ELECTRIC HEAT CLEARANCE

Side section view of supply air duct for wall mounted unit showing 1/4 inch clearance to combustible surfaces.

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 fire.
