MIS-277

• A minimum of 1/4 inch clearance must be maintained between

the supply air duct and combustible materials.  This is required
for the first 3 feet of ducting.

• It is important to insure that the 1/4 inch minimum spacing is

maintained at all points.

• Failure to do this could result in overheating the combustible

material and may result in fire.
