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 commercial applications. 5-year limited parts warranty.

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. Select the number of return air openings or calculate the return opening size in square inches to determine the proper filter pressure drop.

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

4. 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.

5. 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 .

6. 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

Example: For a 120,000 Btuh furnace with 2 return openings and 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": 2285 CFM Airflow @ 0.60": 2175 CFM

2. Subtract the airflow @ 0.50" from the airflow @ 0.60" to obtain airflow difference.

2175 - 2285 = -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.

2288 - 88 = 2197
