meet the require- ments of the Unvented heater.

A confined space may be ventilated in two ways:

A)Open up or provide at least two ventilating grilles to an adjoining unconfined space. Use any of the options illustrated in Figure 4.

This heater shall not be installed in a confined space unless provisions are made for adequate combustion and ventilation air.

If the area in which the heater may be operated is smaller than that defined as an unconfined space, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1, 1992 Section 5.3.
