Part 2 - Before You Start
Condensate Collection System
This boiler is a high efficiency appliance and will produce condensate.
The condensate collection system has a float 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 efficiency.
0-10 Volt Input / 4-20 mA Input (with Optional Analog Clip-In
Board, part # 3319457)
Allows the installer to connect a BMS (Building Management System)
to control the boiler.
Condensate Trap and Air Pressure Switch
The condensate trap and air pressure switch prevent condensate and
heat exchanger exhaust from backing up into the boiler.
Pump Service Mode
Allows manual operation of pumps to commission system and check
pump operation.
Internal By-Pass Valve
Protects the boiler from damage in low flow conditions.
Internal ECM Pump
The internal ECM Pump uses less electricity than standard pumps,
providing high performance operation.
B. Optional Equipment
