9.4 ANTI CALCER SYSTEM
This system provides an indirect control against calcer formation. The water
temperature in the heating circuit of the plate exchanger cannot exceed 70
degrees, regardless of the flow rate and temperature. By this way, occurrence
of calcer is prevented.
9.5 PREVENTION AGAINST FROST
When the temperature in the heating system drops down to 5°C, inside the
boiler there is a security system that automatically switches on the burner.
When the water temprature reaches 45°C, burners are switched off. In order for
this system to work and protect your device against freezing, the electrical
connection of the device, the gas valve and the installation valves must be in
open position. This system is active when the device is off.
9.6
When a sensor failure occurs in hot water system, E06/E12 warning code
appears on LCD screen. Call authorized service.
9.7
When a sensor failure occurs in heating system, E05 warning code appears
on the LCD screen. Call authorized service.
9.8
When there is an over pressure in the heating system, there is an available
security ventile to dispose the water.
9.9
If there are thermostatic valves on each radiator, even when all
thermostatic valves are switched off, there is an automatic by pass system in
order to provide the passage of minimum water flow.

GAS PRESSURE SETTING
The gas pressure settings given in the following table should be adjusted while
changing gas type of the device.
IMPORTANT NOTE:
This modification operation can only done by an
authorised service.
Diameter of the injectors must be suitable for fuel type used.
Natural Gas Injector diameter: 1.35mm
LPG/Propan Injector diameter: 0,75mm
Attention:
Be sure about the resealing of the parts that were unsealed while
gas modification operation. Test to see if there is gas leakage after the
operation.
