Condensate Drains
Condensate is produced in furnace sections during heating operation. Installation
requires an
individual condensate drain system
for each duct furnace section. A fully
condensing furnace operating at 100,000 Btuh can generate up to 1 gallon of
condensate per hour.
An overflow switch is provided on the collector box to shut-off the furnace in the event
that condensate accumulates in the flue collector box.
Condensate trap kits are provided with each duct furnace.
The condensate drain system must include a trap for each furnace for proper system
performance. All joints must be watertight to prevent leakage. The heat exchanger
assembly includes a threaded elbow in the flue collector box, oriented parallel to cabinet
base.
A male threaded PVC adapter is included in the EZ Trap kit provided with the furnace to
connect to the threaded elbow on the flue collector box. Glue necessary PVC pipe and
fittings to connect condensate piping to a suitable drain. Be sure to apply sealant to
threads to prevent leakage. Installation of a union ahead of the trap is preferred to permit
maintenance of drains and accommodate service of the heater.
