1. When the furnace is installed in the horizontal right or left
application and a return duct is attached to the top side, do not
install a filter in the return duct directly above the furnace. Install
the filter in a remote location.
When the furnace is installed in the horizontal right or left
application and a close coupled (less than 36") return duct is
attached to the bottom side of the furnace as shown above,
securely attach a 1/2" mesh metal hardware cloth protective
screen to the inside bottom of the filter grille
to prevent
personal injury from contacting moving parts when
reaching into the return opening to replace the filter.
Close coupled (less than 36") return (filter directly beneath
bottom side return) is not recommended due to noise
considerations.
2. Connect the duct work to the furnace. See Outline Drawing for
supply and return duct size and location.
Flexible 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.
3. When replacing a furnace, old duct work should be cleaned out.
Thin cloths should be placed over the registers and the furnace
fan should be run for 10 minutes. Don’t forget to remove the
cloths before you start the furnace.
4. The horizontal installation of the upflow furnace requires
an external filter section. Filter kits are available for
horizontal applications.

RETURN AIR FILTERS FOR FURNACE IN HORIZONTAL
