DESCRIPTION
These compact units employ induced combustion, reliable hot
surface ignition and high heat transfer aluminized tubular heat
exchangers. The units are factory shipped for installation in
upflow or horizontal applications and may be converted for
downflow applications.
These furnaces are designed for residential installation in a
basement, closet, alcove, attic, recreation room or garage and
are also ideal for commercial applications. All units are factory
assembled, wired and tested to assure safe dependable and
economical installation and operation.
These units are Category I listed and may be common vented
with another gas appliance as allowed by the National Fuel Gas
Code.

NOTICE
HORIZONTAL SIDEWALL VENTING
For applications where vertical venting is not possible, the only
approved method of horizontal venting is the use of an auxiliary
power vent. Auxilary power venters must be approved by CSA,
UL, or other recognized safety agencies. Follow all application
and installation details provided by the manufacturer of the
power vent.
FILTER PERFORMANCE
The airflow capacity data published in the “Blower Performance” tables shown represents blower performance WITHOUT filters.
All applications of these furnaces require the use of field
installed air filters. All filter media and mounting hardware or
provisions must be field installed external to the furnace cabinet. DO NOT attempt to install any filters inside the furnace.

1. Air velocity through throwaway type filters may not exceed 300 feet per minute (91.4 m/min). All velocities over this require the use of high velocity filters.
2. Do not exceed 1800 CFM using a single side return and a 16x25 filter. For
CFM greater than 1800, you may use two side returns or one side and the
bottom or one return with a transition to allow use of a 20x25 filter.

Single side return above 1800 CFM is approved as long as
the filter velocity does not exceed filter manufacturer ’s recommendation and a transition is used to allow use on a
