Clearances Needed for Furnaces

APPLIES TO: All Models
When installing your outdoor furnace, it is good to know the following clearance distances from combustibles. The first thing you should always do is consult your homeowner's insurance company. Insurance companies have different rules and regulations. Also, check out any zoning laws in your area. Obtaining this information will help in deciding the proper location and distances from combustibles for your furnace installation.

Maintain the following clearances from combustibles for the furnace installation:
  • 44" (112 cm) from the back
  • 12" (30.5 cm) from the sides
  • 48" (122 cm) from the front
  • 18" (46 cm) from chimney inspection cover

NOTE: The foundation must be noncombustible.

Do not allow combustible materials (straw, hay, or wood) near the outdoor furnace. Keep the perimeter of the outdoor furnace clear and clean.

For fire safety, keep all combustible materials at least six feet (two meters) away from the outdoor furnace, especially around the door area. Debris of wood chips and other combustibles in the area may be easily ignited if a hot coal is spilled out of the firebox and left unnoticed.

Please refer to your Owner's Manual for recommended maintenance clearances.
