5.3 Maintenance work by the operator

❒ Regular cleaning of the boiler extends its life and is a basic requirement for

smooth running.

❒ Recommendation: use an ash vacuum for cleaning.

 

5.3.1 Weekly inspection

Checking the system pressure

❒ Check the system pressure on the pressure gauge

➥ The value must be 20% above the pre-stressed pressure of the expansion tank

NOTICE! Check that the position of the pressure gauge and rated pressure of
the expansion tank match your installer's specifications!

 
If the system pressure decreases:

❒ Top up with water

NOTICE! If this happens frequently, the seal of the heating system is faulty! Inform

your installer

 
If large pressure fluctuations are observed:

❒ Ask an expert to inspect the expansion tank

 

Check the thermal discharge valve (from T4e 130)

❒ Check the seal of the discharge valve

➥ The discharge pipe must not drip

NOTICE! Exception: Boiler temperature > 100 °C

If water is dripping from the discharge pipe:

❒ Clean the discharge safety device in accordance with the manufacturer's

instructions or have it checked/replaced by the installer if necessary

 

Checking the safety valve

 

❒ Check the seal of the safety valve regularly and ensure that the valve is not dirty

NOTICE! Inspection work must be carried out in accordance with the

manufacturer’s instructions.
