USING THE BOILER
Have your system serviced every year by a qualified
heating engineer. If the boiler is subject to heavy
usage, it may need more frequent servicing. If this is
the case, ask your installer for advice.
Starting the burner:
In normal operation, the burner starts automatically
whenever the boiler temperature falls below the set
temperature.
Before doing any work on the boiler, switch off the
power at the mains switch installed in the boiler room
by the electrician.
On the control panel, switch off the ON/OFF switch.
Getting to know the control panel
The user should not access the components inside
the control panel.
1. Control thermostat - 60 to 90 °C
When the boiler is used only to produce domestic hot water, the
temperature can be set between 60 and 90 °C. If the boiler is used
for both hot water and heating, the control thermostat will, as a
general rule, be set to 80 °C to ensure optimum operating conditions.
2. ON/OFF switch
Used to start and stop the boiler.
3. Summer/winter selector
Starts and stops the heating pump
4. Thermometer
Shows the boiler temperature in the primary circuit.
The temperature should not exceed 90 °C. If it does, switch off the
boiler and check the thermostat settings. If there is a fault, call a
heating engineer.
