see flex duct manufacturer's recommendations for equivalent diameters.
a. For 800 CFM–16-in. round or 14
b. For 1200 CFM–20-in. round or 14
c. For 1600 CFM–22-in. round or 14
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.

control motors, which include a pre-programmed micro-processor-
based control to precisely control the selected airflow rates. The
motor will be referred to as ICM2+ in the rest of this document.
The design of the upflow/horizontal gas-fired furnace is C.S.A.
(A.G.A. and C.G.A.) design-certified for use with natural and
propane gases and for installation on combustible wood flooring,
in alcoves, attics, basements, closets, crawlspaces, or utility rooms.
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.

Application of this furnace should be indoors 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 premature 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
55°F such as when used with a night setback thermostat. Return-air
temperature must not exceed a maximum of 85°F. Failure to
follow these return-air temperature limits may affect reliability of
heat exchangers, motors, and controls. (See Fig. 2.)
