CONDENSATE DRAIN INSTRUCTIONS

CAUTION
!
IT IS RECOMMENDED THAT A DRAIN PAN BE INSTALLED
UNDER THE FURNACE TO PREVENT PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH FROM LEAKING CONDEN-
SATE.
VERTICAL APPLICATIONS
Upflow furnace - The connection tubing for left and
right side drainage is shipped in the blower compart-
ment. Install the connection tubing from the trap to the
side of the unit and trim all excess tubing to avoid
kinks.
Downflow furnace - The furnace is shipped with the
left side drainage setup. To change the right side drain,
remove the drain lines from the trap, rotate the trap
180° so it exits to the right, reconnect the lines, and run
a 1/2" CPVC pipe from the trap out through the right
side knock-out. Use RTV silicone sealant to connect the
CPVC pipe to the trap for ease of removing to clean the
trap.
