3 3.1 START-UP FILLING THE HEATING AND HOT WATER CIRCUITS 1. Fill the domestic hot water circuit and bring it up to pressure. 4 4.1 RECOMMENDATION ACV recommends that boilers should be serviced at least once a year. The burner must be serviced and tested by a competent engineer. 4.2 IMPORTANT The hot water tank must be pressurised before the heating circuit is filled. 2. Fill the heating circuit taking care not to exceed the 2 bar pressure limit. 3. Vent the air from the top of the boiler. 4.
4 4.4 SERVICING SERVICING THE BURNER - Check and clean the burner and ignition electrode. - Check that the safety components are working properly. 4.5 EMPTYING THE BOILER 4.5.1 EMPTYING THE PRIMARY CIRCUIT (central heating): 1 1 1. Switch off the power to the boiler at the mains switch installed by the electrician. 2. Close the isolating valves (1) of the boiler system. 3. Connect a hose to the drain valve (2). Ensure that it is attached properly. 4.

6 TECHNICAL SPECIFICATION Description 1. 2. 3. 4. These atmospheric burners are fitted with a SIT gas valve and an electrically operated relay. This gas valve has been specially developed for atmospheric burners with automatic ignition and ionisation flame detection. Electrically operated gas valves. Upstream gas pressure test point. Pressure regulator Gas burner pressure test point. 1 Advantage • • • No pilot flame, therefore no gas consumption when when the boiler is off.
7 USER GUIDE 7.1 USING THE BOILER 7.1.2 7.1.1 GETTING TO KNOW THE CONTROL PANEL (Fig. 20) Your system is fitted with a heating safety valve set to 3 bar, with a pressure gauge. 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. Ensure that the water in the system is always pressurised.
7 7.1.5 USER GUIDE GAS BURNER - RESETTING If the atmospheric burner is not working: 1. Remove the protective cover. 2. Press the red button to start the burner. 7.2 BOILER ROOM • • • • Keep vents free at all times. Do not store inflammable products in the boiler room. Take care not to store corrosive products near the boiler, such as paints, solvents, chlorine, salt, soap and other cleaning products. If you smell gas, do not switch on the light or light a flame.
