COMMISSIONING INSTRUCTIONS

Checks to be made at first lighting and after all maintenance operations that involved disconnection from the systems or an oper-
ation on safety devices or parts of the boiler:
Before lighting the boiler

Open any valves between the boiler and the system.

Check the tightness of the gas system, proceeding with caution and using an approved leak detection fluid or portable gas
detector to detect any leaks.

Check correct prefilling charge of the expansion vessel. (0.2bar below cold fill pressure)

Fill the water system and make sure all air contained in the boiler and the system has been vented, by opening the air vent
valve on the boiler and any vent valves on the system.

Fill the condensate trap and check correct connection of the condensate system.

Make sure there are no water leaks on the system, DHW circuits, connections or the boiler.

Check correct connection of the electrical system and efficiency of the earth connection.

Make sure the gas pressure value for heating is that required.

Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler

Checks during operation


Switch on the unit.

Make sure the fuel circuit and water systems are tight with no leaks.

Check the integrity of the flue and air ducts while the boiler is working. Record the flue pressure @ standby, min and max
outputs.

Check the correct tightness and functionality of the condensate drain system and trap.

Ensure the water is circulating correctly between the boiler and the system.

Ensure the gas valve modulates correctly in heating and domestic hot water modes.

Put the boiler through several ignition sequences to ensure correct firing operation.

Using a combustion analyser connected to the boiler flue outlet, check that the CO
operating at max. and min. output, corresponds to that given in the technical data table for the corresponding type of gas.
(See section on gas valve adjustment)

Make sure the fuel consumption indicated on the meter matches that given in the technical data table on page 5

Check the correct programming of the parameters and carry out any necessary customization (compensation curve, pow-
er, temperatures, etc.).

Periodical inspection

To ensure correct operation of the unit, it is necessary to have an annual inspection carried out by qualified personnel.

Check and clean heat exchanger with suitable products if dirty or clogged

Check and clean burner (do not use chemical products or wire brushes)

Check and clean electrodes, which must be free of deposits and correctly positioned

Check seals and gaskets (burner, sealed chamber, etc.)

Check and clean sludge filters and system filters

Check, clean and fill condensate drain traps

Check wiring, contacts, electrical actuators

Check and clean generator air inlets and boiler room air intakes

Check and clean fume evacuation duct-manifold-flue system.

Check expansion tank and prefilling pressure

Check for correct and stable system water pressure, ensuring conformity with the required working pressure.
