LP- 276 REV. 9.4.14
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 supplied 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 sensor and will shut down the burner before
overheating occurs.
System Pipe Sensor – This sensor is designed to be used in a cascade system. When placed on the supply line feeding the storage
tank, the system pipe sensor measures the temperature of return water and communicates with the control system to modulate the
firing rate of the connected boilers.
Indirect Tank Sensor (optional) – Monitors storage tank temperature.

PART 3 – PREPARE BOILER LOCATION
Carefully consider installation when determining boiler location. Please read the entire manual before attempting installation. Failure to
properly take factors such as boiler venting, piping, condensate removal, and wiring into account before installation could result in
wasted time, money, and possible property damage and personal injury.
A. BEFORE LOCATING THE BOILER
Incorrect ambient conditions can lead to damage to the heating system and put safe operation at risk. Ensure that the boiler installation
location adheres to the information included in this manual. Failure to do so could result in property damage, serious personal injury, or
death.
Failure of boiler or components due to incorrect operating conditions IS NOT covered by product warranty.
1. Installation Area (Mechanical Room) Operating Conditions
• Ensure ambient temperatures are higher than 32
