AIR FOR COMBUSTION AND VENTILATION
CONTINUED
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent
openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items
directly to the outdoors or spaces open to the outdoors. These spaces include attics and
crawl spaces. (See Figure 2)
IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-
controlled power vent. Heated air entering the attic will activate the power vent.
WARNING
Maintain the minimum clearances. If you can, provide greater clearances from
floor, ceiling, and adjoining wall.
INSTALLATION CLEARANCES
Carefully follow the instructions below. This will ensure safe installation.
Minimum Wall and Ceiling Clearances (see Figure 3)
A. Clearances from the side of the firebox opening to any combustible wall should not
be less than 6 inches. (This applies to built-in installation or using an (optional) cabinet
mantel kit.)
B. Clearances from the top of the firebox opening to the ceiling should not be less than
42 inches.
