How do I reset the boiler after a fault?

Press the reset button on the control panel for 2 seconds. If the fault persists, consult the manual for error codes.

What should I do if the boiler loses pressure?

Check the pressure gauge; it should be between 1.0 and 1.5 bar. Use the filling loop to repressurise the system.

How often should the boiler be serviced?

An annual service by a Gas Safe registered engineer is recommended to ensure optimal performance and safety.

Why is there no hot water?

Check if the boiler is in summer mode (hot water only) or if the thermostat is set correctly. Also ensure gas supply is on.

How do I bleed the radiators?

Use a radiator key to open the bleed valve slightly until water comes out, then close it. Check boiler pressure afterwards.

What does the error code F.28 mean?

F.28 indicates ignition failure. Check gas supply and make sure the gas valve is open. If persistent, call a professional.

Can I install the boiler myself?

No, installation must be carried out by a qualified heating engineer in compliance with local regulations.

How do I adjust the heating temperature?

Use the temperature control dial on the boiler panel. Set it between 60-80°C for central heating.

What type of flue does this boiler require?

It uses a concentric flue system (60/100 mm) suitable for balanced flue operation.

How do I clean the boiler exterior?

Wipe with a damp cloth using mild detergent. Do not use abrasive cleaners or spray water directly on the boiler.
