Condensate Trap Installation
1. Reinstall the condensate adapter if it was earlier removed or
ensure adapter is still in place.
Important: The condensate adapter must be present for proper
condensate drain operation.
2. Install condensate trap into new location by fitting into grommet
and aligning the hole on the condensate trap with the hole labeled
"HL".
When installing a 21.0" wide S-Series furnace, the condenser trap
grommet must be rotated so that the notch in the grommet faces the
outer edge of the furnace cabinet as shown in the illustrations. This
allows the rain gutter tubing to fully seat onto the lower condensate
port trap.
3. Hand tighten screws.
1. Connect PS2 tubing to switch and new sensing location.
Important: Cut to length but insure there is a rise in the tubing to
avoid condensed flue gases from entering pressure
switch.
2. Remove port cap on left side 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.
3. Install previously removed port cap onto bottom port of the
inducer. (As viewed in upflow)
4. Connect condensate pressure switch tubing to pressure port on
the condensate trap.
Important: Trim the condensate pressure switch tubing to
length to ensure there is no sag or trap created.
5. Remove port plug from rain gutter and install in new position on
opposite side of the rain gutter.
6. Connect rain gutter condensate hose to the rain gutter and the
lower port of the condensate trap. Route rain gutter condensate
hose to the right of the inducer motor.
