2 INSTALLATION MANUAL

2.1 General information

The heater may only be installed by an authorized technician, in
accordance with all instructions contained in this manual, standard
UNE 26, and local installation and exhaust regulations.
2.2 Location
• Make sure the water heater chosen is the most suitable:
To adequately meet the system's hot water requirements.
For the gas to be used (see water heater dataplate).
For the water supply pressure, necessary for operation (see table of characte-
ristics).
• Make sure the room where the unit is installed meets all the requirements of the
Current Regulations. In particular, this unit is an "open chamber" type and must
only be installed and operate in permanently ventilated places. An insufficient
supply of combustion air will compromise normal operation and the evacuation
of fumes. Also, the fumes forming under these conditions are extremely harmful
to health if dispersed in the domestic environment.
BE RISK OF SUFFOCATION AND INTOXICATION OR EXPLOSIONS AND
Therefore the place of installation must be free of dust, flammable materials or
objects or corrosive gases.
• Position the water heater as close as possible to the hot water taps, near the sink, but
NEVER above a cooktop. It must also be situated as close as possible to the flue or the
start of the flue gas exhaust pipe.
If the unit is installed inside a cabinet or joined laterally to other elements,
space must be allowed for removing the casing and performing normal
maintenance activities.
