3.1 Key installation regulations
3.1.1 Location
•
It is not allowed to install instantaneous gas water heaters above a heat source (i.e. electric or gas cooker, etc.)
•
It is not allowed to install instantaneous gas water heaters in rooms exposed to temperatures below 0ºC. If there is such a
risk, it is necessary to drain the heater out of water.
•
It is not allowed to keep any solvents, paints, inflammable gas, glue, detergents or any other chemicals that may cause
corrosion.
Heater mentioned in this manual has a degree of electrical protection assured by the housing: IP 44 Equipped with a cord
and plug can be installed in Zone 2 or further - it should not be installed in Zone 1. Device can be installed in zone 1 only if it
is permanently connected to the power source.

3.1.2 Electric system
The heater was designed as a first-class device. It was designed for single-phase power supply with alternating current rated
voltage of 230 V / 50 Hz. The heater equipped with a cord and plug must be plugged to a wall socket with a safety pin. If you
connect the heater to a permanent power supply, electrical installation should be equipped with the heater disconnected from
the power source.
Note:
The control of the water heater must be connect to a power source. If L and N cables are improperly connected, the
control system is not able to detect a flame and it make an ignition trial until the water heater switches off in a safety
mode. You will see E1 error code on the LCD.
In such a case it s necessary to change L and N cobles in the socket. The water heater will switch on after it detects it
is properly connected.
3.1.3 Gas system
It is recommended to install a gas cut – off valve as close to a water heater as possible.
The water heater must be connected to gas mains with steel or copper pipes, accordingly to applicable regulations.
If you use liquefied gas, the water heater must be connected with a liquefied gas system, with a gas pressure reduction device
situated on a gas cylinder, by means a flexible tube no longer than 3m and pressure strength 300 kPa, which is resistant to
components of liquefied gas, mechanical damages and temperature 60°C.
Gas appliances with thermal output exceeding 10kW (i.e. heaters covered by this instruction as well), should be connected with
the mentioned above flexible tube by the means of steel pipe at least 0.5 m long.
The gas system must be equipped with a pressure reduction device that enable to reduce pressure to
p = 3,7 kPa.
