Frequently Asked Questions - Solo 3 PFL 50 Baxi
What type of gas does the Baxi Solo 3 PFL 50 use?
The boiler is designed for natural gas (G20) but can be converted to propane (G31) with a conversion kit. Always consult a qualified installer for conversion.
How do I reset the boiler after a fault?
Press and hold the reset button for 3 seconds. If the fault persists, refer to the error code in the manual. Common issues include low water pressure or lack of gas.
What should the water pressure be?
The ideal pressure is between 1 and 2 bar when cold. If below 1 bar, repressurise using the filling loop. Never operate below 0.5 bar.
How often should I service the boiler?
Annual servicing by a Gas Safe registered engineer is recommended. This includes cleaning the burner, checking flue gas analysis, and inspecting safety devices.

Banging noises often indicate air in the system or limescale buildup. Bleed the radiators first. If persistent, a power flush may be required.
Can I use the boiler for hot water only?

Turn off the boiler and isolate the gas and electricity. Attach a hose to the drain valve, open it, and allow water to drain. Only perform if necessary.
