NOTE:

In horizontal venting when the factory supplied “off- set” (2X3 reducing coupling) is used for 3” vent pipe installation, make sure the marking “Top” is located on the top side of the pipe. The straight side must be on bottom for proper condensate drainage.

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.
