ELECTRIC HEAT CLEARANCE

WARNING

A minimum of 1/4" clearance must be maintained between the supply air duct
and combustible materials. This is required for the first three (3) feet of
ducting.

It is important to insure that the 1/4" minimum spacing is maintained at all
points.

Failure to do this could result in overheating the combustible material which
may result in a fire causing damage, injury, or death.
