Manual backgroundWARNING

Improper installation of the furnace can result in per- sonal injury or death. Combustion and flue products must never be allowed to enter the return air system or the living space. Use screws and joint tape to seal the return air system to the furnace.

In platform installations with bottom return air, the furnace should be sealed airtight to the return air ple- num. A door must never be used as a portion of the return air duct system. The base must provide a stable support and an airtight seal to the furnace. Al- low absolutely no sagging, cracks, gaps, etc.

The return and supply air duct systems must never be connected to or from other heating devices such as a fireplace or stove, etc. Fire, explosion, carbon monoxide poisoning, personal injury and/or proper- ty damage could result.
