INTRODUCTION
Use this instruction manual to install indoor coil on multipoise furnaces. The indoor coil is enclosed
in a casing.
For oil and gas furnaces, the indoor coil should be installed on the supply side of the furnace. A
spacer of a minimum of 4'' shall be provided between the furnace and the coil to prevent damage
to the drain pan by the heat exchanger. It will also ensure a proper air flow through the coil.
For electric furnaces and air handler the indoor coil should be installed on the return side of the
air handler.
When installing a wider coil on a narrower furnace or air handler, a transition must be installed.
Factory made transitions are available for the Chinook, Supreme & Unique furnaces and Duotec
AHV air handlers. These transitions are specially designed to fit those furnaces and ensure a
perfect fit of the installation.
