2.4 Gas connection

Before carrying out the connection, make sure the unit is arranged for operation
B
with the type of fuel available and carefully clean all the pipes of the gas system to
remove any residues that could affect proper boiler operation.
The gas must be connected to the relevant connection (see fig. 79 ) in conformity with the current standards, with a rigid
metal pipe or with a continuous surface flexible s/steel tube, installing a gas cock between the system and boiler. Make
sure all the gas connections are tight. The gas meter capacity must be suitable for the simultaneous use of all the units
connected to it. The diameter of the gas pipe leaving the boiler does not determine the diameter of the pipe between
the unit and the meter; it must be chosen according to its length and pressure losses, in conformity with the current
standards.
Do not use the gas pipes to earth electrical appliances.
B
In case of connection in cascade, make sure to install a fuel shutoff valve externally
with respect to the modules.

ATTENTION
BEFORE CARRYING OUT ANY OPERATION REQUIRING REMOVAL OF THE
B
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!
The unit must be connected to an efficient grounding system in accordance with
B
applicable safety regulations. Have the efficiency and suitability of the grounding
system checked by professionally qualified personnel; the Manufacturer declines
any liability for damage caused by failure to ground the system.
The boiler is pre-wired and equipped with a three-core connection cable to the
electric line without plug. The connections to the grid must be made with a perma-
nent connection and equipped with a bipolar switch with contact opening of at least
3 mm, interposing fuses of max. 3A between the boiler and line. Make sure to res-
pect the polarities (LINE: brown wire / NEUTRAL: blue wire / GROUND: yellow-
green wire) in the connections to the electric line.
The unit's power cable MUST NOT BE REPLACED BY THE USER. If the cable
B
gets damaged, turn the unit off and have the cable replaced only by profes-
sionally qualified personnel. In case of replacement, use exclusively "HAR H05
VV-F" 3x0.75 mm2 cable with maximum ext. diameter of 8 mm.
Room thermostat (optional)
CAUTION: The room thermostat must have clean contacts. CONNECTING 230 V.

TO THE TERMINALS OF THE ROOM THERMOSTAT WILL IRREPARABLY DA-
MAGE THE ELECTRONIC CARD.
When connecting a remote timer control or a timer switch, do not take the power
supply for these devices from their cut-out contacts. Their power supply must be
taken with a direct connection from the mains or with batteries, depending on the
kind of device.
