The Prestige uses a microprocessor
electronic control module that automati-
cally adjusts blower speed and gas flow
rate to modulate boiler firing rate to
closely match boiler output to space
heating or DHW heating demand. The
module responds to signals from the
room thermostat, supply and return
water temperature sensors, flue temper-
ature sensor, domestic hot water aquas-
tat and outdoor temperature sensor.
High grade stainless steel burner uses pre-mixed air and gas
providing a 25% to 100% modulating firing rate. The Prestige
burner features a long life, quiet operation, reliable spark ignition,
and clean combustion for low NOx applications.
The blower, gas valve and venturi provide the proper gas and air
mixture for precise combustion. The blower pulls in air and gas
through the venturi. The air and gas mix inside the blower and
are pushed into the burner for combustion. The gas valve sens-
es suction from the blower and allows gas to flow only if com-
bustion air is flowing.
