INTRODUCTION USER GUIDE
USING THE BOILER
It is compulsory to have your system serviced every
year by a competent engineer. In the event of heavy
use of the boiler, it may require servicing on a more
regular basis than once a year. In this case, contact
your installer for advice.
Starting the burner
In conditions of normal operation, the burner starts automatically if
the temperature of the boiler is below the set point and goes off
when this value is reached.
Control panel
The user must not attempt to gain access to the
components inside the control panel.
1. On/Off switch
This turns the HeatMaster on or off.
2. Control thermostat - 60 to 90°C
When using the HeatMaster
®
as a hot water generator only, the
temperature can be set between 60°C and 90°C.
If the HeatMaster
®
is used for both hot water and central heating, the
control thermostat would normally be set at 80°C to achieve optimum
operating conditions.
3. Summer/Winter switch
This turns the heating pump
(if fitted) on or off.
4. Manual reset high limit thermostat
If the boiler temperature exceeds 103°C this safety device will
activate and the high temperature indicator will light up. To reset -
first allow the boiler to cool to below 60°C, unscrew the cap and
press the reset button using a pencil or similar pointed device,
replace the cap. If the fault persists, turn the boiler off and call an
