FUNCTION
Allows water to flow through specially designed coils for maximum heat transfer, while providing protection again
Allows access to the combustion side of the heat exchanger coils.
The fan pulls in air and gas through the venturi (item 5). Air and gas mix inside the fan and are pushed into the b
The gas valve senses the negative pressure created by the fan, allowing gas to flow only if the gas valve is powe
The venturi controls air and gas flow into the burner.
This sensor monitors the flue gas exit temperature. The control module will modulate and shut down the boiler if
This sensor monitors boiler outlet water temperature.
This sensor monitors return water temperature.
The electronic display consists of 7 buttons and a dual line 32-character liquid crystal display.
Allows for the connection of the flue system to the boiler.
Made with metal fibre and stainless steel construction, the burner uses pre-mixed air and gas and provides a wid
BSP water connection that supplies hot water to the system, either 1-1/4" or 2", depending on the model.
BSP water connection that returns water from the system to the heat exchanger, either 1-1/4" or 2", depending o
Threaded pipe connection, 1/2 ", 3/4", or 1", depending on the model. This pipe should be connected to the inco
The SMART Control responds to internal and external signals and controls the fan, gas valve, and pumps to mee
Designed to remove trapped air from the heat exchanger coils.
Allows for the connection of the air intake pipe to the boiler.
The junction box contains the connection points for the mains voltage power and all pumps.
Location from which the heat exchanger can be drained.
The connection board is used to connect external low voltage devices.
Conduit connection points for the low voltage connection board.
Connects the condensate drain line to a 1/2" PVC union.
Provides access to the gas train and the heat exchanger.
Provides direct spark for igniting the burner.
The quartz glass window provides a view of the burner surface and flame.
Manual valve used to isolate the gas valve from the gas supply.
Device that monitors the outlet water temperature. If the temperature exceeds its setting, it will break the control
Used by the control module to detect the presence of burner flame.
Conduit connection points for the mains voltage junction box
Removable panel to gain access to the internal components.
Turns 230 VAC ON/OFF to the boiler.
Used to allow the heat exchanger to be levelled. This is needed for the proper draining of the condensate from t
