Frequently Asked Questions - Xtrafast 96 Glow-worm
What is the recommended boiler pressure?
The recommended water pressure is between 1 and 1.5 bar when cold. If it drops below 1 bar, you may need to repressurize the system using the filling loop.
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 display and consult the manual or contact a qualified engineer.
What does error code E01 mean?
Error code E01 indicates a flame detection fault. This may be due to a gas supply issue or a faulty ignition electrode. Contact a Gas Safe engineer.
How often should the boiler be serviced?
The boiler should be serviced annually by a qualified engineer to ensure safe and efficient operation. This is also required to maintain the warranty.
Can I use the boiler if the pressure gauge shows red?
No, if the pressure gauge is in the red zone (above 2.5 bar), the system is overpressurized. Bleed a radiator or reduce pressure using the drain valve. If it persists, call an engineer.
What type of gas does the Xtrafast 96 use?
The boiler is factory-set for natural gas but can be converted to LPG by a qualified engineer using a conversion kit.
How do I adjust the hot water temperature?
Use the temperature control knob or digital interface. For hot water, set between 40°C and 60°C. For central heating, between 60°C and 80°C.
Why is the boiler making a banging noise?
Banging noises (kettling) are often caused by limescale buildup or trapped air. Bleed the radiators and consider powerflushing the system. If the noise continues, contact a heating engineer.

Glow-worm typically offers a 2-year standard warranty, extendable up to 10 years if registered and serviced annually. Check your installation documents for details.
