28. Connect PS2 tubing to switch and new sensing
location.
IImmppoorrttaanntt:: Trim the PS2 pressure switch tubing to
length to ensure there is no sag or trap
created.
29. Remove port cap on the right side of the inducer
and connect inducer condensate tubing. Connect
other end of inducer condensate tubing to top port
on the condensate trap. Cut tubing to length, if
necessary.
30. Install previously removed port cap onto bottom
port of the inducer.
31. Connect condensate pressure switch tubing to
pressure port on the condensate trap.
IImmppoorrttaanntt:: Cut to length to ensure there is no sag
or trap created.
32. Connect rain gutter condensate hose to the rain
gutter and the lower port of the condensate trap.
Furnace in Horizontal Right
Position - Left Vented
Combustion Air
Changes need to be made to the inducer orientation
when installing the upflow furnace in the horizontal
right position with the combustion air vented through
the bottom. Additional changes are needed for hose
routing, condensate trap location, and inducer port
caps, and the condensate plug.
The figure below shows the furnace as it is sent from
the factory.
Use the following steps to modify the furnace for
horizontal right with bottom venting of combustion air.
IImmppoorrttaanntt:: PS2 conversion does not apply to the S9X1
or S9B1 models.
Before proceeding, lay unit on its back to make the
conversion easier.
1. Remove all drain hoses from condensate trap.
