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 orig-
inal purchaser; a 20-year limited warranty from original instal-
lation date to subsequent purchaser.
10-year warranty on the heat exchanger in commercial appli-
cations.
5-year limited parts warranty.

FILTER PERFORMANCE
The airflow capacity data published in the “Blower Perfor-
mance” table listed above represents blower performance
WITHOUT filters. To determine the approximate blower per-
formance of the system, apply the filter drop value for the fil-
ter being used or select an appropriate value from the “Filter
Performance” table shown.
NOTE: The filter pressure drop values in the “Filter Perfor-
mance” table shown are typical values for the type of filter
listed and should only be used as a guideline. Actual pres-
sure drop ratings for each filter type vary between filter manu-
facturer.
NOTES:
1. Air velocity through throwaway type filters may not exceed 300
feet per minute. All velocities over this require the use of high
velocity filters.

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 3 to determine the
total system static.
4. If total system static matches a ESP value in the airflow
table (i.e. 0.20, 0.60, etc,) the system airflow corre-
sponds to the intersection of the ESP column and Model/
Blower Speed row.
5. If the total system static falls between ESP values in the
table (i.e. 0.58, 0.75, etc.), the static pressure may be
rounded to the nearest value in the table determining the
airflow using Step 5 or calculate the airflow by using the
following example.
Example: For a 120,000 Btuh furnace operating on high
speed blower, it is found that total system static is 0.58" w.c.
To determine the system airflow, complete the following
steps:
1. Obtain the airflow values at 0.50" & 0.60" ESP.
Airflow @ 0.50": 2152 CFM
Airflow @ 0.60": 2042 CFM
2. Subtract the airflow @ 0.50" from the airflow @ 0.60" to
obtain airflow difference.
2042 - 2152 = -110 CFM
3. Subtract the total system static from 0.50" and divide this
difference by the difference in ESP values in the table,
0.60" - 0.50", to obtain a percentage.
(0.58 - 0.50) / (0.60 - 0.50) = 0.8
4. Multiply percentage by airflow difference to obtain airflow
reduction.
(0.8) x (-110) = -88
5. Subract airflow reduction value to airflow @ 0.50" to
obtain actual airflow @ 0.58" ESP.
2152 - 88 = 2064
