Page 12: Limit Thermostat
ECOFEL BOILER SERVICE MANUAL 6.11 Limit Thermostat: It is mounted on main heat exchanger outlet pipe via a clip. It prevents damage to the boiler due to overheat. Limit thermostat shuts down the boiler when water temperature at main heat exchanger outlet reaches 102ºC (±4ºC). -
Page 13: Flow Limiter
ECOFEL BOILER SERVICE MANUAL 6.15 Flow Limiter: Function of the flow limiter is to reduce the water flow at the inlet of usage water heat exchanger. With its o-ring inner structure, it limits the quantity of water flowing into the boiler for heating with 10 l/min. 6.16 Combustion Chamber: The walls of the combustion chamber are bended from sheet metal so as to allow the placement of mineral wool. -
Page 14: Safety Valve
ECOFEL BOILER SERVICE MANUAL 6.19 Safety Valve: Its function is to protect the heater piping and the boiler against pressure increases due to volume increase of the heated water. If the water pressure in the heater piping exceeds 3 bars, the spring in the safety valve pushes the valve and opens automatically. Thus, the pressure in the piping is reduced. -
Page 15: Operation In Heater Mode
ECOFEL BOILER SERVICE MANUAL 7. Operation in Heater Mode: When the boiler is in the heater operation mode it checks all circuit components. If there is water pressure of more than 0.8 bar in the boiler, circulation pump starts working. The main card compares the heating water temperature data coming from the stream sensor with the temperature set by the user via the heater temperature adjustment button on the front panel. - Page 16 ECOFEL BOILER SERVICE MANUAL 8. Operation in Usage Water Mode: When a hot water tap is turned on while the boiler is in heater or usage water mode and when water flow rate from the flow control switch is more than 0.3 bar (2.7 l/min), the wheel within the flow control rotates and informs the flow sensor.
