BURNER FEATURES
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.
