The current standards and local regulations must be observed. This C-type unit must be installed using the fume exhaust and suction ducts supplied by FERROLI S.p.A. in accordance with UNI-CIG 7129/92. Failure to use them automatically forfeits all warranty and liability of FERROLI S.p.A. - Page 26 DOMINA PLUS F 24 - 30 E FERELLA EXTRA F 24 - 30 MEL Calculation example Here we give an example of the calculation for a separate fume outlet. We recommend inserting a condensate trap on long vertical sections to prevent condensation getting onto the burner and damaging it.

The generator turns off when the desired temperature in the rooms is reached. If the remote control (Ferroli) is used, the system tries to modulate the ambient temperature according to the setting. In this passage the remote control can lower the delivery temperature under the setting to maintain the ambient temperature: in any case, if the ambient temperature exceeds the setting by 1°C the burner switches off and the circulator stays on for post-circulation. - Page 36 DOMINA PLUS F 24 - 30 E FERELLA EXTRA F 24 - 30 MEL Hot water temperature adjustment To set the system delivery temperature, turn the specific knob. It can vary from a minimum of 30°C to a maximum of 65°C. Turning the knob sets the required temperature (clockwise to increase, anticlockwise to decrease) that is shown on the display.
