B. HOW BOILER OPERATES
Mod Con condensing technology intelligently delivers highly efficient hydronic heating while maximizing
efficiency by measuring data from the heating system. Outlined below are the features of the system and
how they operate:
Stainless Steel Heat Exchanger - The highly efficient stainless steel heat exchanger is designed to use
the cold return water from the system and extract the last bit of heat before it is exhausted.
Modulating Combustion System - The combustion system will modulate the output of the burner during
operation to match the system demand and achieve the control set point while in operation. The set point
can change by internal or external signals which 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
system can be further enhanced by installing with 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 efficiency.
The cascade system works by establishing one boiler as the master and the other connected boilers as
followers. The master boiler requires a cascade system sensor and a cascade pump in addition to its own
boiler pump. Each of the follower boilers has an individual pump.
System Display and Operational LED Light Indicators – The display allows the user to change the
system parameters and monitor system outputs.
Gas Valve – Senses suction from the blower, allowing gas to flow only if powered and combustion air is
flowing.
All Metal Integrated Venturi – Controls air and gas flow into the burner.
