Frequently Asked Questions - Avanta Exclusive 39C Remeha

How do I reset my Remeha Avanta Exclusive 39C boiler?

Press and hold the reset button (usually a small recessed button) for 3-5 seconds until the display shows normal operation. If the boiler fails to ignite, check gas supply and pressure. Refer to manual for error codes.

What does error code EA mean on the display?

Error code EA indicates a flame loss or ignition fault. This can be due to gas supply issues, blocked flue, or faulty ignition electrode. Check gas valve and reset the boiler. If persistent, contact a Gas Safe engineer.

How to check the boiler pressure?

The pressure gauge is on the front panel. Normal pressure is between 1.0 and 1.5 bar when cold. If below 0.5 bar, top up using the filling loop. Do not exceed 2.0 bar.

Why is my boiler making a banging noise?

Banging noises are often caused by air in the system or kettling (limescale buildup). Bleed radiators to remove air. If noise persists, consider descaling or flushing the system.

How often should I service the boiler?

Annual servicing by a qualified Gas Safe engineer is recommended to ensure safe and efficient operation, typically before winter. This includes cleaning the heat exchanger and checking safety devices.

Can the boiler be used with smart thermostats?

Yes, the Avanta Exclusive 39C is compatible with many smart thermostats via OpenTherm or on/off connection. Consult the manual for wiring and setup instructions.

Why is the hot water temperature fluctuating?

Fluctuations may be due to low flow rate, partially closed valve, or faulty temperature sensor. Check that DHW flow is at least 8 L/min. Also ensure the boiler is set to comfort mode.

How do I top up the system pressure?

Locate the filling loop (usually a braided hose with two valves). Slowly open both valves while watching the pressure gauge. Close when pressure reaches 1.0-1.5 bar. Vent air from radiators after refilling.

What does the 'SERVICE' message mean?

The SERVICE reminder indicates that annual maintenance is due. This is a programmable notification. Contact an engineer to perform the service and reset the message via the menu.

How to bleed a radiator with this boiler?

Turn off the boiler and wait for pipes to cool. Use a radiator key to open the bleed valve slightly until water (no air) comes out. Close valve and check boiler pressure; top up if needed.

5 DISABLING THE BOILER

10°C

LT.AL.W7H.000.217

The boiler must be disabled before any maintenance or repairs are carried out. If the central heating system is not used for a long time (during the holidays, for instance, or periods of milder weather) it is advisable to disable the boiler.

1. Disable boiler with frost protection, during longer periods of non-use

• Set the room thermostat to a low temperature, e.g. 10^ ,
• Switch setting to (Eco mode), this will switch off the heat retention function.

Now the boiler will only start working to protect itself against freezing.

With an external frost protection connected, the boiler can also prevent the central heating system from freezing.
