ACV BG 2000-S PREMIX GAS BURNERS

Description

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 60 and 70) or two (model 100) 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-S burner fitted to the HeatMaster 60, 70 and 100 is controlled by a Honeywell module which controls burner operating safety.

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