USER GUIDE

USING THE BOILER

Your system should be serviced at least once a year by a qualified engineer.

If the boiler is subject to heavy use, it may require servicing more than once a year - consult your service engineer for advice.

Starting the burner:

In normal operation, the burner starts automatically whenever the boiler temperature falls below the set temperature.

Understanding the control panel

There are no user parts inside the control panel.

Control panel HeatMaster 70 N and HeatMaster 100 N

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 engineer.

set the time clock simply push outwards the number of tabs required for ON period.

Remember:

TAB IN = HeatMaster OFF

 

TAB OUT = HeatMaster ON

6. Temperature and pressure gauge

This gauge indicates both the temperature of the HeatMaster and the pressure within the primary circuit.

The temperature should not exceed 90 °C - if it does, switch the boiler off and check the thermostat setting. If the fault persists, call an engineer.

The pressure should not fall below 1bar, if it does the please see the 'Heating System Pressure' paragraph later in this section.

7. Low primary water pressure indicator

If this indicator lights up, the primary circuit of the HeatMaster requires topping up with water. Please see the 'Heating System Pressure' paragraph later in this section.
