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 thatthesmoke
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:
– 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 fitting approved chimneys, please observe the
manufacturer’s specifications.
* 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 final installation location of the Heating Unit.
Assembly
Level and height
– Level the boiler base and adjust its height by
turningthelevellingstuds(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 flue
outlet (16) Fig. 5.
– If a top flue outlet is required (17) Fig. 5, undo
the screw, remove the top casing panel and
its insulation and fit it onto the rear flue 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 flue
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 flue gas removal) See Fig. 2.
Should additional elbows or extensions be
needed, they will have to be ordered
additionally (see flue accessories catalogue
for room-sealed wallhung boilers).
Watertighttest
– Fill the system with water (in Heating Units
GTI and GTA, through the fill 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.
ElectricalConnections
For connecting additional and/or external
appliances, please refer to the instructions
supplied with the CCE Control Panel.
Operation
Procedure prior to first 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 fill 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 flash twice
before showing the temperature scale from
40 °C to 140 °C, with the segment in line with
114 °C flashing 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
“flame” LED will go off.
– Next press “–” key and “radiator”
simultaneously. The screen will flash and
then display code 00 only.
– Stop pressing “–” and “radiator”.
– Next press “+” and “–” simultaneously.
The screen will flash twice before
displaying the pressure scale with the fill
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
