FILTER PERFORMANCE
The airflow capacity data published in the “Blower Perfor- mance” table 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 manufacturer’s rec- ommendation and a transition is used to allow use of a 20 x 25 filter.

NOTES:
1.Air velocity through throwaway type filters may not exceed 300 feet per min- ute (91.4 m/min). All velocities over this require the use of high velocity fil- ters.
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.

Combustible Floor Base Kit -
For installation of these furnaces in downflow applications directly onto combustible flooring material, These kits are required to prevent potential overheating situations. These kits are also required in any applications where the furnace in installed in a downflow configuration without an evaporator coil, where the combustible floor base kit provides access for com- bustible airflow.
