1.2Technical safety equipment
1.2.1 Gas control valve
The water heater has been fitted with a gas control block consisting of a
This gas control block is suitable for gasses from the first, second and third gas family. The maximum inlet pressure is 50 mbar.
1.2.2 Flue down draught safety device
The appliance is fitted with a flue down draught safety device. The operation of the safeguard is based on the principle of the Thermal Reflux Safeguard (T.R.S.).
The appliance has been fitted with a T.R.S., see Figure 2.
This T.R.S. can be recognized by the brass colored helix coil which is connected to the lower edge of the draught diverter. The helix coil has been connected to the thermostat by means of a capillary tube. The wiring of the thermostat has to be connected to the couple circuit before the heater is put into operation.
It is the aim of the T.R.S. to prevent flue gasses from the water heater entering the room where the water heater has been placed, instead of passing through the flue to outside atmosphere. The
After the cause of the reentry of flue gasses has been traced the device can be put back into operation again. In case
of T.R.S. the RESET button has to be pressed first.
If this failure occurs frequently, this indicates that the flue suffers from down draught conditions. We advice that necessary remedial actions be carried out by a competent person.
Important
The T.R.S. should never be put out of operation. Reentry of flue gasses to the building could be harmful and cause poisoning or death.
