25. Connect PS2 tubing to switch and new sensing
location.
IImmppoorrttaanntt:: Trim the condensate pressure switch
tubing to length to ensure there is no sag or
trap created.
26. Remove port cap on left of 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.
27. Install previously removed port cap onto bottom
port of the inducer.
28. Connect condensate pressure switch tubing to
pressure port on the condensate trap.
IImmppoorrttaanntt:: Trim the condensate pressure switch
tubing to length to ensure there is no
sag or trap created
29. Connect rain gutter condensate hose to the rain
gutter and the lower port of the condensate trap.
Upflow Furnace in Horizontal Left
Position - Side Vented Combustion Air
Changes do not need to be made to the inducer
orientation when installing the upflow furnace in the
horizontal left position with the combustion air vented
through the top. Changes are needed for hose routing,
condensate trap orientation, and inducer port caps.
The below figure shows the furnace as it is sent from
the factory.
Use the following steps to modify the furnace for
horizontal left with top venting of combustion air.
Before proceeding, lay unit on its back to make the
conversion easier.
1. Remove all drain hoses from condensate trap.
NNoottee:: When removing condensate hoses from the
condensate trap, hold the trap with your hand to
prevent the trap from breaking. Removing the
trap before the hoses is also an option.
2. Remove tubing from PS2 to cold header.
