Maintenance
1.
Check the siphon to ensure
unimpeded drainage of condensate.
2.
Place appropriate container
underneath siphon
.
3.
Remove sealing cap
and drain
siphon content into the container.
4.
Replace the sealing cap
w/gasket.
5.
Fill the siphon
with water by
pouring 10 fl.oz. / 0.3L of water into
the combustion chamber.
If the condensate does not drain freely,
condensate will accumulate in bottom
part of boiler resulting in a burner
shut-down (fault message F4). The
combustion chamber refractory will
also become wet at the bottom
portion. Do not restart the boiler
immediately with a wet combustion
chamber refractory. This will damage
the refractory. Either dry the refractory
or replace it.

Maintenance
1.
Check the pH value of the
condensate with a pH measuring
strip. If the pH value is less than
6.5, replace granulate.
pH measuring strip is field supplied.
2.
If contaminated:
Rinse neutralization unit with tap
water.
3.
Add granulate as marked.
The granulate is consumed as it
neutralizes the condensate. The red
marking indicates the min. filling level.
