Refer to another manual or other pages in this instruction manual. with the NBN D standard. . Safety thermostat with manual reset ( °C). 6. See at the end of this manual. INDEX Please, read carefully this manual before installing and .. standards (in Belgium: NBN D), the local energy.

All horizontal pipe runs must fall to the boiler to prevent condensation water escaping from the terminal. This kit comprises: Pressure reducing valve If the mains water pressure exceeds 6 bar, a pressure reducing valve calibrated to 4. The expansion vessel is not included. The safety group of the water tank must be approved by ACV and calibrated to 7 bar; the group's valve discharge must be connected to the drain.

Hot water expansion vessel Installing a hot water expansion vessel will prevent any risk of excess pressure due to water hammer or pressure fluctuations. Hot water circulation If the water tank is a long way from the point of use, installing a closed recirculation circuit can ensure a faster hot water drawoff at any time.

B Wiring for the MV boiler Fig. Burner connection Key to wiring B. F1 Min. The burner's output is constantly adjusted to suit the fluctuating demand for heat, thus optimising operating efficiency.

Conversion kit supplied with the boiler comprises: - Orifice s. This creates a vacuum P1 at the venturi neck. R 5 C P3 The difference in pressure between the neck of the venturi and the outlet from the gas valve now draws gas through the venturi. P4 P2 Fig.

Starting sequence: Fig. After a 15 second pre-purge the gas valve opens simultaneously with the ignition. Provided an ionisation current is detected inside the first 5 seconds, combustion continues normally until heat is no longer called for. Otherwise, the gas valve closes and the fan stops; the burner is now shut down.

Ionisation Ignition Gas valve opens If the burner shuts down: 1. The burner indicator lamp lights up on the control panel and on the burner. Fan 15s 2. Press the burner reset button on the control panel. Turn the boiler off for several seconds at the main switch, then restart the the boiler. Gas tube Fig. This tube is covered with metal fibres NIT.

This enhances the distribution of the flame, increasing its life and significantly reducing pollutant emissions. The tube is also designed to withstand propane combustion. For safety reasons it is essential that you isolate the power supply and the gas supply valve before carrying out any work on the burner. Dismantling the burner 1. Remove the burner cover. Disconnect the gas connector and the electrical plugs of the burner.

The offset 4 is set at the factory and requires no adjustment. Nevertheless ACV recommends that you check this setting.

Refer to the table of setting parameters. You should contact your installer should you find any significant deviation. Disconnect the air supply pipe from the venturi.

Take off the burner chamber plate by undoing the two retaining nuts. Burner re-assembly The burner is re-assembled in the reverse order of dismantling Step 4 to Step 1.

Adjust the speed of the fan according to the parameters Start, Min. The potentiometers on the p. Start, Min. After dismantling the burner, check the condition of the ignition refer to Fig.

Replace these items if necessary. Check the condition of the tube 5. Re-assemble the burner and check burner ignition. Check the gas connection for leaks. Check the combustion parameters. Boiler servicing and checking must be carried out by a qualified engineer. Fill the hot water circuit and pressurise it. Fill the heating circuit - do not exceed a pressure of 2 bar. Vent the air in the top of the boiler.

Once you have vented the system, return the pressure to static pressure plus 0. Isolate the boiler from the electrical supply at the switch on the external control box, and close the gas supply valve. Remove the boiler cover 2 and dismantle the upper section of the chimney reducer 3. Remove the baffles 24 from the flue ways 23 and clean them. Replace these items if worn.

Remove the burner cover and burner. Brush the flue ways Clean the combustion chamber 20 and the burner. Check the condition of the seal on the burner chamber plate.

Check the gas supply connection and ensure that it is free from leaks.

Check the electrical connection to the boiler and the boiler room ventilation, and ensure that the flue gas discharge pipes and the burner chamber plate are properly gas tight. Keep all persons away from running hot water. Carry out the necessary venting operations, measurements and settings. Draining the heating circuit refer to Fig. Close the isolating valves 8 in the heating circuit. Connect a flexible tube to the drain cock 9. Open the drain cock 9 to drain the heating circuit.

Draining the hot water circuit refer to Fig. Release the pressure in the heating circuit until the pressure gauge reads zero.

Close the tap 7 and the isolating valve Open the drain cock 9 and air vent 10 first 9 then Allow the hot water circuit to discharge to the drain. The drain cock 9 must be at ground level for the circuit to drain fully. The outlet temperature can be set between 20 and The boiler increases or lowers power as a function of instructions. Page Control Panel The symbols located above the function keys indicate their current function. Pressing on any key will display the current status of the boiler and the current command code.

If there is a malfunction, the corresponding code continues to be displayed. Page Parameter Display 1 time to return to the current operating mode. The symbol flashes.

Page 14 - Press the - key until the OFF symbol is displayed. Page 15 - Starting from the current operating status, press key - The symbol and the current temperature are displayed.

About this book

Page Hydraulic Specifications To obtain other volumes, multiply the volume of the system by one of the factors: 0. Belgium:the cross-section of the aeration vents, which are compulsory in the room in which the boiler is installed, must comply with the NBN D standard.Nbn d ebook download; scbcd exam study kit ebook. Nonlinear Optics 7. Check the tightness of the flue gas pipe.

If the burner does not operate, isolate the boiler's electrical supply at the switch on the external control box before removing the front panel of the casing. Each flue way has baffles made of special steel designed to improve the heat exchange and reduce the flue gas outlet temperature. Please contact your installer for further information about chimney lining.
