What to do if the temperature is too high in Intergas Combi Compact HRE 28/24?
If your Intergas Boiler is overheating, possible solutions include: * Removing air from the installation. * Ensuring the pump is running. * Verifying sufficient flow in the installation, checking that radiators are open, and ensuring the pump setting isn't too low. * Checking if the flow switch is sticking.
What causes a poor flame signal in Intergas Boiler?
If your Intergas Boiler has a poor flame signal, check for a blocked condensate drain and check the adjustment of the gas valve.
Why is there no flame signal in my Intergas Boiler?
If your Intergas Boiler is not showing a flame signal, make sure the gas tap is open, check for correct ignition gap, ensure proper gas supply pressure, and verify the gas valve or ignition unit is powered.
