Cleaning the passage to the side of the combustion chamber

Check the passage to the left and right of the combustion
chamber for ash deposits
The amount of ash will depend on the type of fuel
used!
U
Clean the passages with a small brush and remove any
fallen ash
Checking the thermal discharge safety device
U
Check the seal of the discharge valve
´
The discharge pipe must not drip
Exception: Boiler temperature > approx. 100 °C
If water is dripping from the discharge pipe:
U
Clean the discharge safety device or have the installer
replace it if necessary
Checking the system pressure
U
Read off the system pressure on the pressure gauge
´
The value must be over the pre-stressed pressure of
the expansion tank by 20%
À
See the expansion tank’s operating instructions
If the system pressure is less:
U
Top up the water
If this occurs frequently, the heating system does not
have a good seal!
Inform your installer!
If large pressure fluctuations are observed:
U
Have the expansion tank checked
