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 (see illustration B)
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
(if fitted).
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.
5. Controller
See the user instructions supplied with the unit if you have chosen
this option.
6. Burner reset
7. Burner indicator lamp
Safety valve (heating)
If water flows from one of the safety valves, shut off the boiler and
call your heating engineer.
A monthly inspection is recommended:
Lift the lever on the emptying device for a few seconds to ensure that
the safety valve is working properly.
If a fault occurs after this short trial, call the installing
engineer.
Safety unit (domestic hot water)
A monthly inspection is recommended.
Lift the lever on the emptying device for a few seconds to ensure that
the safety unit is working properly.

serious burns.
