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

Therefore, the central heating pipelines and the

radiators must reach this temperature.

HOT

The waste-gas pipe lines must reach

temperatures in excess of 100°C.

The hot water can reach temperatures in excess

of 60°C.

Installation

Before installing and commissioning the boiler, first carefully read this manual.

Faults

Despite the strict quality standards imposed on its appliances by ACV during production, inspection, and transport, faults may occur. Please immediately inform your approved installer about such faults. Remember to give the fault code as it appears on the screen.

Only genuine factory parts may be used as replacement parts. Please go to page 13 for a list of spare parts and their ACV reference numbers.

Important note: ACV reserves the right to change the technical characteristics and specification of its products without notice.

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 engineer.
