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 programme
( , 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
and Use ) using correctly calibrated instruments with current
test certification.
To commission the boiler the casing has to be removed. The casing is locked with a
screw behind the door on the front and the top of the casing is hooked behind a locking
edge. After removing this screw the casing must be lifted at the bottom by which means
it is released from the locking edge. Then 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 once-only, which
means that adjusting of these values is unnecessary. Only in case of replacing of the
gas valve, venturi and/or fan the zero pressure and the CO2 adjustment has to be
checked and, if necessary, adjusted at the right 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 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;
- Press the STEP-key until 2 is shown;
alternately 2 and OFF will be shown.
