Water Filling Valve
10. COMMISSIONING, USE AND TURNING OFF THE BOILER
10.1. Commissioning, Filling Water into Boiler and Heater Installation
- First of all, the electrical connection of the boiler is done. The electrical connection of the device
must be connected to a grounded power supply line that can supply enough voltage (230 VAC, 50 Hz)
for the device.
- All radiator valves should be opened.
- CH flow and CH return of boiler should be opened. Check them.
- After all these processes, filling valve is slowly opened and filling procedure is initiated. The filling
process continues until the water pressure of 1.5-2 bar is seen on the LCD display and then the filling
valve is closed.
- When the water pressure increase to 0.8 bar, the LCD will show "AP" and the boiler will switch to
automatic air vent mode. In this case you should definitely wait for 160 seconds without pressing
"RESET".
- Check water pressure on pressure indicator frequently and ensure that the pressure is between 1.5
and 2 bar when system is cold. If the pressure drops frequently, it means that there is a water leak in
the system. In such case, it is necessary to call a plumber.

ATTENTION : Always close the water filling valve, the installation water may leak and
damage the environment.
- To discharge air out of CH installation, purgers of the radiator is loosened and air is discharged until
water comes out of radiators. This procedure is done for all radiators.
- Pressure is checked again on LCD screen. The filling valve is opened and again pressure is raised to
1.5 – 2 bar level. Radiator purgers are checked again to see if there is any air left inside of heating
installation. For full efficient heating, all air must be discharged.
- Finally, check for any leaks in the radiator and piping.
- Check the domestic water installation by opening the hot water tap. Check for any leaks in the
piping.
- The exhaust gas flue assembly must be installed from the original parts in accordance with the
instructions.
- Gas supply must be checked by the qualified gas company.
- Must be called authorized service to start up the boiler after all these processes are completed.
- Commissioning must be strictly performed by authorized service.
- At the end of the commissioning of the device after installation, please ask for information of
authorized service on operating the device and relevant safety devices on device.
ATTENTION: In order to prevent calcification of the heat exchanger, you are advised not
to use well water, natural spring water instead of mains water.
