Compactness
ECO3: the ultimate in space saving!
BAXI introduced in its product range ECO3, a gas
wall hung boiler distinguished by the compact
dimensions: the real innovation lies in the
maximum space saving ensured considering the
boiler installed.
A particular flue system has been specially
designed to enable ECO3to perfectly fit into any
modern house where usually space represents an
issue: ECO3can be even installed in a cupboard.

LCD display
ECO3is provided with a full information LCD
display: a wide section where you can easily
check all the main data related to the boiler
working.
Functions and anomalies are displayed not only
by codes but in particular by immediate symbols.
This makes the information clear and prompt!

Reliability and easiness of use
ECO3is the result of the great combination of high reliable
components and a meticulous choice of all the materials used.
To make an example, the gas and combustion groups have
already been tested in three years of production (more than
100.000 boilers manufactured), and the hydraulic group is the
evolution of the existing group present in other models of WHB
range.
Besides, ECO3has been designed with a particular care of the
components positioning to ensure an easy access for the
maintenance.

If a fault occurs, the display reads out an error message identifying
it (es. E 10):
To RESET the gas boiler, turn selector (Figure 2) to “R” for at least 2 seconds. If the fault
persists, call an authorised service centre.
Note: It is possible to carry out n° 5 relighting attempts in a row, after which the RESET function
is disabled and the gas boiler still blocked.
To carry out a new RESET attempt, turn the selector (figure 2) in OFF position for at least 2
seconds.
