General information
1.1 - SYMBOLS USED IN THE MANUAL
Pay special attention when reading this manual to the parts marked by the symbols:
NOTE!
Suggestions for the user
ATTENTION!
Possible hazardous situation
for the product and the environment
DANGER!
Serious danger for
personal safety and life
1.2 - APPROPRIATE USE OF APPLIANCE
The STILE 27 appliance has been built according to the current level of engineering and acknowledged
technical safety rules.
Nonetheless, if improperly used, dangers could arise for the safety and the very life of the user and other
persons or damage to the equipment or other objects.
The appliance is intended to operate in hot air circulation heating systems. Any other use must be
considered improper.
UNICAL shall not be held liable for any damage resulting from improper use; in this case the user is fully
responsible for the risk.
Use according to the intended purposes also includes careful compliance with the instructions in this
manual.
1.3 - WATER TREATMENT (see specific booklet)
•The hardness of the feed water conditions the frequency at which the domestic hot water exchanger must be
cleaned.
•If the water has a hardness greater than 15°f, we recommend using water softeners, chosen according to the
characteristics of the water.
•We recommend checking and cleaning the eventual domestic hot water exchanger at the end of the first year
of use and every two years thereafter.
1.4 - INFORMATION FOR USER
•The user must be instructed concerning the use and operation of his heating system, in particular:
•Deliver these instructions to the user, as well as other documents concerning the appliance inserted in the
envelope contained in the packaging. The user must keep this documentation so that it is available
for further consultation.
•Inform the user about the importance of the air vents and the flue gas exhaust system, highlighting
their essential features and the absolute prohibition of modifying them.
•Inform the user concerning controlling the system’s water pressure as well as operations to restore it.
•Inform the user concerning correct temperature control, control units/thermostats and radiators for saving
energy.
•Remember that the system must receive regular maintenance once a year and a combustion analysis
must be performed in the timetable foreseen by standards in force.
•Should the appliance be sold or transferred to a new owner or if you move and
leave the appliance, always make sure that the instruction booklet accompanies it in order to be
consulted by the new owner and/or installer.

Installation and maintenance must be performed in compliance
with standards in force according to the instructions of the
manufacturer and by qualified and certified personnel in
compliance with law.
By professionally qualified personnel we mean: personnel
with specific technical skill in the field of heating system
components for civil use, domestic hot water production and
maintenance. Personnel must have the qualifications provided
for by current legislation.
Incorrect installation or improper maintenance can cause
damage to persons, animals or objects for which the
manufacturer is not responsible.
Before performing any cleaning or maintenance, disconnect
the appliance from the energy mains by acting on the switch
of the system or by unplugging it.
Do not obstruct the terminals of the intake/exhaust ducts.
In case of failure and/or malfunctioning of the appliance, switch
it off and do not try to repair it or intervene on it directly. Contact
only personnel qualified in compliance with law.
Any repairs must be performed solely by personnel
authorised by Unical using original spare parts only. Failure to
comply with the above can jeopardise the safety of the
appliance.
To guarantee appliance efficiency and its correct operation,
yearly maintenance must be performed by qualified
personnel.
Should you decide not to use the appliance, parts entailing
potential sources of hazard must be made safe.
Should the appliance be sold or transferred to a new owner or
if you move and leave the appliance, always make sure that
the instruction booklet accompanies it in order to be consulted
by the new owner and/or installer.
Only original accessories must be used for all appliances with
optionals or kits (including electric).
This appliance is intended solely for the use for which it was
expressly designed. Any other use is to be considered
improper and therefore dangerous.
