Installation
– Observe current regulations.
– In the event of being installed in the kitchen,
embedded in the furniture under the countertop,
it should be desinged in a way, that there is
enough room for access for the maintenance
and cleaning operations of the boiler, and on
top of that, ensure that the smoke exhaust
pipes, the water connections and the chimney
are easily reachable.
– With all the GAVINA Confort models, except
GT-F, GTI-F and GTA-F Confort, please note
that in order to obtain the data plate output the
chimney size should conform to the minimum
height and diameter there on indicated:
M i n i m
C i h m n y e h e g i t h
5 m
6 m
≥
7 m
– In the GAVINA GT-F, GTA-F and GTI-F Confort
boiler, the air suction pipe and the smoke
exhaust pipe are separated. In both cases, their
maximum length will be of 7 m (straight line)
plus an elbow of 90°; this length will be reduced
in 0,7 m. for each added elbow.
– Every metre reduced in length of the air suction
pipe allows an increase of 0,5 m in the length
of the exhaust pipe.
Example:
Air suction pipe length = 1 m.
(maximum allowed is 7 m.)
Reduction = 7 m – 1 m = 6 m
Maximum exhaust pipe length = 7 m + (6 x
0,5) = 10 m.

– The installation should include a switch, a circuit
breaker or other omnipolar disconnect switch
to isolate all power supply lines to the unit.
Notes:
* When fi tting approved chimneys, please observe the
manufacturer's specifi cations.
* To remove possible residue from the chimney, it is
advisable to have a handhole at the base for this
purpose.
* Ensure there is a 230V-50 Hz single-phase earthed
power point as well as a water supply and a drain near
the fi nal installation location of the Heating Unit.
Assembly
Level and height
– Level the boiler base and adjust its height by
turning the levelling studs (12) (Fig. 1) provided.
To raise the boiler, turn the studs clokwise. To
lower it, turn the studs anticlockwise.
Connecting the boiler to the system
– Remove the top casing panel.
– Make the connections for the Flow and Return
circuit through (b) and (a), as well as the mains
water inlet and Domestic Hot Water outlet (in
GTI and GTA models) through (c) and (d).
See Fig. 3.
– Route the draw-off cock and the safety valve
discharge to the general waste system.
Conection to the chimney
All models, except GAVINA GT-F, GTI-F and
26 GTA-F Confort.
– The Heating Units are delivered with rear fl ue
outlet (16) Fig. 5.
– If a top fl ue outlet is required (17) Fig. 5, undo
the screw, remove the top casing panel and its
insulation and fi t it onto the rear fl ue socket.
– Pack round the joint between the boiler and
the chimney in order to prevent ingress of
unwanter air.
GAVINA GT-F, GTA-F and GTI-F
Confort
– Connection of the air supply tubes and the fl ue
outlet sections should be on a horizontal plane.
Two straight sections of about 1 m and 80 mm
diameter are supplied (one for air supply and
another for fl ue gas removal) See Fig. 2. Should
u m d a i m t e r e r o
additional elbows or extensions be needed,
s q u a e r s d i e
they will have to be ordered additionally (see
1 7 5 , c m
fl ue accessories catalogue for room-sealed

Watertight test
– Fill the system with water (in Heating Units GTI
and GTA, through the fi ll point cock (4) Fig. 1,
until the point in which the pressure in the bar
scale in the control panel is located between
1 and 1,5 bar.
– Check that there are no leaks in the hydraulic
circuit.
Fuel supply
– Make the connecttion between the burner and
the fuel supply line.
Electrical Connections
For connecting additional and/or external
appliances, please refer to the instructions
supplied with the CCE Control Panel.
Operation
Procedure prior to fi rst lighting
– Connect the boiler to the power supply and
check that the control panel is under voltage.
The LED of "power on" (13) symbol lights up in
green. (Fig. 4)
– In case of malfunction, please refer to the "Fault
Codes" section in the Instructions for the CCE
control panels.
– Bleed the air from the installation and radiators
and top up if necessary, until the fi ll pressure
value on the scale reaches the required level.
– Careful attention should be paid to the general
instructions supplied with the CCE control
panels.
– Check that the boiler parameters and those for
the installation and associated features such
as temperature, service selection, day, time,
etc. have been properly selected and set in
accordance with the Instructions for the CCE
control panels.
Checking operation of the safety
limit thermostat
It is advisable to carry out this check in order to
prevent future serious malfunction. This can only
be done if no lockout condition exists, that is,
under code 00 (refer to the "Fault Codes" section
in the Instructions for the Control Panels) or
because of a lockout (code 11) caused by the
limit thermostat itself.
– With the service selector key (14) select "wait".
(Fig. 4)
– Press the "bar" key. The pressure scale and its
current value will be displayed.
– Next press "+" and "–" simultaneously. The
screen will flash 5 times before displaying
code 00 only - if no lockout condition exists. In
case of lockout, the code corresponding to the
fault that caused it will be displayed in the way
explained in the Instructions for the mentioned
CCE control panels.
– Stop pressing "+" and "–".
– Press the "+" key, and without releasing it, press
"radiator". The screen will fl ash twice before
showing the temperature scale from 40 °C to
140 °C, with the segment in line with 114 °C
fl ashing slowly. The burner will run but the pump
will not if the boiler temperature is equal to or
lower than 80 °C. The boiler sensor operation
is cancelled.
1 – If the limit thermostat comes into operation
before the boiler reaches 114 °C, it means
that it is working correctly. In this case, the
burner will not run but the pump will.
– The screen will alternate displaying code
04 and the 40 °C to 140 °C scale. No
Service indication will be displayed (15) in
the top screen.
– Wait until the boiler temperature drops to
80 °C and reset the limit thermostat. The
"fl ame" LED will go off.
– Next press "–" key and "radiator"
simultaneously. The screen will fl ash and
then display code 00 only.
– Stop pressing "–" and "radiator".
– Next press "+" and "–" simultaneously.
The screen will fl ash twice before displaying
the pressure scale with the fi ll value. The top
screen (15) will show "wait".
– Stop pressing "+" and "–".
2 – If the limit thermostat does not come into
operation before the boiler reaches 114 °C,
it means that it is not working correctly. In
this case, the burner will not run but the
pump will.
