INSTRUCTIONS PERTAINING TO THE USER
This natural draught boiler is intended to be connected only to a flue shared between multiple dwellings in existing buil-
dings that evacuates the residues of combustion to the outside of the room containing the boiler. It draws the combustion
air directly from the room and incorporates a draught diverter. Due to lower efficiency, any other use of this boiler shall be
avoided and would result in higher energy consumption and higher operating costs.
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) checking the boiler has a fix external flue pipe which diameter has not to be less than the draught diverter’s collar
dimension.
c) make sure that the flue terminal draft is appropriate and that the terminal is not obstructed.
d) 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.
1.3.
The materials used for the domestic hot water circuit of the product comply with Directive 98/83/EC.
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
.
1. INSTRUCTIONS PRIOR TO INSTALLATION
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.
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.
The instructions shall state the substance of the following:
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concer-
ning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
