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.
When the factory supplied “off-set” (2X3 reducing cou-
pling) 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 conden-
sate drainage. This coupling is factory supplied only with
the following models: UC120 & DC120, UX120 & UY120,
UX100 & UY100, UX808C960, and All DX & DY models.

end towards the furnace.
All horizontal stainless steel sections must be posi-
tioned with the seam on top.
All long horizontal sections must be supported to pre-
vent sagging.
All pipe joints must be fastened and sealed to prevent
escape of combustion products into the building.

Both venting methods shown in Figure 40 & 42 must
also have the combustion air inlet installed - meeting
dimension requirements of Figure 36.
