Regularly check the level of water in the system and top up if required, taking care that cold water is not
added suddenly into the boiler when it is hot.
This operation must be carried out several times per season ; if not, look for the probable leak and
immediately fix it.
In the event that the heating stops during winter, increasing the risk of ice (holiday home for example), it is
recommended that sufficient anti-freeze is used to stop the heating water from freezing.
As a default, completely empty the installation (check with your installation engineer).
Titane anode
Sweep the heater.
Take out the burner drawer from the heater body.
Do not block the gas ramp openings.
With the burner out :
Take out the column head fixed by 2 screws and toothed washers
Take out the insulation
Open the sweeping trap by unscrewing the 2 screws
Clean the heater body with the special brush delivered with the
product.
To re-assemble, perform the above actions in reverse order.
Actions
It is recommended that you take out a maintenance contract with a
qualified installation engineer. In the event that this is not possible,
sign a maintenance contract with an after-sales service company
recommended by your installation engineer or De Dietrich.
Sweeping the smoke conduct and the purge tank must be carried out
at least once a year during boiler maintenance.
The magnesium anodes must be checked at least every 2, years.
After the first check, determine the frequency of future checks on the
basis of anode wear. The anodes can be checked by two methods:
- Inspection:
the anode must be replaced if its diameter is less than 15 mm
(original diameter = 33 mm)
- Function test:
- disconnect the earth wire from the anode
