The values in the tables are measured at the
nominal useful power with factory calibration.
9.12 Checking the condensate drain
pipe
The condensate drain pipe 39 (Fig. 9.20) 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.
Unscrew the plug to clean inside the pipe.

9.15 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 conductivitymeter can be used to check the
correct concentration of inhibitor in the heat-
ing water.
9.16 Setting the boiler chimney
With the boiler set in chimney sweep mode, it
is possible to exclude some boiler automatic
functions making check and control opera-
tions easier.
• Enter in "programming mode" by pressing
keys 14 - 17 - 18 (Fig. 9.21) for 10 seconds
at the same time until the letters P01 are
displayed on the LCD display, indicating that
