Drain Hose Installation; Drain Piping - Napoleon 9600 B SERIES Installation And Operating Instructions Manual

THE TWO INLETS TO THE DRAIN TRAP ARE FOR VENT PIPE AND CONDENSATE
COLLECTION. THE VENT PIPE INLET IS SMALLER THAN THE CONDENSATE
COLLECTION INLET. ENSURE THAT THE DRAIN HOSES ARE PROPERLY CUT TO THE

11.4 DRAIN HOSE INSTALLATION

1. Connect one end of the 5/8" tubing (in parts bag) to the most direct drain outlet on the front manifold cover,
and the other end to the larger elbow on the condensate trap assembly. Cut excess tubing if necessary
and hold in place with the supplied plastic hose clamps (in parts bag).
2. Connect one end of the 1/2" tubing, using the reducing coupling (in parts bag), to the lower drain outlet
on the exhauster coupling, and the other end to the smaller elbow on the condensate trap assembly. Cut
excess tubing if necessary.
NOTE
All condensate drain tubing must slope towards the condensate trap, ensuring that the drain
hoses do not create traps or kinks in the hose prior to the condensate trap assembly.
11.4.1

DRAIN PIPING

Condensate from the outlet of the drain trap assembly must be conveyed to a fl oor drain, sump pit, or, if these
are unavailable, to a condensate pump. If using a condensate pump, be sure that it is approved for furnace
condensate.
DO NOT DRAIN THE CONDENSATE OUTDOORS. DO NOT RUN THE CONDENSATE LINE
THROUGH AREAS WHERE FREEZING MIGHT OCCUR. FREEZING OF CONDENSATE CAN
RESULT IN ERRATIC FURNACE OPERATION AND IN PROPERTY DAMAGE.
A typical confi guration would be to cement the side branch of a 1/2" CPVC tee to the drain trap assembly
outlet, with the end branches oriented vertically. (Figure 15)
A 1" (25mm) piece of 1/2" 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 5/8" ID / 7/8" OD fl exible tubing, or the condensate may be piped entirely in CPVC to
the fl oor drain/sump/condensate pump.
NOTE
It is recommended that the condensate drain assembly not be cemented to the condensate trap
outlet, if removal of the condensate trap is required in the future. Use a piece of the provided 1/2"
drain hose if removal of the condensate trap is anticipated.
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.
