WARNING
GENERAL WARNINGS
The instructions manual forms an integral part of the product and therefore must be carefully re-
tained and always kept with the unit; if lost or damaged, a copy of these may be downloaded from
the manufacturers web site www.Biasi.co.uk.
Installation of the unit and any other service or maintenance operation must be carried
out by a Gas Safe registered installer.
The unit must be used for the purpose envisaged by the manufacturer. No contractual and
extra-contractual responsibility can be taken for damage caused to people, animals or things,
as a result of installation, regulation and maintenance errors or improper use.
The safety or automatic regulation devices of the unit must not be modified.
This unit is used to produce hot water, it must therefore be connected to a domestic hot
water distribution network compatible with its performance and power.
In the event of a water leak, turn off the water supply and promptly notify your Gas Safe reg-
istered installer.
If away for a long time, turn off the gas supply. If there is the risk of freezing, empty the water
heater of the water it contains.
In the event of a fault and/or poor operation of the unit, turn it off, refraining from any at-
tempt to repair it or any direct intervention.
Maintenance of the unit must be carried out at least once a year: this may be undertaken by
any Gas Safe registered engineer.
BASIC SAFETY RULES
The use of the unit requires strict observance of some basic safety rules.
Do not use the device for purposes other than those for which it is designed.
It is absolutely prohibited to obstruct the flue terminal grills and the ventilation opening of
the room in which the unit is installed, with rags, papers or anything else.
If a smell of gas is detected, do NOT activate electric switches, the telephone and any other
object that might cause a spark. Air the room by throwing doors and windows wide open and
turn off the gas at the mains. Contact the national gas emergency helpline on 0800 111999.
Do not rest objects on the unit.
Do not leave containers and flammable substances in the room where the unit is installed.
Any attempt at repair is prohibited in the event of a fault and/or poor operation of the unit.
Use of the unit by children or inexperienced people is prohibited.
Tampering with the sealed elements is prohibited.

DESCRIPTION OF UNIT
1 FEATURES AND BENEFITS
Micro-computer intelligent control system
The core component of the gas water heater
is a micro computer intelligent control system,
which is one of today’s most advanced mecha-
tronic technology. The CPU chipset can ana-
lyze automatically and set the optimal working
parameter rapidly according to different data
such as the flowing water quantity, the pres-
sure situation and the actual inlet water tem-
perature.
Digital control for automatic constant tem-
perature of outlet water
This function is to monitor the outlet water
temperature by a temperature sensor and to
transfer the information to the micro-comput-
er, so that the micro-computer can adjust the
gas and air supply quantity to guarantee the
constant outlet water temperature according
to the temperature set by the user and the ac-
tual inlet water temperature automatically.
Pressure
The lowest start-up water pressure of this
product could reach 0.02 MPa (0.2 bar) (or a
minimum flow rate of 2.5 L/min), so it could
also be used in the residence area with low
pressure.
"AI" Artificial Intelligent Memory Function
The water heater remembers the last set point
temperature removing a need to re set every
time the unit is activated.
Energy saving
This product has advanced technologies
called Strengthened Combustion and Forced
Combustion.
These features aim to make the best use of
heat energy with high working efficiency.
Set temperature by touch
You can set the required temperature easily by
touching the digital display. The temperature
range is from 35°C to 65°C.
Multiple safety protection
This product has built in safety protection, this
includes self-check protection, flame-out pro-
tection, over-heat protection, accidental pow-
er-cut protection, fan breakdown protection,
electric overload protection, electric leakage
protection, high wind pressure protection and
over temperature protection.
Tips
The above conclusion comes from the safety
protection test under lab conditions.
It may be affected by the surroundings in its
actual place of installation. Thus, please use
the product in proper conditions.
