Condensate Disposal
WARNING
Asphyxiation Hazard.
Failure to install condensate drain in
accordance with instructions outlined below
could cause products of combustion and/or
carbon monoxide to enter building, resulting
in severe personal injury, death or substantial
property damage.
!
1. This high efficiency boiler produces condensate.
NOTICE:
Condensate is corrosive. Use only
materials listed by authority having jurisdiction. In
absence of such requirements, PVC and CPVC
pipe may be used.
2. 3/4 in. PVC condensate drain connection can be
solvent welded.
3. Condensate disposal considerations:
A. If required by local codes, install neutralizing
filter. Neutralizing kit P/N 101897-01 is
available from manufacturer.
3/4" PVC Connection
Condensate Trap Vent
Condensate Trap Cleanout
B. Do not route or terminate condensate drain
line piping through an area that is prone
to freezing temperatures or that could
be damaged by leaking condensate.
C. If point of condensate disposal is above trap,
it will be necessary to use a condensate
pump to move condensate from boiler to
drain.
In such cases, select a condensate pump that
is listed for use with condensing boilers.
Select a pump with an overflow switch to
prevent property damage from condensate.
D. Barbed fitting on bottom panel is connected
to trap vent and must be unobstructed for trap
to work properly.
NOTICE:
If condensate drain line becomes
obstructed, boiler may leak from condensate
trap vent. Consider installing drain pan directly
below boiler if such a leak could cause property
damage. Pipe drain pan drain to suitable location.
