6 STARTING UP THE BOILER
6.1 Prior warnings
Repair and maintenance of the boiler must be carried out by a qualified professional, authorised by
DOMUSA TEKNIK . For optimum functioning and conservation of the boiler, it should be serviced
annually.
Carefully read this instruction manual and keep it in a safe, easily-accessible place. DOMUSA
TEKNIK will not be liable for any damages caused by failure to follow these instructions.
During some of the operating phases, a forced noise may be heard for a few minutes. This is normal
and does not affect the boiler's integrity in any way.
Before any servicing, disconnect the boiler from the mains .
6.2 Filling the installation
The hydraulic installation must include a fill valve, a manometer, a safety valve, drain valves and the
necessary hydraulic components for correctly filling the installation.
To fill the installation, open the fill valve until the installation manometer shows a pressure of 1 - 1.5
bars. The installation must be filled slowly, bleeding the air from the water circuit using the drain
valves provided for this purpose. Close the fill valve after filling.
IMPORTANT: Switching on the boiler with no water inside could result in serious damage.

The following steps are obligatory in the start-up sequence:
- Remove the cleaning brush and the rake supplied with the boiler.
- Check the flue is correctly installed using the condensation inspection plate and a draught
stabiliser
- Check the external hydraulic anti-condensation kit is correctly installed.
- Check that the temperature relief valve is properly installed.
- If the installation has flow and return valves, check they are open.
