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 ope-
rations are accomplished:
a) accurate purging of the whole pipework in order to remove any deposits.
b) 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.
c) 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.
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.
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 settin-
gs.
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.
