1. Extremely long runs and numerous turns in the duct leading from the fireplace to the combustion air
assembly should be avoided. These conditions will increase the resistance to the free flow of air through
the duct. Refer to Figures 1, 21, and 22 for methods of installing the outside air for combustion assemblies.
2. The combustion air assembly should be located at an exterior location, which is not likely to be accidentally
blocked in any manner. The assembly should be located above the snow line to prevent blockage by snow
accumulation.
3. The combustion air inlet assembly should never be mounted in a garage or storage area where combustible
fumes such as gasoline might be drawn into the fireplace.
4. Combustion air can be drawn form the crawl space under a house when an adequate supply of air is
provided by open ventilation.
5. Do not take combustion air from attic space or garage space.
