B. How the Boiler Operates
Elite FT® condensing technology intelligently delivers
hydronic heating while maximizing eciency. Outlined below
are the features of the system and how they operate:
Stainless Steel Heat Exchanger
The highly ecient stainless steel heat exchanger is designed
to extract all available heat from the supply line before it is
exhausted.
Modulating Combustion System
The combustion system modulates the output of the burner
during operation to match system demand and achieve
the control set point while in operation. The set point can
change by internal or external signals to enhance the overall
performance of the system.
Control
The integrated control system monitors the system and
regulates fan speed to control boiler output. This allows the
boiler to deliver only the amount of heat energy required and
nothing more.
The control can be set to monitor outdoor temperature
through an outdoor sensor to regulate boiler set point. The
system can be further enhanced by installing an indirect water
heater to provide domestic hot water.
The control can regulate the output of multiple boilers
through its cascade system function. The cascade system is
capable of connecting up to eight boilers together in such a
way that they function as one boiler system. This allows for
greater turn down ratios and provides systematic control of
the multiple boilers in an installation to minimize downtime
and maximize eciency.
The cascade system works by establishing one boiler as the
master and the other connected boilers as followers. The
master boiler requires a sensor to provide feedback on set
point temperature in order to adjust heating input from the
connected boilers. Each cascaded boiler will have its own
pump to provide maximum ow and control heat exchanger
ow rate.
Text Display and Operational LED Light Indicators
The display allows the user to change system parameters and
monitor system outputs.
Gas Valve
Senses suction from the blower, allowing gas to ow only if
powered and combustion air is owing.
All Metal Integrated Venturi
Controls air and gas ow into the burner.
Burner
The high grade stainless steel burner uses premixed air and
gas to provide a wide range of ring rates.
Spark Ignition
The burner is ignited by applying high voltage through the
system spark electrode. The spark from the electrode ignites
mixed gas o of the burner.
Supply Water Temperature Sensor
This sensor monitors the boiler outlet water temperature
(System Supply). The control adjusts boiler ring rate so the
supply temperature will match the boiler set point.
Return Water Temperature Sensor
This sensor monitors boiler return water temperature (System
Return).
Flue Sensor
Monitors ue temperature and adjusts ring rate.
Temperature and Pressure Gauge
Allows the user to monitor system temperature and pressure.
Electricaleldconnectionswithterminalstrips
The electrical cover allows easy access to the clearly marked line
voltage and low voltage terminal strips to facilitate wiring the
boiler.
Condensate Collection System
This boiler is a high eciency appliance and will produce
condensate. The condensate collection system has a oat switch
which monitors condensate level and prevents condensate from
backing up into the combustion system. Inside the collection
system is a built in trap which seals the combustion system from
the connected drain. This condensate should be neutralized to
avoid damage to the drainage system or piping.
Outdoor Sensor
Monitors outdoor temperature and adjusts unit set point to
provide greater eciency.
0-10 Volt Input
Allows the installer to connect a BMS (Building Management
System) to control the boiler.
Condensate Flue Check System
The check system prevents heat exchanger exhaust from
backing up into the cabinet.
Pump Service Mode
Allows manual operation of pumps to commission system and
check pump operation.
The Vision II System (Optional)
Allows the user to supply mixed temperatures in up to eight
zones. The Vision II system controls the temperature to each
zone by employing three way mixing valves. The Vision II also
controls the output temperature of the boiler to assure accurate
temperature delivery to all connected zones.
