1 Safety
1.1 Recommendations
Danger
This appliance must not be used by people (and children) with a
physical, sensory or mental disability, or by people with a lack of
technical experience, unless they are supervised by someone who
can assure their safety, or they have been instructed in the correct
use of the appliance. Do not allow children to play with the appli
ance.
Warning
Installation and maintenance of the boiler must be carried out by a
qualified installer in accordance with local and national regula
tions.
Warning
Only qualified persons are authorised to assemble, install and
maintain the installation.
Warning
Removal and disposal of the boiler must be carried out by a quali
fied 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 prevent hazardous situations from arising.
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 maintenance and servicing
work.
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 in
stall a main bipolar switch with an opening gap of at least 3 mm
(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 opera
tion.
The boiler protection only protects the boiler, not the system.
Check the water pressure in the system regularly. 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).
Note
Keep this document near to the boiler.
Note
Casing panels may only be removed for maintenance and servic
ing purposes. Refit all panels when maintenance work and servic
ing are complete.

Note
Instruction and warning labels must never be removed or covered
and must be clearly legible throughout the entire service life of the
boiler. Replace damaged or illegible instruction and warning labels
immediately.
Note
Modifications to the boiler require the written approval of Remeha.

4.1 Gas settings
4.1.1 Adaptation to a different gas type
Warning
Only a qualified installer may carry out the following operations.

Start speed 17 17 17 17
Restrictor ø (mm) 8,4 8,4 – –
Before operating with a different type of gas, carry out the following steps.
1. Check the correct diameter of the existing restrictor (see table) and
replace it if necessary.
2. Set the fan speed as indicated in the table for the relevant gas type.
The speed can be changed with a parameter setting.

3. Check the setting of the gas/air ratio.
4.1.2 Checking/setting the combustion
1. Unscrew the cap from the flue gas measuring point.
2. Insert the probe for the flue gas analyser into the measurement
opening.
Warning
During measurement, seal the opening around the sensor fully.
Note
The flue gas analyser must have a minimum accuracy of
±0.25% O2/CO2.
The flue gas analyser must meet the requirements of BS 7927
or BS-EN 503793 and be calibrated according to the manufac
turer's requirements.
3. Measure the percentage of O2/CO2 in the flue gases. Take meas
urements at full load and at part load.
Checking/setting values O2/CO2 at full load
1. Set the boiler to full load.
2. Measure the percentage of O2/CO2 in the flue gases.
3. Compare the measured value with the checking values in the table.

rect the gas/air ratio.
Note
The 210-80 and 210-120 boilers are equipped with a restrictor on
the gas valve unit. They can therefore only be set to part load.
5. Using the adjusting screw, set the percentage of O2/CO2 for the gas
type being used to the nominal value. This should always be inside
the highest and lowest setting limit. The direction in which the ad
justment screw must be turned to increase or decrease the gas flow
is indicated on the gas valve unit.
6. Check the flame through the inspection window.
Note
The flame must not blow off.
Checking/setting values for O2/CO2 at part load
1. Set the boiler to part load.
2. Measure the percentage of O2/CO2 in the flue gases.
3. Compare the measured value with the checking values in the table.

6.1 Removal/recycling
Note
Removal and disposal of the boiler must be carried out by a quali
fied person in accordance with local and national regulations.
To remove the boiler, proceed as follows:
1. Switch off the boiler's electrical connection.
2. Shut off the gas supply.
3. Shut off the water supply.
4. Drain the installation.
5. Remove the siphon.
6. Remove the air supply/flue gas outlet pipes.
7. Disconnect all pipes on the boiler.
8. Remove the boiler.

7.2 Optional electrical connections
7.2.1 Connection options for the PCB (SCU-X03)
The SCU-X03 PCB can control a modulating central heating pump. De
pending on the make and type of pump, the pump can be controlled by a
0–10 V, 4–20 mA or a PWM signal. The speed of the pump is modulated
based on the signal received from the boiler.
Note
For correct connection of the pump, see the documentation sup
plied with the pump.
Connecting on/off contact
1. Connect the on/off contact of the CH pump to the connector X1.
Caution
Do not use the on/off contact to interrupt the power supply to the
pump.
Connecting a central heating pump
1. Connect the CH pump controller to the connector X2.
Select the type of signal that will be received from the boiler using the rota
ry knob SW1 on the PCB. See table below

Caution
If possible, use the pump modulation signal. This provides the
most accurate pump control.
In positions 3 to 9 the control PCB receives no signal from the
boiler and the boiler responds as in position 0.
If the automatic burner unit does not support pump modulation,
the pump will behave as an on/off pump.
Select the type of signal that controls the pump using the rotary knob SW2
on the PCB. See table below.
