FILLING THE DOMESTIC HOT WATER AND
HEATING CIRCUITS (see illustrations B, G et H)
IMPORTANT
The hot water tank must be pressurised before the
heating circuit is filled.
1. Fill the domestic hot water circuit and bring it up to pressure.
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. After venting the air from the system, bring the pressure up to
the static head plus 0.5 bar: 1.5 bar = 10m -2 bar = 15 m.
5. Check the power connection, the boiler room ventilation, and
ensure that there are no leaks in the flue gas discharge pipes.
6. Set the boiler thermostat to between 60 and 90 °C.
7. Set the Summer/Winter selector to the desired position.
8. Switch the on/off switch to the ON position.
9. Check the oil supply
(and return).
10. Carry out the required venting, measurement and setting
procedures.
STARTING ACV BMV1 AND BMV2 BURNERS
Refer to the ACV BMV1 and BMV2 burner manual supplied with them.
RECOMMENDATION
ACV advises that boilers should be serviced at least once a year.
The burner must be serviced and tested by a competent engineer.
SERVICING THE BOILER (see illustration K)
1. Switch off the power at the mains switch outside the boiler and
shut off the oil supply.
2. Set the on/off switch on the control panel to the OFF position.
3. Remove the top cover of the boiler (2) and take off the top of the
chimney reduction (3).
5. Remove the turbulators (23) from the flue pipes (22) for cleaning.
Change them if in poor condition.
6. Unscrew the burner chamber plate (10).
7. Brush the flue pipes (22).
8. Clean the burner chamber (18) and the burner.
9. Check the condition of the burner chamber plate insulation.
SERVICING THE SAFETY DEVICES
- Check that all thermostats and safety devices are working
properly : boiler thermostat, cut-off thermostat and manually reset
safety thermostat.
-Test the safety valves on the central heating and hot water circuits.
SERVICING THE BURNER
Refer to the ACV BMV1 and BMV2 burner manual supplied with them.
EMPTYING THE BOILER
Water flowing out of the drain cock is extremely
hot and can cause severe burns.
Keep people away from discharges of hot water.
Emptying the heating circuit (see illustration G)
1. Set the on/off switch on the control panel to the OFF position,
turn off the power at the external mains switch and close the oil
feed valve.
2. Close the isolating valves (8).
3. Connect a hose to the drain cock (9).
4. Open the drain cock to empty the primary circuit.
Emptying the hot water circuit (see illustration H)
1. Set the on/off switch on the control panel to the OFF position,
turn off the power at the external mains switch and close the oil
feed valve.
2. Lower the pressure in the heating circuit until the pressure
gauge indicates zero bar.
3. Close the valves (7 and 11).
4. Open valves (9) and (10) (first 9 then 10).
5. Let the water empty into the drain .
For the tank to be emptied, valve (9) must be situated
at ground level.
