3.4 Gas connection

The gas must be connected to the relevant connection (see fig. 24) in conformity with the
current standards, using a rigid metal pipe or a continuous surface flexible s/steel tube
and installing a gas cock between the system and boiler. Make sure all the gas connec-
tions are tight.

3.5 Electrical connections

IMPORTANT

B
BEFORE CARRYING OUT ANY OPERATION THAT REQUIRES REMOVING
THE CASING, DISCONNECT THE BOILER FROM THE ELECTRIC MAINS
WITH THE MAIN SWITCH.
NEVER TOUCH THE ELECTRICAL COMPONENTS OR CONTACTS WITH
THE MAIN SWITCH TURNED ON! DANGER OF ELECTRIC SHOCK WITH
RISK OF INJURY OR DEATH!
B
The unit must be connected to an efficient grounding system in accordance with
applicable safety regulations. Have the efficiency and suitability of the ground-
ing system checked by professionally qualified personnel; the Manufacturer de-
clines any liability for damage caused by failure to earth the system.
The boiler is prewired and provided with a three-pole cable, without a plug, for
connection to the electric line. The connections to the grid must be made with
a permanent connection and equipped with a bipolar switch whose contacts
have a minimum opening of at least 3 mm, interposing fuses of max. 3A be-
tween the boiler and the line. Make sure to respect the polarities (LINE: brown
wire / NEUTRAL: blue wire / GROUND: yellow-green wire) in the connections
to the electric line.
B
The unit's supply cable MUST NOT BE REPLACED BY THE USER. If the cable
gets damaged, turn the unit off and have the cable replaced only by pro-
fessionally qualified personnel. In case of replacement, only use cable
"HAR H05 VV-F" 3x0.75 mm2 with max. external diameter of 8 mm.
Room thermostat (optional)
B
IMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTAGE-FREE
CONTACTS. CONNECTING 230 V TO THE ROOM THERMOSTAT TERMI-
NALS WILL PERMANENTLY DAMAGE THE ELECTRONIC BOARD.
When connecting time controls or a timer, do not take the power supply for
these devices from their breaking contacts Their power supply must be by
means of direct connection from the mains or with batteries, depending on the
kind of device.
Accessing the electrical terminal block
The electrical terminal block can be accessed after removing the casing. The arrange-
ment of the terminals for the various connections is also given in the wiring diagram in
fig. 28.

3.6 Fume ducts

Important
The unit is a "C type" with sealed chamber and forced draught, the air inlet and fume out-
let must be connected to one of the following extraction/suction systems. The unit is ap-
proved for operation with all the Cny flue configurations given on the dataplate. Some
configurations may be expressly limited or not permitted by law, standards or local reg-
ulations. Before installation, check and carefully follow the instructions. Also, comply with
the instructions on the positioning of wall and/or roof terminals and the minimum distanc-
es from windows, walls, ventilation openings, etc.

Baffles
Boiler operation requires fitting the baffles supplied with the unit, according to the follow-
ing tables.
To replace the baffle (ref. 1 - fig. 11), proceed as indicated in fig. 11.

For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to fig. 25. Any horizontal sections of the fume exhaust must
be kept sloping slightly towards the boiler, to prevent possible condensate from flowing
back towards the outside and causing dripping.
