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 the appropriate Tjernlund GPAK
model. 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 mini-
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

mum 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.
FILTER PERFORMANCE - PRESSURE DROP INCHES W.C. AND (KPA)
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 e ither 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.
3
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
