evaluation cable for the burner must be connected additionally to the bottom sensor plug. Details about<br />
this can be found in the connection box manual.<br />
The cables for the ventilator, the electronic fuse and the conveyor screw will have been fitted into the<br />
<strong>boiler</strong>. The cables for the components which need to be fitted by client, such as those for mains connection<br />
or for the <strong>boiler</strong> circulation pump, must be fitted into the <strong>boiler</strong> by a qualified electrician. For this purpose,<br />
there is a little channel for the cables on the left side of the <strong>boiler</strong>. The cable for the ventilator will have<br />
already been fitted through this channel.<br />
Now insert all plugs into their appropriate places on the control panel.<br />
The control panel should then be pushed into place until it is safely secured on its little pins.<br />
1.13 Electric Heating Cartridge<br />
If requested, the KUENZEL <strong>boiler</strong> can be equipped with an electric heating cartridge (article no. 150246)<br />
for frost protection. For the connection of this electric heating cartridge, a connection for strong currents<br />
(3x 400 volts 16 amps) should be inserted.<br />
The electric heating cartridge can also be operated with 230volt 25 amps. For this, the wiring of the<br />
cartridge should be changed according to the details of the manufacturer. Caution: These tasks must<br />
only be carried out by a qualified electrician. Please consult the enclosed electric heating cartridge<br />
instructions manual if you want to find out the exact wiring plan.<br />
On the back of the <strong>boiler</strong>, there is a two inches socket, into which the electric heating cartridge can be<br />
inserted.<br />
The electric heating cartridge has its own thermostats. This thermostat can be adjusted to a variable<br />
temperature between 5oC and 75oC. If the electric heating cartridge only has the function of a frost<br />
guard, it is sufficient to adjust the thermostats by turning the control to the left (5o C).<br />
In order to avoid switching on the electric heating cartridge unintentionally, the contact for the secondary<br />
heating can also be used. The electric heating cartridge cannot be, however, switched on or off directly<br />
by using this. An in–between relay is always required. Important: This also applies to the connection<br />
with 230 volts!<br />
