Page 15: Heat Exchanger
HEAT EXCHANGER Heat exchanger is the component which enables transferring the energy produced by the burning of the gas to the water circuit. Different heat exchangers are used in bithermic (24 kW) and monothermic (24 / 28 kW) models. In bithermic heat exchangers which have two water inlets and two water outlets, both central heating and domestic hot water circuits are heated. - Page 16 fig. 4b Monothermic Heat Exchanger HYDROBLOCK Two different types of hydroblocks are used in bithermic and monothermic types. Hydroblock consists of different components depending on the boiler model. The bithermic hydroblock has pump, pressure relief valve (3 bar), discharge tap, filling tap, water pressure switch and water flow sensor on it.

- Page 19 PUMP Pump enables the central heating water circulation in monothermic and bithermic types. Also in monothermic types, it enables heating the domestic water passing through the plate heat-exchanger by causing the central heating water short circuit circulation. Pump is located on the hydroblock and has 3 speed stages. The pump has expansion vessel and termomanometer connections and also an automatic air vent on it.
- Page 20 PRESSURE RELIEF VALVE (3 BAR) Pressure relief valve (3 bar) protects the central heating circuit and the appliance against increasing pressure. When the pressure in the central heating circuit is over 3 bars, the relief valve functions and decreases the pressure (the outlet tap of the 3 bar relief valve should be connected to the drain line with a plastic hose).

Page 21: Plate Heat-Exchanger
fig. 9 Water Pressure Switch PLATE HEAT-EXCHANGER Plate heat-exchanger is the secondary heat-exchanger used in monothermic types for heating the domestic water. In need of domestic hot water, the 3 way electric valve sends the central heating water from the primary heat-exchanger to the plate heat-exchanger. Heat of the central heating water is transferred to the domestic water in the plate heat-exchanger. - Page 22 fig. 11 Water Flow Sensor CENTRAL HEATING AND DOMESTIC HOT WATER (NTC) TEMPERATURE SENSORS The central heating and domestic hot water temperature sensors are NTC (Negative Temperature Coefficient) type. In NTC sensor, temperature and sensor resistance are inversely proportional; the sensor resistance decrease as temperature increases and vice versa.

Page 24: Limit Thermostat
LIMIT THERMOSTAT The limit thermostat used is bimetal type. When water CH from the heat-exchanger exceeds 105°C, the limit thermostat opens and cuts the signal sent to the main board and ensures safety. When the water temperature is below 75 °C, the limit thermostat closes enabling the boiler to operate again after the reset. - Page 25 DIFFERENTIAL AIR PRESSSURE SWITCH (APS) Differential air pressure switch is used in room sealed fan assisted models. It controls the air flow by measuring the pressure differences of the clean air required for burning and flue gas. In case of problems like blockage in the air/flue kit or a strong outer air flow, the air pressure switch shuts down the boiler.

Page 28: Modes Of Operation
MODES OF OPERATION a) Stand-by Mode: when there is no heat demand for central heating or domestic hot water. b) Domestic Hot Water (DHW) Mode: when there is need for DHW (hot water tap is opened), the hall effect sensor on the water flow sensor detects the water flow and signals the main board for DHW delivery. - Page 29 - Domestic hot water can be obtained between 35°C and 60°C. - Domestic hot water safety temperature is 75°C. If the temperature detected by DHW sensor is above 75°C, DHW operation will stop (burner goes off). - DHW operation is possible even if CH anti-cycling time is active. - During DHW operation, min.-max.
- Page 30 - When there is CH demand, ignition starts and ignition state continues until flame is present. - When the ignition state is over, the boiler will operate in normal modulation and reach the set point within the time defined with slope (°C/min). After that, modulation continues. - If the central heating water temperature exceeds 95°C in CH mode, over temperature error (electronic limit) occurs and the boiler will remain in this error mode till water temperature drops to a safe level (80°C).
- Page 31 - Bithermic & Winter Mode: pump runs for the defined over run time (3sec). This is for transferring the remaining energy to the CH circuit. - Bithermic & Summer Mode: if the temperature detected by the CH temperature sensor is more then 75°C, the pump will run for 1 sec., otherwise it will not run.

Page 32: Gas Type Conversion
GAS TYPE CONVERSION : Gas type conversion from LPG to natural gas or from natural gas toLPG must be carried out only by qualified person. - Gas type conversion can be divided in 3 sections: gas pressure adjustments, replacement of the burner injectors and jumper adjusment. - Page 33 fig. 19 Replacement Of The Burner Injectors WARNING:Keep the gas valve on the boiler and electricity supply closed during replacement of the burner injectors. - Shut off the boiler by turning the ON/OFF switch to OFF position and turn off the gas valve on the boiler.

Questions and answers
Boiler won't fire up red light on flame symbol with line across
The E.C.A. Fortius boiler won't fire up when the red light on the flame symbol is on with a line across because this indicates a lockout condition. Lockout conditions, such as no flame, false flame, over-temperature failure, or APS (Air Pressure Switch) faults, disable heat demands. To clear the lockout, the reset push-button must be held for 2 seconds. If the problem persists, a qualified service technician should be contacted.
