96.091.1 - GB InstRUCtIOns FOR FIttERs
This boiler has been designed to heat water to a temperature lower than boiling point at atmospheric pressure.
It must be connected to a central heating system and to a domestic hot water supply system according to its performance and power
output.
Do the following before connecting the boiler:
a) Make sure that the boiler is adjusted to use the type of gas delivered by the gas supply. To do this, check the markings on the packaging
and the rating plate on the appliance.
b) Make sure that the flue terminal draft is appropriate, that the terminal is not obstructed and that no exhaust gases from other appliances
are expelled through the same flue duct, unless the latter has been specially designed to collect exhaust gas from more than one
appliance, in compliance with current laws and regulations.
c) Make sure that, if the boiler is connected to existing flue ducts, these have been thoroughly cleaned as residual products of combustion
may detach from the walls during operation and obstruct the flow of fumes.
d) To ensure correct operation and maintain the warranty, observe the following precautions:
1. DHW circuit:
1.1. If the water is harder than 20 °F (1 °F = 10 mg calcium carbonate per litre of water), install a polyphosphate dispenser or an
equivalent treatment system, compliant with current regulations.
1.. thoroughly flush the system after installation of the appliance and before use.
. Heating circuit
.1. new system
Before proceeding with installation of the boiler, the system must be cleaned and flushed to eliminate residual thread-cutting
swarf, solder and any solvents, using suitable proprietary products. To avoid damaging metal, plastic and rubber parts, only use
neutral cleaners, i.e. non-acid and non alkaline. Recommended cleaning products are:
SENTINEL X300 or X400 and FERNOX Regenerator for heating circuits. Use these products in strict compliance with the
manufacturers’ instructions.
.. existing system:
Before installing the boiler, drain the system and clean it to remove sludge and contaminants, using suitable proprietary products
as described in section 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 Protector for heating circuits. Use these products in strict compliance with the manufacturers’
instructions.
Remember that the presence of foreign bodies in the heating system can adversely affect boiler operation (e.g. overheating and
excessive noise of the heat exchanger).
Failure to observe the above will render the guarantee null and void.
The following notes and instructions are addressed to fitters to allow them to carry out trouble-free installation. Instructions for lighting
and using the boiler are contained in the ‘Instructions for Users’ section.
The Italian regulations governing installation, servicing and running of domestic gas-fired systems are contained in the following
documents:
• UNI-CIG 7129-7131 and CEI 64-8 standards
Additionally, bear in mind the following:
• This boiler can be connected to any type of double- or single-pipe convector plate, radiator or thermoconvector. Design the system
sections as usual, though, bearing in mind the available flow-head at the plate, as shown in chapter 22.
Do not leave any packaging (plastic bags, polystyrene, etc.) within reach of children, as it is a potential source of danger.
• Initial lighting of the boiler must be carried out by an authorised Service Engineer, as indicated on the attached sheet.
Failure to observe the above will render the guarantee null and void.
