DESCRIPTION

These Category IV, highly efficient, compact, condensing
type furnaces are designed for residential and commercial
installations in a basement, closet, alcove, recreation room or
garage where the ambient temperature is above 32°F, or
higher. They may be either side wall or thru-roof vented using
approved plastic type combustion air and vent piping. All
units are factory assembled, wired and tested to assure
dependable and economical installation and operation.

WARRANTY

Lifetime limited warranty on both heat exchangers to the orig­inal purchaser; a 20-year limited warranty from original instal­lation date to subsequent purchaser.

10-year warranty on the heat exchanger in commercial appli­cations.

5-year limited parts warranty.

All CFM’s are shown at 0.5” w.c. external static pressure.These units have variable speed motors that automatically adjust to provide constant CFM from 0.0” to 0.6” w.c.
static pressure. From 0.6” to 1.0” static pressure, CFM is reduced by 2% per 0.1” increase in static. Operation on duct systems with greater than 1.0” w.c. external static
pressure is not recommended.
NOTE: At some settings, LOW COOL airflow may be lower that what is required to operate an airflow switch on certain models of electronic air cleaners. Consult the
instructions for the electronic air cleaner for further details.

FILTER PERFORMANCE

FILTER SIZES

The airflow capacity data published in the “Blower Perfor­mance” table listed above represents blower performance
WITHOUT filters. To determine the approximate blower per­formance of the system, apply the filter drop value for the fil­ter being used or select an appropriate value from the “Filter
Performance” table shown.

NOTE: The filter pressure drop values in the “Filter Perfor­mance” table shown are typical values for the type of filter

APPLYING FILTER PRESSURE DROP TO
DETERMINE SYSTEM AIRFLOW

To determine the approximate airflow of the unit with a filter in
place, follow the steps below:

1. Select the filter type.

2. Determine the External System Static Pressure (ESP)
without the filter.

3. Select a filter pressure drop from the table based upon
the number of return air openings or return air opening
size and add to the ESP from Step 2 to determine the
total system static.

If total system static matches a ESP value in the airflow table
(i.e. 0.20, 0.60, etc,) the system airflow corresponds to the
intersection of the ESP column and Model/Blower Speed row
