When installing a Dik Geurts fire with H
Installation without the supplied safeguards is not permitted.
Caution!
A Dik Geurts fire is always supplied with the following safeguards:
• Safety heat exchanger (heat exchanger with incorporated cooling coil);
• Thermal safety valve, with fluid filled detector and capillary tube;
• Pressure relief valve, 3 bar
Check that these safeguards, which are necessary for the installation, are present and only then start performing
Caution!
the installation!
• Commissioning the fire without the certainty that all safety components have been installed optimally, is
prohibited.
• Make sure there is a good provision for the aeration of the supplied heat exchanger.
• After installation, all safety components should be easily accessible for inspection and service.
• All components used for the installation at the water side should be resistant to a temperature of at least 110
°C.
• installed components that are not part of Dik Geurts' scope of delivery, must be demonstrably suitable for
application in central heating systems.
• When the fire is used for the first time, all steps of the operating manual must be observed.
• The user must be clearly instructed about the operation and maintenance of the installation.
• Recommend the user to make annual appointments for inspection and maintenance.
• The electrical connection must be achieved in accordance with the locally applicable standard.
If the installation does not comply with these points, any form of product warranty will become invalid.
Caution!

3.4.1 Thermal safety valve

In accordance with standard EN 12828, the appliance is protected against a water temperature that is too high.
For this purpose, a thermal safety valve is supplied.
The capillary tube of the thermal safety valve should never be kinked, shortened or damaged in any way.
Caution!
The safety valve is made with a very thin and fragile capillary tube. Its function is to transfer the pressure that is
Caution!
being accumulated in the detector to the valve. If the valve leaks due to damage, the operation is no longer
guaranteed and the valve should be replaced.
The thermal safety valve must be mounted on a 'cool' location (< 50 °C) and must always be easily accessible.
Caution!
A water pressure between 1.5 and 2.0 bar must be guaranteed.
Caution!
If the water pressure is not guaranteed, installation should only take place on an open expansion system.
Caution!
The exit of the overflow pipe should be mounted in such a way, that no hazard can occur for the user. When this
Caution!
safeguard is activated, water at approximately 100 °C will flow out of the discharge pipe. The connection of a
thermal safety valve is displayed in a diagram (see appendix 2 fig. 2).
Make sure the exit of the discharge pipe of the thermal safety valve can be checked for flow-through and leakage.
Caution!
This connection pipe for the thermal safety valve must be installed in a location where no frost can occur. Freezing
Caution!
must be prevented at all times.
