INSTALLATION EXAMPLES
Installation #1
With this installation, a back draft damper (optional) is insert
-
ed into the heat run before the plenum of the existing furnace
to prevent air from the existing furnace to blow back into the
furnace when it is not in use. When a back damper is em
-
ployed, it should be located as close to the existing furnace ple
-
num as practical.
INSTALLATION #3
The baffle on this system should be made the full width of the
furnace plenum in order to properly direct the air into the dis-
tribution ducts.
INSTALLATION #2
Extending the hot air duct from the furnace into the existing plenum
will help direct the flow of air from the furnace as well as the flow
in the existing furnace. Ducting entering the existing plenum at an
angle (approximately 45 degrees) will facilitate air flow from the fur
-
nace while diverting air from the existing furnace.
