4.2 Inspection and cleaning
 Regular cleaning of the boiler extends its life and is a basic
requirement for smooth running based on output. So clean the
boiler regularly!
 Recommended: When cleaning, use an ash vacuum.
4.2.1 Inspection
Checking the thermal discharge safety device
 Check the seal of the discharge valve at regular intervals
 The discharge pipe must not drip
 Exception: boiler temperature > 95 °C
If water is dripping from the discharge pipe:
 Clean the discharge safety device or have the installer replace it if
necessary
Check safety valve
 Check the safety valve as per the manufacturer’s instructions.
 See the operating instructions of the safety valve
Check the system pressure
 Read off the system pressure on the pressure gauge
 The value must be above the pre-stressed pressure of the
expansion tank by 20%
 Expansion tank operating instructions
If the system pressure decreases:
 Top up the water
 If this occurs frequently, the seal of the heating system is faulty!
Inform your installer!
In case of large pressure fluctuations:
 Have the expansion tank checked
Check the geared motors
 Carry out a visual inspection of the seal on the geared motors of the
stoker screw and ash screw
 There must not be a large quantity of lubricant coming out.
 If a few drops of lubricant are coming out, this can be normal. If a lot
of lubricant is being lost, inform your installer or Fröling customer
services.
