WARNING
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.
