MAINTENANCE

Regular maintenance is essential for the
safety, efficiency and durability of the boiler.
Proper maintenance keeps consumption and
emissions down, and ensures that the prod-
uct continues to operate reliably over time.
Have your boiler serviced either by a
Technical Assistance Centre or by a qualified
heating engineer. Analyse the combustion
fumes before commencing maintenance.
The results of fume analysis can give a clear
idea of what servicing or repairs are needed.
Perform the following operations before
beginning any maintenance.
- Switch the electricity supply OFF at the sys-
tem's main switch and at the control panel.
