following tests:
- Control and safety elements (gas valve, flow sensor, thermostats, etc.) must work correctly
- Circuit of flue gas exhaust must be perfectly tight
- Closed chamber has to be tight
- Pipes and ending air-flue gas must have no barriers, nor leakage
- System for condense water outlet must be functional, without barriers and it cannot leak
- Burner and exchanger must be clean and without sediments. By eventuall cleaning, do not use
chemical means, nor steel brushes.
- Electrode must be placed correctly, with no sediments
- Gas and water supply connections must be ensured against leakage
- Pressure of water in distribution device in cold state must be approximately 1 bar. If pressure is
different, adjust this value.
- Circulation pump must not be blocked
- Expanse vessel must be filled
- Flow and gas pressure must correspond to data given in appropriate tables
Cover, control panel and external parts of boiler can be cleaned by soft wet cloth, eventually soak in water
