To Next PageTo Next PageWhat to do if the Riello Condexa PRO NA 75 P Boiler generator triggers a thermal safety block?
If the generator triggers a thermal safety block, it could be due to several reasons: * No water: Check correct functioning, the temperature setting, the electrical wiring, and the position of the sensor bulbs. * Modular system adjustment: Check the bleed valve and the heating circuit pressure.
Why is my Riello Boiler heating system cold when the generator is at temperature?
If the generator is at temperature but the heating system remains cold, it could be due to: * Air in the system: Bleed the system. * Pump malfunctioning: Check/unseize the pump, replace the circulator if necessary, and check the electrical connection of the circulator.
What causes an odor of unburnt gas from a Riello Boiler?
An odor of unburnt gas may be caused by issues in the flue gas circuit. Check the gasket seals, ensure there are no obstructions, and verify the combustion quality.
Why isn't my Riello Boiler modular system reaching the set temperature?
If the modular system does not reach the desired temperature, possible causes include: * A dirty boiler: Clean the combustion chamber. * Insufficient burner capacity: Check and adjust the burner. * Modular system adjustment issues: Check correct functioning and the temperature setting.
Why does the system safety valve on my Riello Condexa PRO NA 75 P trip frequently?
Frequent tripping of the system safety valve may be due to: * A faulty system safety valve: Check its calibration or efficiency. * Incorrect circuit pressure: Check the circuit pressure and the functioning of the pressure reducer. * Expansion tank issues: Check the efficiency of the expansion vessel.
What causes irregular combustion in a Riello Condexa PRO NA 75 P Boiler?
Irregular combustion can stem from several factors: * Burner gas pressure: Check the temperature setting. * Diaphragm installation: Check the diameter. * Dirty components: Check the condition of the burner and exchanger and clean them if necessary. * Obstructed exchanger passages: Check passage cleaning. * Faulty fan: Check operation.
What to do if the circulator of Riello Boiler doesn't start?
If the circulator fails to start, it might be caused by pump malfunctioning. You should check/unseize the pump, replace the circulator if needed, and inspect the electrical connection of the circulator.
Why does my Riello Condexa PRO NA 75 P Boiler have ignition delays with pulsations to the burner?
Ignition delays with pulsations to the burner can be caused by: * Incorrect burner gas pressure: Check the temperature setting. * Issues with the ignition electrode: Check its positioning and condition.
What to do if the Riello Condexa PRO NA 75 P Boiler burner doesn't start upon consent of the modular system control?
If the burner does not start when the modular system control allows it, check the gas valve for the presence of 120Vac voltage on the gas valve terminals and inspect the wiring and connections.
Why does the Riello Condexa PRO NA 75 P modular system get dirty so quickly?
If the modular system becomes dirty very quickly, it could be due to combustion issues. Check the combustion controls.
