The system is started by switching the ON/OFF
switch ON (pos. 1 in Fig. 4.1.1). After the start
phase, pressing the manual key (pos. 13 in Fig.
4.1.1) for longer (approx. 5 s) and by selecting
the required manual temperature at the rotary
selector (pos. 6 in Fig. 4.1.1), “Manual mode”
can be adjusted (see also Fig. 3.6.1). Before
the final commissioning, test the high limit
safety cut-out function and fine-tune the gas
burner by measuring the flue gas (see chapter
5.1 “Gas burner”).

Testing the high limit safety cut-out
function
Caution:
Risk of burning!
The boiler body will get very hot.
Never touch metallic parts on
the burner or the boiler body.
Before starting the test, close the ball valve at
the heating flow connection and isolate the
servomotor of the three-way diverter valve. For
this, press the reset button on the servomotor
of the valve (pos. 5.2 in Fig. 3.5.1) and turn the
motor a quarter of a revolution anti-clockwise.
Briefly press the manual key (pos. 13 in Fig.
4.1.1) to test the high limit safety cut-out. The
hold down the rotary selector (pos. 6 in Fig.
4.1.1) until the high limit safety cut-out has
responded. The display (pos. 14 in Fig. 4.1)
display “STB test” (see Fig. 3.6.2). After a
successful test, reset the high litres capacity
manually after the boiler has cooled down
(open the ball valve at the heating flow
connection again) by pressing the manual key
briefly again when the display shows “RESET”.
Note:
Check all connections for
leaks before commissioning the
system. To prevent corrosion
products and sedimentation, observe the
rules of VDI 2035 [or local regulations].
Take measures to stabilise or reduce the
water hardness if the fill and top-up water
is particularly hard. We recommend the
use of Fernox anti-scaling and anti-
corrosion agent KSK (part no. 15 60 50) in
accordance with the manufacturer’s
instructions for areas suffering from
extreme water hardness.
Important:
During the system
operation, regularly check the
water pressure at the pressure
gauge (green range) and top-up, if
required.
3.6 Initial start-up
The ROTEX GasSolarUnit/GasCompactUnit is
read for operation after all connections have
been made; it can then be commissioned by
your heating contractor. Carefully check the
attached checklist prior to commissioning.
When all questions in this checklist were able
to be answered with “Yes”, then the factory-
set burner can be started temporarily.
Note:
Immediately after starting the
system, check the burner adjust-
ment with a smoke gas analyser
and adjust the burner, if required
(see chapter 5.1).
