COMMISSIONING

FILLING THE HOT WATER AND HEATING CIRCUITS

IMPORTANT

The hot water tank must be pressurised before the heating circuit is filled.

1.Close the primary circuit filling valves (11).

2.Open the stop valve (1) and the drawoff tap (8).

When water flows out of the tap, the hot water tank is full and the drawoff tap (8) should be closed.

3.Fill the primary (heating) circuit by opening the valves (11) and pressurising to 1 bar.

BURNER FEATURES

ACV BG 2000-M MODULATING

PREMIX GAS BURNERS

Description of operation:

The BG 2000-M modulating burner continually adjusts output to demand, improving operating efficiency.

The burner tube is coated with metal fibre (NIT) which, in addition to its remarkable heat exchange capabilities, gives greater durability.

The main components are a venturi and one (model 71) or two (model 101) gas valves, technology specially developed by Honeywell for low Nox premix air/gas burners with automatic ignition and ionisation flame detection.

The pressure at the gas valve outlet is equal to the air pressure in the neck of the venturi, less the offset. The fan sucks combustion air through the venturi, into which the gas inlet emerges.

As it passes through, the air produces a pressure differential in the constriction of the venturi and sucks the gas into the venturi outlet. A perfect mix of air and gas then passes through the fan to the burner tube.

This design ensures very quiet and safe operation:

•If there is an air blockage, the pressure differential in the venturi falls, the gas flow diminshes, the flame goes out and the gas valve closes: the burner is in safety shutdown mode.

•If there is a blockage in the chimney outlet, the air flow diminishes, and the same reactions as those described above cause the burner to shut down in safety mode.

•The BG 2000-M burner fitted to the HeatMaster 71 and 101 is regulated by a MCBA controller (Honeywell) which controls burner operating safety as well as temperature modulation.

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.Switch the on/off switch to the ON position.

8.	Set the temperature settings (see pages 15-16).
9.	Check the gas supply pressure (see page 13).

BG 2000-M burners are preset at the factory for natural gas.

10.	When the burner operates, check the chimney connection for
	leaks.
11. After 5 minutes of operation, turn the boiler off and vent the heating
	circuit system again maintaining the water pressure at 1 bar.
12.	Then restart the unit and check the combustion (see page 13).
