competent company. The pipe pressure of the connected cold water has to be at least 2
bar and may not exceed 4.5 bar. Ensure a minimum passage of 20 l/min. A water filter
needs to be installed in front of the valve intake in accordance with EN 13443. The sensing
element of the thermal safety valve may need to be installed with an extension (1/2” x 40
mm [
Connection no. 3 on illustration 1 or illustration 2
]).
Please have the performance reliability of the safety heat exchange tested annually by an
authorised and competent company.
2.5.1 Testing the safety heat exchange
Test the safety heat exchange by temporarily overheating the burner to a boiler
temperature >97°C.
Where this is not possible, conduct the following alternative check:
1. Remove the thermostat of the thermal safety valve sensing element from the burner
2. Dip the thermostat in a container with water
3. Bring the water in the container to the boil by heating
4. The valve should now allow the inlet of cold water into the coil in the boiler
Risk of injury due to hot water.
If this check fails (the thermal safety valve does not open or does not close
sufficiently later), The sensing element must be exchanged. Attention! It is not
permissible to conduct any manipulation of the thermal safety valve and the safety
heat exchange coil.
We recommend having a service check conducted by a competent company prior to the
heating season. Where the burner is used only temporarily and where unfavourable winds
or climatic conditions are present, greater care during initial operation is essential. After a
prolonged period without firing up the burner, a check of the openness of the flueways is
necessary. During operation the surfaces of the burner are very hot; therefore please use
protective gloves when handling the device.
Supervise small children when they are present in the room where the burner is installed.
Only original replacement parts and accessories may be used for the burner.
2.6 Commissioning
The appliance and chimney installation should be tested by a competent person before
final handover to the user or client to ensure that it is safe, fit for use and capable of
providing the expected performance and service, in accordance with the method stated
below.
The tests and checks given in 2.6.1, 2.6.2 and 2.6.3 should be carried out before the
appliance is lit for the first time.
