Burner
– Constructed of high grade stainless steel, the burner uses premixed air and gas fuel to provide
a wide range of firing rates.
Spark Ignition
– The burner is ignited by applying high voltage through the system spark electrode. This
causes the spark from the electrode to ignite mixed gas from the burner.
Supply Water Temperature Sensor
– This sensor monitors the boiler outlet water temperature (System
Supply). The control adjusts the boiler firing rate so the supply temperature will match the boiler set point.
Return Water Temperature Sensor
– This sensor monitors the boiler return water temperature (System
Return).
Temperature and Pressure Gauge
– Allows the user to monitor system temperature and pressure.
Electrical field connections with terminal strips
– The electrical cover allows easy access to the line
voltage and low voltage terminals strips which are clearly marked to facilitate wiring of the boiler.
Condensation Collection System
– This boiler is a high efficiency appliance, therefore the boiler will
produce condensate. The collection system has a float switch which monitors the condensation level and
prevents condensation from backing up into the combustion system. Inside the collection system there 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.
Flow Protection
– The optional flow switch is designed to protect the boiler in the event of low flow
conditions. The boiler control will also monitor flow through the heat exchanger by monitoring the return
and supply sensors and will shut down the burner before overheating occurs.
Outdoor Sensor
– This sensor monitors outdoor temperature. Data from this sensor is monitored by the
control, which adjusts the unit set point to provide greater efficiency.
Indirect Tank Sensor
(optional) – Monitors storage tank temperature.
