VF/VFR Vent-Free Fireboxes

COMBUSTION AIR

1. Locate combustion air assembly at an exterior location

which is not likely to be accidentally blocked in any man-

ner. Locate assembly a min. of 1" above the snow line

to prevent blockage by snow accumulation.

. Never mount the combustion air inlet assembly in a

garage or storage area where combustible fumes such

as gasoline might be drawn into the fireplace.

3. Combustion air can be drawn from the crawl space un-

der a house when an adequate supply of air is provided

by open ventilation.

4. CAUTION: Do not take combustion air from attic

space or garage space.

Locate air supply inlet at least 3' away from any ap-

pliance vent terminal.

6. Avoid extremely long runs and numerous turns in the

duct leading from the fireplace to the combustion air

assembly. These conditions increase the resistance to

the free flow of air through the duct. Refer to Figures

12 through 15 for methods of installing the outside air

for combustion assemblies.
