IMPORTANT:
THE CONDENSATE DRAIN TRAP ASSEMBLY SHOULD BE FULL OF WATER (PRIMED)
BEFORE STARTING THE FURNACE. TO FILL THE CONDENSATE DRAIN TRAP ASSEMBLY,
TEMPORARILY REMOVE THE VENT DRAIN HOSE FROM THE EXHAUSTER ASSEMBLY
ELBOW/DRAIN FITTING, AND POUR APPROXIMATELY ONE CUP OF WATER DOWN THE
HOSE. WATER WILL BEGIN RUNNING OUT THE CONDENSATE DRAIN TRAP OUTLET
WHEN IT IS FULL. REFASTEN THE VENT DRAIN HOSE TO THE EXHAUSTER ASSEMBLY
ELBOW/DRAIN FITTING.
THE CONDENSATE DRAINAGE CONFIGURATION REQUIRES A VENT. IT TAKES LESS
THAN A ONE INCH RISE ANYWHERE ALONG THE HORIZONTAL ROUTE OF THE DRAIN
TUBE TO CREATE A VAPOR LOCK, WHICH WILL PREVENT CONDENSATE FROM
DRAINING AWAY FREELY, AND RESULT IN ERRATIC FURNACE OPERATION.
1. The supplied parts bag includes a length of 1/2” and 5/8” rubber hose and the condensate trap. Install the
condensate trap according to instructions included in this manual.

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 suf
fi
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.
