CONNECTING THE BOILER TO THE ELECTRICITY MAINS NOT FOR ATTACK P BOILERS
Boilers are plugged into the electrical socket of 230 V/50 Hz placed near the boiler, with a supply
cable ended with a plug. In line with the ČSN EN 60 335-1, the plug must be approachable after the
boiler is installed. The socket must be adequately protected by zeroising or grounding and it must be
connected in line with the ČSN 33 21 80. The boiler and other parts of installation must be grounded.
Installation of the socket, room thermostat, circulation pump and service of electrical boiler parts can
be carried out only by a person with proper electrotechnical qualification, by the law No. 718/2002.

ELECTRICAL EQUIPMENT OF BOILERS

All the electroinstallation is placed on an insulating pad of the electrical board. On the front cover
there is a main switch, output switch (PLQ, KLQ), switch of failure unblocking (E, EZ), control button
of the boiler thermostat and thermomanometer. When the power supply fails, all the euipment
supplied with the power of 230 V is out of operation which means that a valve closes gas flow to
the burners. The flame of ignition burner (EKO, PLQ, P) is still burns and the boiler stays in a stand-
by mode. After the power supply starts again, the function starts automatically. Electrical installa-
tion is ready to connect the additional room thermostat, pump and switch contacts of three-way
valve. The room thermostat or the contacts of the three-way valve are connected after removing
the jumper on terminals 7, 8 and the circulation pump is connected to the terminals 3, 4, 5. By the
E boiler type is the room thermostat connected to the terminals 8, 9 and circulation pump to the
terminals 11, 12, 13. By the EZ boiler type is the room thermostat connected to the terminals 6, 7,
three-way valve to the terminals 3, 4, 5 and circulation pump to the terminals 12, 13, 14. Connection
of the room thermostat, circulation pump and three-way valve can be performed only by a person
with electrical qualification by the law No. 718/2002.
START  PUTTING THE BOILER INTO OPERATION
1. Remove the door.
2. Plug the flex cable into the electricity mains, the main switch is in the off position.
3. Open the gas supply to the boiler by a manual valve on the inlet pipe.
4. Set the required temperature of outlet water by knob of the thermostat.
5. The temperature is increased by turning the switch to the right (clockwise) and decreased by
turning the switch to the left (anticlockwise).
6. Press the control button of the gas combined electrical valve and hold it for 20 seconds. At the
same time press the button of piezo ignitor hardly for few times. Check the ignition burner
through the hole. ATTENTION – around the check hole there is a risk of burn when touch. Be
careful by work with the valve and piezo ignitor, not to get burned. Release the button of the
valve. The gas flows into the ignition burner and the sensor of thermo-couple is heated by flame.
If the flame is extinguishes, the process of ignition must be repeated (EKO, PLQ, P). By the KLQ,
KLV and EZ versions, are the burners ignited automatically after switching the main switch and
setting up the boiler thermostat.
