1 USER'S MANUAL
1.1 Introduction
The new CPA is a high-performance, low-
emission heater for domestic hot water
production, powered by natural gas or LPG
and equipped with a compact, WATER-
COOLED, battery-powered burner with
electronic ignition, designed for indoor
installation.

1.3 Turning the heater on and off
When the unitis working,
the temperature near the
peephole may be high.
Avoid contact as there
may be risk of burns.
Preliminary checks and operations
1 Make sure the hot water taps are
closed.
2Open the gas supply cock to the heater,
located at the gas connection to the unit.
3Check that the 1.5 V batteries are properly
installed with the correct polarity (+/-). To
replace the batteries, see (3.4 Replacing
the batteries).
4Alsoverify that the batteries are
sufficiently charged for heater
operation.
1.3.1 Turning the unit on
Turn the knob to the required water heating
level. The unit will begin operating every time
hot water is drawn.
fig. 2 - Turning the unit on
1.3.2 Turning the unit off
The burner goes off automatically when hot
water is no longer demanded.

cod. 3541S050 - Rev. 01 - 07/20195
EN
CPA
To use the unit again, no action is required.
To completely shut off the unit, place the knob
in the () position.
fig. 3 - Turning the unit off
If the water heater will not be used for an
extended period of time, close the gas cock
supplying the unit.
If the unit will be inactive
for an extended period of
time during the winter, all
water should be
removed to avoid ice
damage.
1.4 Settings
1.4.1 Setting the burner power manually
Use the knob (3 fig. 1) to
selectthe heater power.
You may choose between the
minimum, maximum, and intermediate
positions, depending on the required heating
power.
If the knob is turned counterclockwise, the
unit will operate at maximum power. If the
temperature is too high, for example in the
summer, or if you need a reduced flow
of not very hot water,turn
the knob clockwise. This
reduces the power, and therefore the
gas consumption.
In the ●position, the unit
is turned off.
1.4.2 Setting the temperature
Turn the water temperature selector
clockwise to increase the temperature, or
counterclockwise to decrease it.
fig. 4 - 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
generated 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 malfunction 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 preventing the gas from reaching the
heater, e.g., inadvertent 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
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 characteristics).

cod. 3541S050 - Rev. 01 - 07/20197
EN
CPA
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.
Otherwise there may be risk of suffocation
and intoxication or explosions and fire..
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.
