1. 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 accom-
plished:
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 de-
signed 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.
d) to ensure correct operation of the appliance and avoid invalidating the guarantee, 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.
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 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 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.

2. InstruCtIons prIor to CommIssIonIng

Initial lighting of the boiler must be carried out by a licensed technician. Ensure the following operations are
carried out:
a) compliance of boiler parameters with (electricity, water, gas) supply systems settings.
b) compliance of installation with the laws and regulations in force.
c) appropriate connection to the power supply and grounding of the appliance.
The names of authorized Service Centres are listed on the accompanying sheet.
Failure to observe the above will render the guarantee null and void.
Prior to commissioning remove the protective plastic coating from the unit. Do not use any tools or abrasive
detergents as you may spoil the painted surfaces.
