Warning
Do not touch the flue gas pipes. Depending on
the boiler settings, the temperature of the flue gas
pipes can rise to over 60°C.
Warning
Do not touch radiators for long periods. Depend
ing on the boiler settings, the temperature of the
radiators can rise to over 60°C.
Warning
Be careful when using the domestic hot water.
Depending on the boiler settings, the temperature
of domestic hot water can rise to over 65°C.
Warning
The use of the boiler and the installation by you
as the end-user must be limited to the operations
described in this manual. All other actions may
only be undertaken by a qualified fitter/engineer.
Warning
The condensation drain must not be changed or
sealed. If a condensate neutralisation system is
used, the system must be cleaned regularly in ac
cordance with the instructions provided by the
manufacturer.
1 Safety
114494 - v.05 - 06022018 7
Caution
Ensure that the boiler is regularly serviced. Con
tact a qualified installer or arrange a maintenance
contract for the servicing of the boiler.
Caution
Only genuine spare parts may be used.
Important
Regularly check for the presence of water and
pressure in the heating installation.
1.2
Recommendations
Danger
This appliance can be used by children aged
eight and above and people with a physical, sen
sory or mental disability, or with a lack of experi
ence and knowledge, provided they are super
vised and instructed in how to use the appliance
in a safe manner and understand the associated
dangers. Children must not be allowed to play
with the appliance. Cleaning and user mainte
nance should not be carried out by children with
out adult supervision.
Warning
Installation and maintenance of the boiler must be
carried out by a qualified installer in accordance
with local and national regulations.
Warning
The installation and maintenance of the boiler
must be undertaken by a qualified installer in ac
cordance with the information in the supplied
manual, doing otherwise may result in dangerous
situations and/or bodily injury.
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
8 114494 - v.05 - 06022018
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 Description of the product
4.1 General description
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
Gas/air regulation
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.
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.
