4.1 Cleaning the Ceramics
Remove the ceramics as detailed in A - E above.
Gently clean the ceramics in the open air, using a soft brush and a vacuum cleaner. Where necessary replace
damaged components only with genuine Heat Design specified parts. Seal any scrap ceramics in plastic bags and
dispose at proper refuse sites. When using a vacuum cleaner, it is recommended that one with a HEPA filtering
system is used.
Re-fit the Firebed arrangement, re-seal the appliance and check the safe operation of the appliance.
4.2 Servicing the Burners
Remove the Burner Top Assemblies as detailed in A - H above.
The pilot is now clearly visible, the pilot, including the Thermocouple, can be replaced/serviced by removing
raising the pilot assembly from its mounting. This is done by removing the two screws on the surface of the
pilot. The fittings on the under-side of the pilot can be un-done using a 10mm spanner where appropriate.
To access the Main Burner Injectors, the Burner base units must be removed. This is done by removing the six
bolts (M6, 10mm spanner) holding the burner in. With these six bolts removed, the Burner base can be raised up
through the Firebox, and the Injectors can be easily accessed.
When replacing any parts use only original Heat Design specified parts.
