Instructions pertaining to the user
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.
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
Initial lighting of the boiler must be carried out by a licensed technician. Ensure the following ope-
rations 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.
To correctly light the burner proceed as follows:
1) provide power supply to the boiler;
2) open the gas cock;
3) follow the directions given below regarding the adjustments to be made at the boiler control pa-
