FURNACE RELIABILITY HAZARD

Failure to follow this caution may result in unit damage.

Improper installation or misapplication of furnace may

require excessive servicing or cause premature component

failure. This furnace can be vented as either a direct vent

(2- -pipe) furnace or as an optional ventilated combustion air

Application.

A direct vent system shall be installed in accordance with

the direct vent (2- -pipe) procedures in the Combustion Air

and Vent Pipe Systems section within this instruction. For

optional ventilated combustion air applications, refer to the

ventilated combustion air option procedures in the same

section.

Application of this furnace should be indoors with special

attention given to vent sizing and material, gas input rate,

air temperature rise, unit leveling, and unit sizing.
