EFFICIENCY RATING CERTIFIED

036-21610-002 Rev. A (1104)

DESCRIPTION

These high efficiency, dedicated downflow compact units employ induced combustion, reliable hot surface ignition and high heat transfer tubular heat exchangers.

These furnaces are designed for residential installation in a closet, attic or garage and are ideal for commerci al 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 ANSI Z223.1 (latest edition).

WARRANTY

20-year limited warranty on the heat exchanger. 10-year heat exchanger warranty on commercial applica-

tions. 5-year limited parts warranty.

FILTER PERFORMANCE

The airflow capacity data published in the “Blower Performance” table listed above represents blower performance WITHOUT filters. To determine the appro ximate 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 below.

NOTE: The filter pressure drop values in the “Fi l te r Perf ormance” table shown below are typical values for the type of filter listed and should only be used as a guideline. Actual pressure drop ratings for each filter type vary between filter manufacturer.

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:

Filter Type

WASHABLE

FIBER*

Example: For a 130,000 Btuh furnace with 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.

1. Select the filter type.

2. 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 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 airflow using Step 5 or calculate the airflow by using the following example.

Airflow @ 0.50": 2110 CFM Airflow @ 0.60": 2020 CFM

2. Subtract the airflow @ 0.60" from the airflow @ 0.5" to obtain airflow difference.

2020 - 2110 = -90 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(-90) = -72

5. Subract airflow reduction value to airflow @ 0.50" to obtain actual airflow @ 0.58" ESP.

21 10 - 72 = 2038
