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. 49, fig. 50 is fig. 51) in conformity with the current stan-
dards, 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.

BEFORE CARRYING OUT ANY OPERATION THAT REQUIRES REMOVING
B
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!
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 earth the system.
The boiler is prewired and provided with a three-pole cable, without a plug, for con-
nection to the electric line. The connections to the grid must be made with a perma-
nent connection and equipped with a bipolar switch whose contacts have a minimum
opening of at least 3 mm, interposing fuses of max. 3A between 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.
The unit's supply 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, only use cable "HAR H05
VV-F" 3x0.75 mm2 with max. external diameter of 8 mm.
Room thermostat (optional)
CAUTION: The room thermostat must have clean contacts. CONNECTING 230 V.

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.
