9. The horizontal installation of the upflow
furnace requires an external filter section. Do
NOT use the bottom return filter within the
furnace. Filter kits are available for horizon-
tal applications.
10. Connect duct work to furnace. See Outline Drawing
for supply and return duct size and location. Flex-
ible duct connectors are recommended to connect
both supply and return air ducts to the furnace. If
only the front of the furnace is accessible, it is
recommended that both supply and return air
plenums are removable.
