ase the temperature, or counterclockwise to decrease it.

Setting the temperature
1.5 Faults
Once the adjustments described above have been made,
the heater is ready to operate automatically. When a hot
water tap is opened, an intermittent discharge is genera-
ted on the ignition electrode to light the burner.
All electronic models have an ionization electrode built
into the burner to monitor flame presence. If a malfun
-
ction or lack of gas causes the heater to turn off, close
the hot water tap.
It is then necessary to eliminate the fault or obstacle pre-
venting the gas from reaching the heater, e.g., inadver-
tent closing of the gas cock, empty gas cylinder, etc.
To reactivate the heater, close and open the hot water
tap.
If no hot water is produced after eliminating the cause
and opening the hot water tap, repeat the process.
If the problem persists, call the technical support center.

2 INSTALLATION MANUAL
2.1 General information
The heater may only be instal-
led by an authorized technician,
in accordance with all instruc-
tions contained in this manual,
standard UNE 26, and local in-
stallation and exhaust regula-
tions.
2.2 Location
Make sure the water heater chosen is the most suitable:
•
To adequately meet the system’s hot water require-
ments.
•
For the gas to be used (see water heater dataplate).
•
For the water supply pressure, necessary for operation
(see table of characteristics).
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 combu
-
stion air will compromise normal operation and the
evacuation of fumes. Also, the fumes forming under
these conditions are extremely harmful to health if
