FILTER PERFORMANCE
The airflow capacity data published in the “Blower Perfor-
mance” table listed above represents blower performance
WITHOUT filters.
All applications of these furnaces require the use of field
installed air filters. All filter media and mounting hardware or
provisions must be field installed external to the furnace cabi-
net. DO NOT attempt to install any filters inside the furnace.
NOTE:
Single side return above 1800 CFM is approved as
long as the filter velocity does not exceed filter manufac-
turer’s recommendation and a transition is used to allow use
on a 20x25 filter.
NOTES:
1. Air velocity through throwaway type filters may not exceed 300
feet per minute (91.4 m/min). All velocities over this require the
use of high velocity filters.
2. Do not exceed 1800 CFM using a single side return and a 16x25
filter. For CFM greater than 1800, you may use two side returns or
one side and the bottom or one return with a transition to allow
use of a 20x25 filter.
* - 24" clearance in front and 18" on side recommended for service access.
All furnaces approved for alcove and attic installation.
