1.2 General Information
A Model RBL blower cabinet is engineered for use with Reznor ® duct furnaces when
design considerations do not permit the use of a packaged system. The cabinet is
weatherized with an integral curb cap base for outdoor installation, but may also be
installed indoors. The blower cabinet has standard horizontal inlet and outlet air open-
ings equipped with duct flanges and may have an optional bottom air inlet. Model RBL
is available with a downturn plenum which provides a bottom outlet for supply air.
This booklet includes installation and operation information. Installation should be
done by a qualified agency in accordance with the instructions in this manual and in
compliance with all codes and requirements of authorities having jurisdiction. Before
beginning installation, review the instructions in this booklet and become familiar with
the required procedures.
