12 Isolating the boiler
In some situations it may be that the entire boiler must be switched off. By switching
off the three keys with the lamps for central heating, hot water and pump program (
,
or ), the boiler is switched off. Leave the plug in the wall socket, which means
the circulation pump and the three-way valve are activated once every 24 hours in order
to prevent jamming.
In the event of frost danger it is advisable to drain the boiler and/or the
installation.
13 Commissioning
Work on the boiler must be carried out by a competent person, (Ref: Gas
Safety, Installation & Use Regulations )
using correctly calibrated instruments
with current test certification.
To commission the boiler the casing has to be removed.
Remove the lower part of the casing which covers the expansion vessel (if present)
forward. The casing is fixed by 4 quick release clamps and 5 screws (4x 1 clamp and 1
behind door). After removing the screws, unlock the clamps, now the casing can be
removed forward.
The boiler settings, such as burner pressure and adjustment of the air quantity are
unnecessary, due to the fact that the boiler operates with a so-called zero pressure
control. This means the correct gas quantity is controlled by the suction operation of the
fan. The fine adjustment which is carried out at the factory is one off, which means that
adjusting of these values is unnecessary. Only when replacing the gas valve, venturi and/
or the fan, does the zero pressure and the incorrect CO2 adjustment have to be checked
and, if necessary, adjusted to the correct value.
Always check the installation of all parts through which gas flows (using
leak-search spray)
13.1 Checking for contamination
In order to be able to check the boiler for contamination in the following running years
it is advisable to measure the maximum air displacement in the boiler when putting the
boiler into operation. This value can be different with each type of boiler.
In order to be able to measure this value follow the next procedure:
- Press the Central Heating and DHW buttons once to ensure that the boiler is OFF
and not firing.
- Press the MODE-key for 5 seconds.
- The diplay will show COdE followed by an arbitrary number;
- Select by means of the + or the - key the code C123;
- Press the Store-key to confirm the code (code blinks 1 x);
- Press the MODE-key until SERV is shown;
