Frequently Asked Questions - Gas 610 ECO Remeha

How to start up the Gas 610 ECO boiler?

First check the hydraulic pressure (min 0.8 bar). Open the gas valve and make sure the thermostat is calling for heat. Start the pump then turn on the main switch. The code display shows the sequence: 5 (waiting), 1 (ventilation), 2 (ignition), 3 (boiler in service).

What to do in case of a flashing error code on the display?

Note the exact 3-digit code (including flashing and dots). Before pressing the Reset button, check the basics: gas valve open, sufficient pressure, switch on. If the problem persists, contact your installer.

How to purge the heating system?

Set the boiler to call for heat, open all radiator valves, let the temperature rise to 80°C, then stop the boiler and circulation pump. Wait 10 minutes, bleed the radiators and air vents, then check the pressure and add water if necessary up to 1.5 bar.

What is the recommended hydraulic pressure?

The minimum pressure is 0.8 bar. When filling, it is advised to go up to 1.5 bar. Check the pressure regularly on the pressure gauge.

What does code 'b' on the code display mean?

Code 'b' (with a dot) indicates a temporary blocking mode, not a fault. The boiler tries to restart automatically after a short pause.

How to adjust the flow temperature?

Use the Mode button to enter adjustment mode (press until a fixed dot appears on the code display). Select the desired parameter with Step, adjust with + or -, then press Store to save. The factory temperature is 90°C.

What to do in case of gas odor?

Immediately close the gas shut-off valve. Do not operate any electrical switch. Ventilate the room and contact the gas utility company or your installer.

How often should the boiler be serviced?

It is essential to have the boiler serviced at least once a year by a qualified installer, even during the warranty period. Regular maintenance ensures safety and performance.

Can I modify the boiler settings myself?

As a user, you must not modify anything on the boiler yourself. Only settings accessible via user mode (such as the flow temperature) are allowed. For any other modification, consult your installer.

What to do if the boiler does not start after several attempts?

Check the basics: gas valve open, thermostat set high enough, switch on, sufficient hydraulic pressure. If the problem persists, note the error code and contact your installer. Do not press Reset repeatedly.

These user guidelines contain useful and important information for the correct operation and maintenance of the Remeha Gas 310/610 ECO. Furthermore, important instructions are given to ensure safe and trouble-free boiler operation. Read these instructions carefully before putting the boiler into operation, familiarise yourself with

its operation and strictly observe the instructions given. Your installer usually supplies user guidelines for the entire installation. Follow at first these guidelines (if available).

Remark: As a user you are not allowed to change any part of the boiler.

A venturi (6) is placed on the inlet side of the fan (7), see fig. 01. On heat demand the fan starts to pre-purge. Combustion air is drawn into the boiler through the air inlet (1). The incoming air is mixed optimally in the venturi and later in the fan with the gas from the multiblock (10). The homogeneous gas / air mixture is brought to the burner by the fan. Depending on demand (under the dictates of flow/return sensor and other external/internal control inputs) the boiler output is controlled.

The mixture is initially ignited by the combined ignition/ionisation probe (8), which monitors the state of the flame. The products of combustion in the form of hot flue gases are forced through the cast aluminium heat exchanger (11) transferring their heat to the system water (the flue gas temperature is reduced to approxi-

mately 5^ C above the temperature of the system return water). If the flue gas temperature decreases below dew point ( 55^ C) the water vapour in the flue gases will begin to condense out in the boiler, transferring its latent heat into the system water, increasing the output of the boiler without increasing the gas consumption.

Condensation formed within the boiler and flue system is discharged from the boiler to an external drain via the drain pan / siphon (17) supplied. The flue gases turn in the drain pan (16) and are discharged vertically through the flue gas connection (2) to atmosphere.

* For the Remeha Gas 610 ECO this information applies to each boiler module.

An intelligent, advanced boiler control* ('abc®') continuously monitors the boiler conditions, varying the heat output to suit the system load. The control is able to react to external "negative" influences in the rest of the system (flow rates, air / gas supply problems) maintaining boiler output for as long as possible without resorting to a lock out condition. At worst the boiler will reduce

2. Check the water pressure in the installation (min. 0.8 bar). Fill up when necessary.
3. Open the main gas cock.
4. Put the boiler control to heat demand.
5. Start the circulation pump.
6. Switch on the electrical supply to the boiler and the on/off switch on the instrument panel.
7. The following operation course shall successively appear on the code-display:

5 = Waiting mode; the fan runs and the boiler waits until sufficient air transport is established (air pressure switch open or closed).
I = Pre-purging.
2 = Ignition of the gas/air mixture.
3 = The burner is firing.

The boiler now operates.

If this fails to work, switch the boiler to manual operation (see Chapter "Operation" from the Technical Information), set the flow temperature to the desired value and contact your installer.

1. First follow the guidelines that your installer supplied for the entire installation. If not available: follow the instructions below.
2. Turn off the boiler control.
3. Close the main gas cock.
4. Switch off the electrical supply.

Attention! Think of the risk of freezing!

If temperatures are low, it is recommended to run the central heating installation at a reduced temperature to avoid freezing up.

VENTING OF THE INSTALLATION

1. Put the boiler control to heat demand.
2. Open all the radiator valves.
3. Run the installation up to about 80^ C.
4. Switch off the electrical supply to the boiler.
5. Wait for approximately 10 minutes.
6. First vent the installation on all the vent points (boiler, radiators, etc.).
7. Check the water pressure and, if necessary, fill up to design system pressure; entirely fill the filling hose before connecting it to the installation.

8. Put the boiler into service again.

Repeat venting procedure, if necessary.

Attention!

A poorly vented installation may cause water flow problems and air noise in the boiler, the pipework and the radiators.

TROUBLE SHOOTING

Before calling in the installing engineer, first check if:

• The gas cock is open
• The maximum operating temperature setting is high enough
• The boiler control has been correctly set
• The main switch is on
• A sufficient water flow is possible (the radiator valves are entirely opened)
• The water pressure is sufficient (> 0.8 bar).

Note down the failure message before resetting

(3 digits, blinking and dots included). Reset the failure by pressing the reset-key on the instrument panel. If the boiler failure is immediately repeated, contact the installing engineer, stating the failure message.

Attention!

Do not forget that your central heating installation needs servicing once a year.

On gas smell: close main gas cock and warn gas company or installer.
