2.11 Putting the boiler out of operation
The boiler must be switched off and allowed to cool down before any maintenance or
repairs are carried out. If the central heating system is not going to be used for a
long time (during the holidays, forn instance, or frost-free periods) it is advisable to
put the boiler out of operation.
2.11.1 Boiler with frost protection, during longer periods of non-use
•
Set the room thermostat or other controls to a low temperature, e.g. 10°C,
•
Switch setting [P][4] to [1] (Eco mode), this will switch off the heat retention
function.
Now the boiler will only start working to protect itself against freezing. With external
frost protection, the boiler can also prevent the central heating system from freezing.
2.11.2 Boiler without frost protection, during longer periods of non-use
•
Turn time clock off and allow system to cool down then isolate mains power
supply at the fused spur unit.
•
Isolate the gas supply at the boiler valve.
Drain the boiler and central heating system if you will not be using the home
for a long period and there is a chance of night frost.

3 INSPECTION AND MAINTENANCE
The Remeha Avanta is practically maintenance free but should be inspected
annually.
If during the annual inspection the flue gas analysis indicates that the
values are outside the figures given in table 10 , maintenance work should be carried
out as described in par. 3.2 .
Also carry out maintenance if the ionisation read-out value is lower than 3 or higher
than 9µA, or when the flame core is not correct.
