8. GENERAL INFORMATION

The following remarks and instructions are addressed to Service Engineers to help them carry out a faultless installation. Instructions regarding lighting and operation of the boiler are contained in the ‘Instructions per- taining to the user’ section.

Note that installation, maintenance and operation of the gas appliances must be performed exclusively by qualified personnel in compliance with current standards.

Please note the following:

*This boiler can be connected to any type of double- or single feeding pipe convector plates, radiators, thermoconvectors. Design the system sections as usual though taking into account the available output / pump head performances.

*Do not leave any packaging components (plastic bags, polystyrene, etc.) within children’s reach as they are a potential source of danger.

*Initial lighting of the boiler must be effected by a Qualified Service Engineer.

Failure to observe the above will render the warranty null and void.

9. INSTRUCTIONS PRIOR TO INSTALLATION

This boiler is designed to heat water at a lower than boiling temperature at atmospheric pressure. The boiler must be connected to a central heating system and, on models with this option, to a domestic hot water supply system in compliance with its performances and output criteria.

IMPORTANT! The gas boiler is supplied without the following components which must be provided exclusively by qualified personnel:

•Expansion vessel;

•Pressure relief valve;

•Circulating pump;

•Boiler filling tap.

Before connecting the boiler ensure the following operations have been completed:

a) Check that the boiler is fit for operation with the type of gas available. For more details see the notice on the packaging and the label on the appliance itself.

b)Check that the flue terminal draft is appropriate; that the terminal is not obstructed and that no other applian- ce exhaust gases are expelled through the same flue duct, unless the flue is especially designed to collect the exhaust gas coming from more than one appliance, in conformity with the standards and regulations in force.

c)Check that, in case the flue has been connected to pre-existing flue ducts, thorough cleaning has been carried out in that residual combustion products may be created during operation of the boiler and obstruct the flue duct.

To ensure correct operation of the appliance and avoid invalidating the warranty, observe the following precautions:

1.Hot water circuit:

If the water hardness is greater than 20 °F (1 °F = 10 mg calcium carbonate per litre of water) a polyphosphate or comparable treatment system responding to current regulations must be used.

2.Heating circuit

2.1.New system

Before proceeding with installation of the boiler, the system must be cleaned and flushed out thoroughly to eliminate residual thread-cutting swarf, solder and solvents if any, using suitable proprietary products.
