Starting the boiler up
Important:
Putting the boiler into operati-
on and starting it up for the first time must
be done by an authorised service only!
If you wish to start the boiler after it has
been put into operation, make sure that:
1. the boiler is connected to power supply;
2. the gas valve underneath the boiler is
open;
3. the HeW pressure is within the recom-
mended range 1 – 2 bar.
Turn the main switch (Fig. 1) to position (I).
The display will light up.
In the event of a safety boiler shutdown
during a flame-out, emergency thermostat
or flue gas thermostat (applies to KOZ boi-
ler) intervention, the “lightning” LED on the
control panel will flash or light up. In case
of a flame-out the boiler can be unblocked
using the main switch by switching it to po-
sition (0) and after a while back to position
(I). If the emergency shutdown recurs af-
ter a short time again, or if the boiler can-
not be RESET, call an authorised service
organisation.
If the emergency shutdown was triggered
by the emergency thermostat interven-
tion, the boiler cannot be unblocked by
the main switch (RESET). Unblocking the
emergency thermostat must be done by
an authorised service technician, and this
operation cannot be regarded as a war-
ranty repair.
Important:
The boiler must not be run
with the emergency or flue gas thermostat
disabled or replaced with a device other
than the one specified by the manufactu-
rer.
Turning the boiler off
Turn the main switch (Fig. 1) to position
(0).
If the boiler is to remain shut down for a
protracted period of time, turn off the gas
valve upstream the boiler. When shutting
the boiler down, take into consideration
the ambient temperature in the given sea-
son. If the boiler and system is not protec-
ted by an anti-freeze agent (Alycol Termo),
the boiler and system may be damaged. If
there is a danger that the boiler may free-
ze, drain all the HoW pipes.
Starting the boiler up and turning it off
Boiler control
Using the boiler without room
control unit
When run in this mode, the boiler main-
tains the set HeW temperature. No room
control unit is connected, the terminals
for its connection must be interconnected
with a jumper (standard factory setting).
Setting procedure:
• turn the main switch to position (I);
• set the HeW temperature to the required
value on the control panel.
Using the boiler with room control
unit
The boiler maintains the set HeW tempe-
rature. The room control unit connection
terminal jumper must be removed and the
room control unit wired to the terminals.
The boiler is turned on and off to maintain
the set temperature in the room in which
the control unit is installed. Radiators in
this room must not be equipped with ther-
mostatic valves.
Important:
You must set on the boiler
control panel a HeW temperature (tempe-
