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. Approved power venters are Fields Controls Model SWG-4Y or Tjernlund Model GPAK-JT. Follow all application and installation details provided by the manufacturer of the power vent. This unit may be horizontally vented using 4” (10.2 cm) diameter pipe with a minimum length of 4.5 feet (1.37 m) and a maximum length of 34.5 feet (10.82 m) with up to 4 elbows.

FILTER PERFORMANCE

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 below.

NOTE: The filter pressure drop values i n the “Filter Performance” 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.

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.

2. Air flows above 1800 CFM require either return from two sides or one side plus bottom.

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 w.c. (50 Pa), 0.60 w.c. (150 Pa), 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 w.c. (144 Pa), 0.75 w.c. (187 Pa), 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 60,000 BTUH (17.58 kW) furnace with a bottom return opening 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:

Obtain the airflow values at 0.50 w.c. (125 Pa) & 0.60 w.c. (150 Pa) ESP.

Airflow @ 0.50”: 1250 CFM (35.4 m Airflow @ 0.60”: 1180 CFM (33.4 m Subtract the airflow @ 0.50 w.c. (125 Pa) from the airflow @

0.60 w.c. (150 Pa) to obtain airflow difference.

1180 - 1250 = -70 CFM (-12 m3/min) Subtract the total system static from 0.50 w.c. (125 Pa) and

divide this difference by the difference in ESP values in the table, 0.60 w.c. (150 Pa) - 0.50 w.c. (125 Pa), to obtain a percentage.

(0.58 - 0.50) / (0.60 - 0.50) = 0.8 Multiply percentage by airflow difference to obtain airflow

reduction. (0.8) X (-70) = -56 Subtract airflow reduction value to airflow @ 0.50 w.c. (125

Pa) to obtain actual airflow @ 0.58 in. w.c. (144 Pa) ESP. 1250 - 56 = 1194
