GENERAL INFORMATION
General Safety Information
b Check that the product is complete, undamaged
and as ordered as soon as you receive it. Report any
discrepancies or damage to the Tdealer
who sold it.
b This product must be installed by a legally qualified
heating engineer. On completion of the installation,
the installer must issue the owner with a declaration
of conformity confirming that the installation has been
completed to the highest standards in compliance
with the instructions provided by Tin this
instruction manual, and that it conforms to all applicable
laws and standards.
b This product must only be used for the purpose for which
it is designed and made, as specified by T.
Tdeclines all responsibility, contractual or
other, for damage to property or injury to persons or
animals caused by improper installation, adjustment,
maintenance or use.
b The room where the boiler is installed must be properly
ventilated to ensure a sufficient supply of air for correct
combustion.
b If you notice any water leaks, disconnect the boiler from
the mains electricity supply and shut off the water supply.
b The boiler must be serviced at least once a year.
b Periodically check that pressure in the central heating
circuit, when cold, is approximately 1.5 bar and below
the maximum limit specified for the boiler.
b If the boiler is not going to be used for an extended
period of time, perform the operations described later in
this manual.
b This manual is an integral part of the equipment and
therefore must be stored carefully and must ALWAYS
accompany the boiler even if it is sold to another Owner
or User or transferred to another plant. If it is damaged
or lost, request another copy from your local Technical
Assistance Centre T.
Precautions
The operation of any appliance that uses fuel, electrical power
and water demands that a number of fundamental safety
precautions be respected:
a Do not allow children or infirm persons to operate the
system unsupervised.
a It is forbidden to use electrical devices or equipment,
such as switches, appliances, etc. if there is a smell of
gas or un-burnt products. If so:
- Ventilate the room, opening doors and windows
- Close the fuel shut-off cock.
a Do not touch the boiler while barefoot or wet.
a Neverclean orservice theboiler withoutfirst disconnecting
it from the mains electricity supply by turning the mains
power switch and the control panel switch OFF.
a Do not tamper with or adjust the safety or control devices
without prior authorisation and instructions from the
manufacturer.
a Never pull, disconnect, or twist the electrical cables
coming from the appliance even if it is disconnected
from the mains electricity supply.
a Do not obstruct or restrict the vents in the room where
the boiler is installed. Adequate ventilation is essential for
correct combustion.
a Do not expose the boiler to the elements. It is not
designed for use outdoors.
a It is prohibited to leave inflammable substances and
containers in the room where the boiler is installed.
a Do not dispose of packaging material into the
environment, or leave it within the reach of children, since
it can become a potential hazard. Dispose of packaging
material in compliance with applicable legislation.
a It is forbidden to operate the boiler without water.

5ENGLISH
Description of the appliance
The ACQUAHOME 32 B - 32 BS boiler produces hot water for
central heating and also produces domestic hot water in an
integrated 110 litre storage cylinder.
It can function at low temperature and is oil fuelled.
The single stage oil burner has a horizontal steel combustion
chamber.
Model ACQUAHOME 32 BS (unlike model ACQUAHOME 32 B )
has a sealed chamber.
The boiler body is thoroughly and effectively insulated with a
layer of high density glass wool.
The ACQUAHOME 32 B - 32 BS boiler's control logic incorporates
a total shutdown function to minimise energy consumption:
- With the mode key set to "Summer", the burner only
starts up to restore the setpoint temperature of the
water in the storage cylinder;
- With the mode key set to "Winter", the burner starts up
in response to a heat request from the central heating
system (i.e. when the room thermostat switches the
heating on) or to restore the setpoint temperature of the
water in the storage cylinder (DHW heat requests are
prioritised over central heating requests).
Safety devices
ACQUAHOME 32 B - 32 BS boilers incorporate the following
safety and control devices:
- A manual reset safety thermostat that forces a safe-
ty shutdown if boiler temperature exceeds the safety
threshold (100°C). The sensor used to monitor this tem-
perature is located on the body of the heat exchanger;
- Sensors that measure the temperature of the boiler and
storage cylinder;
-
An electronic burner controller that monitors the correct
functioning of the selected burner program and sends
a lockout signal to the control panel in the event of an
error.
b The intervention of a safety device indicates a potentially
dangerous malfunction in the system. Contact the
manufacturer’s Technical Assistance Centre immediately.
b Safety devices must only be replaced by the
manufacturer's Technical Assistance Centre using
original spare parts. Refer to the spare parts catalogue
supplied with the boiler.
a Do not use the boiler if any of its safety devices are faulty.
Always check that the boiler is functioning correctly after
repairs have been made.
