Warning Removal and disposal of the boiler must be car ried out by a qualified installer in accordance with local and national regulations.

Warning If the mains lead is damaged, it must be replaced by the original manufacturer, the manufacturer's dealer or another suitably skilled person to pre vent hazardous situations from arising.

1 Safety

114494 - v.05 - 06022018 9

Warning Always disconnect the mains supply and close the main gas tap when working on the boiler.

Warning Check the entire system for leaks after mainte nance and servicing work.

Danger For safety reasons, we recommend fitting smoke and CO alarms at suitable places in your home.

Caution

Make sure the boiler can be reached at all times. The boiler must be installed in a frost-free area. If the power cord is permanently connected, you must always install a main bipolar switch with an opening gap of at least 3 mm (BS EN 60335-1). Drain the boiler and central heating system if you are not going to use your home for a long time and there is a chance of frost. The frost protection does not work if the boiler is out of operation. The boiler protection only protects the boiler, not the system. Check the water pressure in the system regular ly. If the water pressure is lower than 0.8 bar, the system must be topped up (recommended water pressure between 1.5 and 2 bar).

Important Keep this document near to the boiler.

Important Only remove the casing for maintenance and re pair operations. Refit all panels when mainte nance work and servicing are complete.

Important Instruction and warning labels must never be re moved or covered and must be clearly legible throughout the entire service life of the boiler. Damaged or illegible instructions and warning stickers must be replaced immediately.

Important Modifications to the boiler require the written ap proval of Remeha.

4.1 General description

4 Description of the product

The Gas 210 ECO PRO is a free-standing gas boiler with the following characteristics:

High-efficiency heating. Cast aluminium heat exchanger. Limited emissions of polluted substances. Has transport wheels as standard.

The following boiler types are available:

Gas 210 ECO PRO - 210-80 Gas 210 ECO PRO - 210-120 Gas 210 ECO PRO - 210-160 Gas 210 ECO PRO - 210-200

4.2

Operating principle

4.2.1

The boiler is equipped with a casing that also serves as an air box. The fan draws in the combustion air. The gas is injected into the venturi and mixed with the combustion air. The fan speed is controlled on the basis of the settings, the heat demand and the prevailing temperatures measured by the temperature sensors. The gas/air ratio control ensures an accurate mixture of the required amounts of gas and air. This provides optimum combustion over the entire heat input range. The gas/air mixture goes to the burner, where it is ignited by the ignition electrode.

Gas/air regulation

4.2.2 Control

On/off control The heat input varies between the minimum and the maximum values on the basis of the flow temperature set on the boiler. It is possible to connect a 2-wire on/off thermostat or a power stealing thermostat to the boiler. Modulating control The heat input varies between the minimum and the maximum values on the basis of the flow temperature determined by the modulating con troller. The boiler output can be modulated with an appropriate modulat ing controller. Analogue control (0 - 10 V) The heat input varies between the minimum and the maximum values on the basis of the voltage present at the analogue input.

4.2.3 Circulation pump

The boiler does not have a built-in pump, but does have a built-in pump switch. A circulating pump can be installed on the connector of the stand ard control PCB. This can be an on/off pump or a modulating pump (with 0

- 10 V control).

The pump settings can be changed.

5.2.2 Location of the boiler

The standard inspection and maintenance operations to the boiler are car ried out from the front. The inspection hatch on the heat exchanger is also located here. The hydraulic connections and the flue gas outlet are located at the front of the boiler. The control panel housing is also on the front of the boiler.

Use the guidelines and the required installation space as a basis for de termining the correct place to install the boiler. When determining the correct installation space, take account of the permitted position of the flue gas discharge and/or air supply outlet. Ensure that there is sufficient space around the boiler for good access and ease of maintenance.

Danger It is forbidden to store, even temporarily, combustible products and substances in or near the boiler.

Caution

The boiler must be installed in a frost-free area. The boiler must have an earthed electrical connection. A connection to the drain must be present for the condensate drain close to the boiler. A technical clearance of at least 600 mm is required at the front (service side) of the boiler. However, we recommend that the clearance is at least 1000 mm. We recommend a clearance of at least 400 mm above the boiler. At least 50 mm on the lefthand side and 250 mm on the right-hand side.

Caution If the power supply cable is permanently connected, you must al ways install a main bipolar switch with an opening gap of at least 3 mm (BS EN 60335-1).

6.2.1 Rinsing the system

The installation must be cleaned and flushed in accordance with BS 7593 (2006) and BSRIA BG 33/2014.

Before a new boiler can be connected to an existing or new system, the entire system must be thoroughly cleaned and flushed. This step is abso lutely crucial. The flushing helps to remove residue from the installation process (weld slag, fixing products etc.) and accumulations of dirt (silt, mud etc.)

Important Flush the system with a volume of water equivalent to at least three times the volume of the system. Flush the DHW pipes with a volume of water equivalent to at least 20 times the volume of the pipes.

Important Due to the presence of an aluminium heat exchanger, suitable chemicals and the correct use of these chemicals should be dis cussed with specialist water treatment companies.

6.2.2 Connecting the heating circuit

1. Remove the dust cap on the CH flow connection terminal.

2. Remove the dust cap on the central heating return connection.

3. Attach the outlet pipe for central heating water to the central heating flow.

4. Attach the inlet pipe for central heating water to the central heating return.

5. Connect a safety valve to the boiler's flow connection.

6. Connect the pump to the boiler's return connection.

Always connect the boiler in a way that will guarantee the water flow through the unit during operation. When the boiler is used in a system with two return pipes, the return pipe must be used as a cold return. The sec ond return pipe is then used as a hot return. Contact us for more informa tion.

6.4.6 Additional guidelines

Installation

For installing the flue gas outlet and air supply materials, refer to the in structions of the manufacturer of the relevant material. After installation, check at least all flue gas outlet and air supply parts for tightness.

Warning If the flue gas outlet and air supply materials are not installed in accordance with the instructions (e.g. not leak-proof, not correctly bracketed), this can result in dangerous situations and/or physical injury.

Make sure that the flue gas outlet pipe towards the boiler has a sufficient gradient (at least 50 mm per metre) and that there is a sufficient conden sate collector and discharge (at least 1 m before the outlet of the boiler). The bends used must be larger than 90° to guarantee the gradient and a good seal on the lip rings.

Condensation

Direct connection of the flue gas outlet to structural ducts is not permit ted because of condensation. If condensate from a plastic or stainless steel pipe section can flow back to an aluminium part in the flue gas outlet, this condensate must be dis charged via a collector before it reaches the aluminium.

See Manual for the control panel

8.2

8.3

Shutdown

If the central heating is not due to be used for a long period of time, it is recommended that the boiler be disconnected from the power supply.

1. Turn the on/off switch to the off position.

2. Switch off the boiler's electrical connection.

3. Shut off the gas supply.

4. Keep the area frost-free.

Caution In the event of low temperatures, we recommend that the installa tion continues to operate at a lower temperature. This will prevent freezing.

Frost protection

Caution Drain the boiler and central heating system if you are not going to use your home or the building for a long time and there is a chance of frost.

Set the temperature control low, for example to 10 °C.

If there is no heat demand, the boiler will only switch on to protect itself against frost.

If the temperature of the central heating water in the boiler drops too low, the built-in boiler protection system is activated. This system works as fol lows:

If the water temperature is lower than 7 °C, the heating pump switches on. If the water temperature is lower than 4 °C, the boiler switches on. If the water temperature is higher than 10℃, the boiler shuts down and the circulation pump continues to run for a short time.

To prevent the system and radiators freezing in frost-sensitive areas (e.g. a garage), a frost thermostat or outside sensor can be connected to the boiler.

Caution

The frost protection does not work if the boiler is out of opera tion. The boiler protection only protects the boiler, not the system.

10 Maintenance

10.1 General

The boiler does not require a lot of maintenance. Nevertheless, the boil er must be inspected and maintained periodically. Sweep the chimney at least once a year or more often, depending on the country's applicable regulations. Always check the combustion when the chimney is swept. Perform the standard checking and maintenance procedures once a year. Perform the specific maintenance procedures if necessary.

Caution

Maintenance operations must be completed by a qualified in staller. Replace defective or worn parts with original spare parts. An annual inspection is mandatory.

Important Adjust the frequency of inspection and service to the conditions of use. This applies especially to boilers in constant use (for specific processes).

Important The water pressure is shown on the display of the control panel.

The water pressure must be at least 0.8 bar

2. If the water pressure is lower than 0.8 bar, top up the central heating

system.

10.2.2 Checking the water quality

1. Fill a clean bottle with some water from the system/boiler from the

filling and drain cock.

2. Check the quality of this water sample or have it checked.

See More information is available in our Water quality instructions. This manual forms part of the set of documents supplied with the boil er. Always adhere to the instructions in the aforementioned docu ment.

10.2.3 Checking the ionisation current

1. Check the ionisation current at full load and at low load. The value is stable after 1 minute.

2. Clean or replace the ionisation/ignition electrode if the value is lower

than 4 µA.

10.2.4 Check the flue gas outlet/air supply connections

1. Check the flue gas outlet and air supply connections for condition

and tightness.
