COMMISSIONING
FILLING THE HOT WATER AND HEATING CIRCUITS
IMPORTANT
Hot water tank must be pressurised before the heating circuit is filled.
1.Close the primary circuit filling valves (A)
2.Open the stop valve (B) and the drawoff tap (C).
When water flows out of the tap, the hot water tank is full and the drawoff tap (C) should be closed.
3.Fill the primary (heating) circuit by opening the valves (A) and pressurising to 1 bar.
4.Open the automatic air vent located on top of the boiler.
IMPORTANT - the screw cap must be left loose to allow future automatic venting to take place.
5.After venting the air from the system, bring the pressure up to the static head plus 0.5 bar: 1.5 bar = 10m and 2 bar = 15 m.
6.Check that the electrical connection and boiler room ventilation conform to the relevant standards.
7.Set the thermostat between 60 and 90 °C.
8.Switch the on/off switch to the ON position.
9.For gas burner, check the gas supply pressure on starting up.
10.For the oil burner, check the oil supply (and return). Proceed with the necessary venting, measurements and settings.
11.Set the heating control to heat demand. When the burner operates, check the flue gas discharge pipes for leaks.
12.After 5 minutes of operation, vent the primary circuit again maintaining the water pressure at 1 bar.
13.Then restart the unit and check the combustion.
