Installing the System Piping
Before connecting the condensate drain, choose
one of the following disposal options:
a
b
c
d
a. From the boiler directly into an external
drain.
Note
Do not install a fixed connection for
the drain.
b. From the boiler, through a neutralizing
agent, and then into an external drain (refer
to “3.3.1 Condensate Neutralizer Kit” on
Note
If you choose this option, the
neutralizing agent must be replaced
periodically. Depletion of the
neutralizing agent will vary, based
on the usage rate of the boiler.
During the first year of operation,
the neutralizer should be checked
every few months for depletion and
replaced as needed.
c. From the boiler into a laundry tub.
Note
The bottom of the boiler must
be higher than the top of the
laundry tub to use this option.
The condensate line must have a
negative slope to drain properly.
d. From the boiler into a condensate pump,
and then into a laundry tub.
Note
A pump can be used when there is
a long distance between the boiler
and the laundry tub or when the
bottom of the boiler is lower than
the top of the laundry tub.
2. Insert the condensate trap to the drain adapter
at the bottom of the boiler.
3. Attach the clip to the condensate trap.
4. Ensure that the condensate trap is firmly fixed to
the bottom of the boiler.
