The design of this furnace line is not C.S.A. (A.G.A. and C.G.A.)
design-certified for installation in mobile homes, recreation ve-
hicles, or outdoors.
These instructions cover minimum requirements and conform to
existing national standards and safety codes. In some instances,
these instructions exceed certain local codes and ordinances,
especially those that may not have kept up with changing residen-
tial construction practices. We require these instructions as a
minimum for a safe installation.
CAUTION: Application of this furnace should be in-
doors with special attention given to vent sizing and
material, gas input rate, air temperature rise, and unit
sizing. Improper installation or misapplication of the
furnace can require excessive servicing or cause prema-
ture component failure.
To aid in installation, troubleshooting, and service, a status code
label is located on the blower compartment door. This label
explains how to use the LED status indicator on the furnace control
which is viewed through the sight glass on the door.
NOTE: These furnaces are designed for a minimum continuous
return-air temperature of 60°F or intermittent operation down to

d. For airflow requirements above 1800 CFM, see Air Delivery table in Product Data literature for specific
use of single side inlets. The use of both side inlets, a combination of 1 side and the bottom, or the
bottom only will ensure adequate return air openings for airflow requirements above 1800 CFM.
