MAINTENANCE

Disconnect the electric supply to the burner by switching off the main power switch and close the
gas shut-off valve before maintaining or checking the system.
The burner requires scheduled maintenance that must be carried out by qualified personnel and in compli-
ance with local legislation.
Scheduled maintenance is vital for the smooth operation of the burner; it avoids waste of fuel and reduces
harmful emissions into the atmosphere.
