CONDENSATE DRAIN INSTRUCTIONS
VERTICAL APPLICATIONS
▲
CAUTION
!
It is recommended that a drain pan be installed under the
furnace to prevent property damage or personal injury
from leaking condensate.
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.
HORIZONTAL INSTALLATION
Upflow/ Horizontal
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. This cou-
pling is only factory supplied with all 100,000 BTU up-
flow models, *UH1C080A9601A, all 120,000 BTU upflow
models, and all downflow models.

Downflow furnace - Use RTV silicon sealant to connect
the fitting to the trap for ease of removal when clean-
ing the trap.
For left side drain a 1/2" slip PVC fitting is needed.
See Figure 48.
To change to a right side drain, remove the drain lines
from the trap, rotate the trap 180° so it exits to the
right, then reconnect the lines. Start with a 1/2" 90°
CPVC street elbow connected to the trap using RTV
silicon sealant. Run 1/2" CPVC pipe to a CPVC elbow.
Run 1/2" CPVC pipe from the elbow out through the
right side knock-out. See Figure 49.
