- Use the personal protective equipment specified in Directive 89/391/EEC..
- Make sure the mains power is off at the master power switch.
- Ensure that the power supply cannot be restored accidentally. Remove the power plug from the socket.
- Always use proper tools.
- Once maintenance or repair activities are completed, reinstall all the protections and reactivate all the safety
devices prior to restarting the system.
6.1.1 Servicing the flue system
This is to be carried out at least once a year or after every 4 tons of fuel burned.
If the flue has any horizontal sections, remove any ash and soot before they can block the flue itself.
If it is not kept clean, the stove may experience problems including:
- poor combustion
- blackened glass
- blocked brazier, accumulated ash and pellets
- ash and excessive encrustations on the heat exchanger, which lower its efficiency.
6.1.2 Servicing the stove
This must be done at least once a year, or whenever the stove itself displays the maintenance required message.
The technician must:
- thoroughly clean the fumes circuit
- check the condition and tightness of all seals
- check the condition and cleanliness of all internal components
- check the tightness and cleanliness of the connection of the flue to the stove
- remove all pellet residue remaining in the pellet tank
- check for pellets and pellet residue in the stove's installation cavity
- check that the stove is operating properly
- reset any warnings and alarms.
