- Combustion Air Required (Indoor Installations)240FX
In order to ensure an adequate supply of combustion air, the
National Fuel Gas Code requires that any conventional vented gas appliance be
installed in a room with a minimum volume of 50 cubic feet per 1,000 Btu/hr
rated input. The following is the minimum size of the open space in which the
240FX may be installed in compliance with this requirement:
| Model |
Volume |
Area with an 8' ceiling |
| 240FX |
8,250 cubic feet |
1,031 square feet |
If the 240FX is installed in an area smaller than indicated
above, then the installer must make special provisions for combustion air in the
form of two openings, each one within 12" of the top and 12" of the
bottom of the space, having a total free area of 1 square inch per 1,000 Btu/hr
of rated input if the air is taken from inside the house (two 13" x
13" openings). This requirement reduces to 1 square inch per 4,000 Btu/hr
if the air is taken from the outside (two 6.5" x 6.5" openings).
Note: This calculation assumes normal rates of
"infiltration" of outside air. A super-insulated, super-tight
space/building may require outside air for the 240FX even though the volume/area
of the space meets this application.
Caution: In addition to the above, the 240FX must be
properly vented to ensure safe and efficient operation.
