Control: that the ionisation current is at a value over 4
(follow the procedure in chapter 8.13)
Control: that the exhaust flue system is not being
affected by high gusts of wind or nearby mechanically
operated fans
If the ionisation current is not over 4, the CO2 must be
checked (follow chapter 6.8) and restore the correct
value. Check the ionisation electrode and replace it if
necessary. Check the integrity of the ionisation current
electric circuit cables.
If a horizontal exhaust flue terminal is exposed to
unusually high wind conditions or nearby mechanically
operated fans then a suitable deflection shield or
protection should be considered or an alternative
location should be considered. The same approch
should be taken for a vertical exhaust flue and in
addiction, ceck that downdraughts are not being
encountered due to the proximity of higher roof profiles.

The D.H.W. outlet
sensors measure the dif-

more than 60 seconds.
Check that the electrical resistance of the two sensors
match the graphics in chapter 8.15;
If one of the two or both sensors do not have correct
values, they must be replaced;
