10.10 Checking the condensate drain
pipe
The condensate drain pipe 35 (Fig. 10.19)
does not require any particular maintenance
but just check:
• That no solid deposits have formed, if so re-
move them.
• That the condensate drain piping is not
clogged.
To clean the inside of the siphon, remove it
and turn it upside down to remove any dirt.

Check appliance for gas tightness.
Re-check operational pressures as described
in section "Checking the gas supply pressure"
on page 55 of this manual.

10.13 Water inhibitor concentration

Where chemical products are used the level
of water treatment should be checked on an
annual basis and re treated after full or partial
drain down.
A conductivity meter can be used to check the
correct concentration of inhibitor in the heat-
ing water.

With the boiler set in flue sweep mode, it is
possible to exclude some boiler automatic
functions making check and control opera-
tions easier.
