INSTALLATION INSTRUCTIONS
DESCRIPTION
This external filter rack kit is intended to provide a location,
external to the furnace casing, for installation of a permanent
filter. The rack is designed to mount over the indoor air blower
compartment area of either side panel, and provide filter retention as well as a location for attaching return air ductwork.
ATTENTION INSTALLING PERSONNEL
As a professional installer, you have an obligation to know the
product better than the customer. This includes all safety precautions and related items.
Prior to actual installation, thoroughly familiarize yourself with
this Instruction Manual. Pay special attention to all safety warnings. Often during installation or repair, it is possible to place
yourself in a position which is more hazardous than when the
unit is in operation.
Remember, it is your responsibility to install the product safely
and to know it well enough to be able to instruct a customer in
its safe use.
Safety is a matter of common sense... a matter of thinking
before acting. Most dealers have a list of specific, good safety
practices... follow them.
The precautions listed in this Installation Manual are intended
as supplemental to existing practices. However, if there is a
direct conflict between existing practices and the content of
this manual, the precautions listed here take precedence.

IMPORTANT INFORMA TION
Contact a local propane gas supplier
about installing a gas detecting warning device.
NOTE: To ensure proper operation, install, operate and maintain the unit in accordance with these installation instructions,
all local building codes and ordinances. In their absence,
follow the latest edition of the National Fuel Gas Code (NFPA

LOCA TION & PLACEMENT
This kit is designed for side panel application to Upflow 34.5”
90% gas furnace models. Refer to Installation Precautions
and Considerations section for details.
NUMBER OF KITS REQUIRED
Less Than Five Tons of Airflow
Installations supporting less than five tons of airflow require
only one return air ductwork connection when a permanent
filter is used. For this case one filter rack kit is required.
NOTE: This filter rack cannot be applied to a bottom return on
90% furnaces.
Five Tons of Airflow
Installations supporting five tons of airflow require two return air
ductwork connections. If both connections are side panel connections, two filter rack kits are required. When a bottom
return is used in conjunction with a side panel connection, a
permanent filter must be installed in the bottom return and a
filter rack kit used for the side panel connection.
NOTE: This filter rack cannot be applied to a bottom return
on 90% furnaces.
