Condensate Neutralizers - Napoleon 9600 SERIES Installation And Operating Instructions Manual

IMPORTANT:
THE CONDENSATE DRAIN TRAP ASSEMBLY SHOULD BE FULL OF WATER 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.
A typical confi guration would be to cement the side branch of a ½" CPVC tee to the drain trap assembly
outlet, with the end branches oriented vertically. (Figure 27)
A 1" piece of ½" CPVC pipe cemented to the upper end branch will serve as a vent, which will prevent the
creation of a vapor lock, and serve as an overfl ow in the event that the drain line becomes blocked. A similarly
sized piece of pipe cemented to the lower end branch will permit connection to the condensate outlet with
⅝" id / ⅞" OD fl exible tubing, or the condensate may be piped entirely in CPVC to the fl oor drain/sump/
condensate pump.
IMPORTANT:
IF AN AIR CONDITIONING EVAPORATOR COIL DRAIN IS TO SHARE THE FURNACE DRAIN
LINE, IT SHOULD BE CONNECTED WITH A TEE FITTING DOWNSTREAM FROM THE
TRAP. DO NOT CONNECT THE EVAPORATOR COIL CONDENSATE DRAIN UPSTREAM OF
THE FURNACE DRAIN TRAP ASSEMBLY.

11.2 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.
