Frequently Asked Questions - RX TP SIME
How to bleed air from radiators?
Open the bleed valve with a suitable key until water comes out without air bubbles. Then close it. Check the boiler pressure after bleeding.
What to do if the boiler does not ignite?
Check the gas supply and electricity supply. Ensure the gas valve is open and the room thermostat is set correctly. If the problem persists, contact a professional.
How to read the heating circuit pressure?
Pressure should be between 1 and 2 bar. If it is below 1 bar, refill via the filling valve. If it exceeds 3 bar, bleed a radiator.
How often should the boiler be serviced?
Maintenance must be carried out mandatorily every year by a qualified professional. This ensures the safety and efficiency of the appliance.
What does the red light mean?
A red light generally indicates a fault or triggered safety feature. Consult the manual to identify the error code or contact after-sales service.
How to fill the heating circuit?
Use the filling valve located under the boiler. Open it slowly and monitor the pressure gauge until it reaches about 1.5 bar. Then close it and bleed the air.
The boiler is making noise, what to do?
Knocking noises can come from air in the radiators or pressure too high. Bleed the radiators and adjust the pressure. If the noises persist, call a professional.
Can the boiler be used without a room thermostat?
Yes, but regulation will be less precise. The thermostat maintains a constant temperature and saves energy. It is recommended to use it.
How to repair a leaking boiler?
Close the gas supply valve and cut off the electrical supply. A leak may come from a worn seal or excessive pressure. Call a professional without delay.
Where to find the boiler serial number?
The serial number is on the rating plate on the side or inside the front panel. It is required for any spare part or assistance request.
