Cleaning the passage to the side of the combustion chamber
U Open the insulating door and combustion chamber door
U 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
