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 a fire causing damage, injury or death.
