above, the two screws that fasten the top casing
panel and this panel should be removed
beforehand.
- The left-hand casing panel incorporates a cable
entry and a cable tie for securing the wiring
coming from the various devices external to the
boiler.
Top and Front Casing Panels
- For boilers which are delivered disassembled:
- Support the top cover on the side profiles, slightly
slide it over them until the three control panel
locating lugs engage the front slots in the cover
plate; then secure it through the rear with the
two self-tapping screws.
- Fit the front cover (37) so that the limit stops
(38) at the bottom of the side panels engage in
the slots of the cover and rest it on the lower
hooks (39) so that they coincide with the notches
in the cover. It can be fastened to the sides
through the top by means of the snap-on locks
provided for this purpose.

Storage cylinder casing (GTA version only)
- Suspend the front cover from the boiler
supporting base (11).
- Bolt together the rear half-covers and hang them
from the boiler supporting base.
- Fit the side panels (with the bevel at the front)
introducing in its slots the locating lugs in the
front cover and rear half-covers and fasten them
to the vertical brackets (8) using the black screws
and washers provided.

- Rest the top covers. The front top one against
the front panel and the rear panel so that the
folded rim covers the rim on the rear half-covers.
Operation
Operations prior to the first lighting
- Check that the installation is full of water and
move the fixed pointer on the combined temp./
altitude gauge to the position which corresponds
to the system static head.
- Bleed the air in the system and radiators.
- In installations with a sealed expansion vessel,
top up with water, if necessary, until the
adjustable pointer on the combined temp./
altitude gauge is slightly above the fixed one.
With an open expansion vessel, top up until the
adjustable pointer levels with the fixed one.
- Bleed the gas train by loosening the pressure
test point screw on the gas valve.
- With GTA version boilers also ensure that the
cold water inlet cock on the Flexbrane safety
unit is open; likewise, open a tap to bleed the
DHW circuit.
- Open the boiler gas service cock.

operate correctly.
7 - Bleed the air in the system and ensure that
the radiators reach the correct working
temperature.
With GTA version boilers, also:
8 - Move the service selector switch (13) to the
position marked
and check whether the
DWH pump is running*.
9 - Set the control thermostat knob
(5) to
between 30°C and 55°C.
10 - Bleed the air in the DHW circuit and ensure
that it reaches the preset temperature.
Note:
Should the pilot flame accidentally snuff out, wait
one minute before lighting up again.
Stop:
- With G100/20 to 50 and G100/20 to 40 GTA
boilers for use with natural/propane gas, turn (15)
in the direction of the arrow. With G100/20-30,
G100/20-30 GTA boilers for use with town gas
and G100/70 to 110 boilers for natural/propane
gas, press (17).
- Turn ON the On/off switch (3). With G100/40 to
110 and G100/40 GTA boilers for use with town
gas, close the gas inlet cock, otherwise the pilot
flame will remain alight.
- Turn OFF the On/off switch (3) in order to isolate
all power supply to the boiler, while keeping the
pilot flame alight.
