ALTERNATE CONDENSATE DRAIN PIPING INSTALLATION USING 1/2" PVC OR 3/4"
CPVC
1. Install the condensate trap according to instructions included in this manual. 1/2" and 5/8" rubber hoses
shown are pre-installed inside the furnace from factory.

2. If installing with 1/2" PVC, use the 1/2" hose. If installing with 3/4" CPVC, use the 5/8" hose. Slide the
appropriate hose over the condensate trap outlet and cut it fl ush with the end of the outlet. The remaining
rubber should be fl ush with the end of the outlet on the condensate trap. The remaining hose is suffi cient
length to accommodate all furnace orientations.

3. A 1/2" PVC coupling or bushing will fi t snug over the 1/2" rubber hose. A 3/4" CPVC coupling or bushing will
fi t snug over the 5/8" rubber hose. This method ensures a water tight seal and also allows the condensate
trap to be easily removed for service.

4. If extra security is desired, it is recommended to secure a strip of strapping around the drain. Utilize the
existing condensate trap screws to secure the strapping.

CONDENSATE NEUTRALIZERS
Some local codes may require the use of a condensate neutralizer. If the furnace condensate is to be routed to
a septic system, it may be advisable to use a condensate neutralizer.
When condensate neutralizers are used, it is advisable to install it with an overfl ow bypass tube.
