FILLING THE DOMESTIC HOT WATER AND
HEATING CIRCUITS
IMPORTANT
Before pressurizing the central heating circuit, you should
first put the domestic hot water tank under pressure.
FILLING THE DOMESTIC HOT WATER CIRCUIT
1. Open the filling valve (1) and the drawoff tap (2).
2. When water flows out of the tap, the hot water tank is full and the
drawoff tap (2) should be closed.
PRELIMINARY FILLING OF THE HEATING CIRCUIT
1. Open the stop valves (A).
2. Make sure that the draining valve (D) is fully closed.
3. Open the filling valves (B and C) to start filling the primary circuit
with mains water until you reach an approximate pressure of 1,5 bar
in the system.
4. Bleed the boiler and the whole system using the automatic air bleed
valve located on top of the appliance.
STARTING UP THE BOILER
STARTING THE BURNER
1. Set the boiler master switch on ”ON” and the summer/winter switch
on the ” ”. symbol.
2. Rotate the boiler control thermostat clockwise to generate a heat
demand.
3. Possibly increase the set temperature of the room thermostat, if in-
stalled.
ADJUSTING THE COMBUSTION
1. Refer to the starting up instructions detailed in the technical manual
of the burner.
2. Adjust CO2 as described in the Starting up paragraph of the burner.
3. Check temperatures and CO level.
BLEEDING THE HEATING CIRCUIT
1. Bleed the heating circuit again to restore a 1.5 bar pressure.
2. Repeat the sequence until complete evacuation of the air contained
in the circuit.
