▲
CAUTION
!
It is recommended that a drain pan be installed under the
furnace to prevent property damage, personal injury or
death from leaking condensate.
VERTICAL APPLICATIONS
Upflow furnace -
The connection tubing for left and right
side drainage is shipped in the blower compartment. 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.
