1. Switch the boiler off.

2. Open the windows.

3. Report any leaks immediately.

4. Evacuate the property.

5. Contact a qualified installer.

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.

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.
