STARTUP

FILLING THE DOMESTIC HOT WATER AND
HEATING CIRCUITS
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
10. Carry out the required venting, measurement and setting
procedures.

Emptying the hot water circuit
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 .
