ownflow 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.
