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
T dealer
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 T in 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.
T declines 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

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
Never clean or service the boiler without first 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.

Description of the appliance
The
ACQUAHOME 25 B - 25 BS
boiler produces hot water for central heating and also produces domestic hot water in an integrated 60 litre storage cylinder. It can function at low temperature and is oil fuelled. The single stage oil burner has a vertical steel combustion chamber. Model
ACQUAHOME 25 BS
(unlike model
ACQUAHOME 25 B
) has a sealed chamber. The boiler body is thoroughly and effectively insulated with a layer of high density glass wool. The
ACQUAHOME 25 B - 25 BS
boiler's control logic incorporates
a total shutdown function to minimise energy consumption:
- In "Summer" mode ("Summer/Winter" selector turned to Summer position), the burner only starts up to restore the setpoint temperature of the water in the storage cylinder. In "Winter" mode ("Summer/Winter" selector turned to Winter position), the burner starts up either in response to a request for heat from the 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 25 B - 25 BS
boilers incorporate the following
safety and control devices:
-
A manual reset safety thermostat
that forces a safe­ty shutdown if boiler temperature exceeds the safety threshold (100°C). The sensor used to monitor this tem­perature 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.
