In installations with flexible pipe for LPG
(approved, do not confuse with flexible
elastomer connection), pay special at-
tention to the following:
• The pipe must comply with applicable regulations.
• Avoid areas with heat emissions.
• Prevent the pipe from bending or being pinched shut.
• The connections on both sides (gas valve and other compo-
nents) must comply with the regulations of the country where
the water heater is installed.
2�6 Electrical connections
The unit's electrical safety must be ensured
with grounding, as established by safety
standards. Have qualified personnel check
the effectiveness of the grounding system,
as the manufacturer will not be liable for
any damage caused by a lack of grounding
on the installation.
The unit's power cable may not be replaced by the user. If the ca-
ble is damaged, turn off the unit and call the authorized technical
support center to have it replaced.
To replace it use only HAR H05 VV-F cable, 3 x 0.75 mm
maximum outer diameter of 8 mm.
2�7 Air and flue gas ducts
This is a type C unit, with a sealed chamber and forced
draft. The air inlet and flue gas outlet must be connected
to systems such as those indicated below.
The unit is approved for operation with all configurations of the
Cxy flue shown on the technical data card (some of these are
shown as an example below).
It is however possible that some configurations are limited or pro-
hibited by law, standards or local regulations.
Before installing, check and strictly comply with the requirements
in question.
Also comply with the provisions for hanging on walls and/or ceil-
ings and the minimum distances to windows, cables, ventilation
openings, etc. Section 2.2
