The following remarks and instructions are addressed to Service Engineers to help them carry out a faultless installation. In-
structions regarding lighting and operation of the boiler are contained in the 'Instructions pertaining to the user' section.
Note that installation, maintenance and operation of the domestic gas appliances must be performed ex­clusively by quali-
fied 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, as
shown in section 24.
* 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.

12. 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 to a domestic hot water supply system in compliance with its performances
and output power.
Have the boiler installed by a Qualified Service Engineer and ensure the following operations are accomplished:
a) careful checking 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) careful checking that the flue terminal draft is appropriate; that the terminal is not obstructed and that no other appliance
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 laws and regulations in force.
c) careful checking 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 come off during operation of the boiler and obstruct the flue duct.
To ensure correct operation of the appliance and avoid invalidating the guarantee, observe the following precautions:
1.
hot water circuit:
1.1. 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.
1.2. Domestic Hot Water circuit must be thoroughly flushed after the installation of the appliance and before its use.
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.
To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non alkaline. The
recommended products for cleaning are:
SENTINEL X300 or X400 and FERNOX heating circuit restore. To use this product proceeding strictly in accordance
with the maker's directions.
2.2. existing system
Before proceeding with installation of the boiler, the system must be cleaned and flushed out to remove sludge
and contaminants, using suitable proprietary products as described in 2.1.
To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non-alkaline such
as SENTINEL X100 and FERNOX heating circuit protective. To use this product proceeding strictly in accordance
with the maker's directions.
Remember that the presence of foreign matter in the heating system can adversely affect the operation of the
boiler (e.g. overheating and noisy operation of the heat ex­changer).
Failure to observe the above will render the guarantee null and void.
