• In case of anomaly, please call your service engineer. • In spite of the strict quality standards that ACV applies to its appliances during production, inspection and transport, faults may occur. Please immediately notify your approved installer of any faults.
USE OF THE BOILER ACV recommends that the boiler is inspected and serviced, if required, at least once a year by a competent and qualified engineer. More frequent servicing may be required depending on boiler use, if this is the case consult your installer for advice.

The temperature of the domestic hot water can be adjusted up to 90 °C in the boiler. However, the temperature of the domestic hot water at the drawing point must comply with local regulations. (E.g. in Belgium, the maximum DHW water temperature at a drawing point must be 75°C for boilers < 70 kW). For special applications, please contact ACV. EN • 12 664Y6100 •...

The hot water output may reach temperatures in excess of 60°C, which can cause burns. ACV therefore recommends that you install a thermostatic mixing valve immediately after the appliance outlet. EXAMPLE OF SERIES CONNECTION...
INSTALLATION HEATING CONNECTION The DHW tank must be pressurized before putting the primary circuit (heating) under pressure. Two couplings are installed at the back of the HeatMaster®, that can be used to connect a central heating circuit. Connecting a heating system may reduce the domestic hot water performance.
STARTING UP FILLING THE DOMESTIC HOT WATER AND STARTING UP THE BOILER HEATING CIRCUITS STARTING THE BURNER 1. Set the boiler master switch on ”ON” and the summer/winter switch on the ” ”. symbol. 2. Rotate the boiler control thermostat clockwise to generate a heat IMPORTANT demand.
MAINTENANCE ANNUAL MAINTENANCE ACV recommends the boilers should be serviced at least once a year. Maintenance and the burner control must be performed by a qualified engineer. More frequent servicing may be required depending on boiler use. If this is the case, consult your installer for advice.
