System water characteristics

In the presence of water harder than 25° Fr (1°F = 10ppm CaCO

3

), use suitably treated

water in order to avoid possible scaling in the water heater.

3.4 Gas connection

The gas must be connected to the respective union (see figure on cover) in conformity
with the current regulations, with a rigid metal pipe or with a continuous flexible s/steel
tube, installing a gas cock between the system and water heater . Make sure all the gas
connections 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! THERE IS A DANGER OF ELECTRIC
SHOCK WITH THE RISK OF INJURY OR DEATH!

B

The unit must be connected to an efficient grounding system in accordance with
current safety regulations. Have the efficiency and suitability of the grounding
system checked by professionally qualified personnel; the Manufacturer de-
clines any liability for damage caused by failure to ground the system.
The water heater is prewired and has a "Y" type cable (without plug) for con-
nection to the electric line. The connections to the grid must be made with a per-
manent connection and equipped with a double-pole switch with contact gap of
at least 3 mm, interposing fuses of max. 3A between the water heater 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 ca-

ble gets damaged, turn the unit off and have the cable replaced only by
professionally qualified personnel.

 In case of replacement, only use cable

“HAR H05 VV-F”

 3x0.75 mm2 with max. external diameter of 8 mm.

3.6 Fume ducts

B

THE BOILER MUST BE INSTALLED IN PLACES THAT MEET THE FUNDA-
