• The ignition/detection electrode "P" in Fig.
10.12 also functions as a sensor for the
correct drainage of the condensate.
Should the mentioned electrode come
into contact with the condensate water
present within the combustion chamber
it sends the boiler into safety lockout.
Therefore, should the insulation be wet or
deteriorated, provide for the substitution
of the same.
