VIII. Condensate Disposal
A. Condensate trap
1. The condensate trap is located inside the appliance
jacket behind the front door panel.
a. The flue gas trap prevents flue gases from
escaping into the boiler room.
b. The float switch interrupts the limit string in the
event the drainage of the condensate is blocked.
2. The condensate line exits out the back of the
appliance through a 1" PVC pipe.
3. Note the following when disposing of the
condensate:
a. Condensate is slightly acidic, typical pH around
3.5 - 4.5. Do not route the drain line through areas
that could be damaged by leaking condensate.
b. Use continuous Teflon, high temperature silicone
tubing, or other tubing material compatible with
flue gas condensate for condensate piping.
c. Do not route or terminate the condensate drain
line in areas subject to freezing temperatures.

NOTICE
NOTICE
Do not crimp condensate drain lines or reduce
drain line inner diameter size.
Do not manifold condensate drains and vent drains
together.
Consult local authorities regarding disposal of flue
gas condensate into the public waste water system.
Do not use metallic pipe or fittings for condensate
drain lines.
d. If the point of condensate disposal is above
the trap, a condensate pump is required to
move the condensate to the drain. Select
a condensate pump approved for use with
condensing appliance—and equipped with an
overflow switch.
e. Do not attempt to substitute another trap for one
provided with the appliance.
f. Slope condensate drain pipe at least 1/8” per foot
in the direction of discharge.
