Starting up the heat generator
The product has a gas-adaptive heat cell that automatically
adjusts to the relevant gas type. We recommend that you
start up the heat cell using the following steps. Calibration
establishes the operational readiness. This calibration is
also a prerequisite for the correct measurement of gas flow
pressure and CO₂ content.
–
Deleting existing calibration values
–
Calibrating in maximum mode
–
Calibrating in minimum mode
▶
Install the front casing.
▶
Ensure that there is sufficient hot water circulation.
▶
Navigate to Menu → Installer level → Check programs
and confirm by pressing
▶
Start check programme P.04.
◁
Existing calibration points are deleted. The display
shows the successful deletion.
▶
Start check programme P.01.
–
Duration: 7-10 minutes. Automatic programme end
after 15 minutes
◁
If the circulation in the heating system is sufficient,
the test routine starts and determines the calibration
points for maximum power. S.93 is displayed.
▽
S.85 is displayed. The circulation in the heating sys-
tem is not sufficient.
◁
After max. 10 minutes, S.04 is displayed.
▶
Press
to end the check programme.
▶
Start check programme P.02.
–
Duration: 3-5 minutes. Automatic programme end
after 15 minutes
◁
If the circulation in the heating system is sufficient,
the test routine starts and determines the calibration
points for minimum power. S.93 is displayed.
▽
S.85 is displayed. The circulation in the heating sys-
tem is not sufficient.
◁
After max. five minutes, S.04 is displayed.
▶
Press
to end the check programme.
◁
All calibration points have been determined.

3.
Use a screwdriver to undo the sealing screw of the
measuring nipple (1) at the gas valve.
4.
Connect a pressure gauge (2) to the measuring nipple
(1).
5.
Open the gas isolator cock.
6.
Start up the product with the check programme P.01.
▽
If S.85 is shown, the hot water circulation must be
extended.
◁
S.93 is briefly displayed.
◁
If the display switches to S.04, the product is ready
for the measurement.
7.
Measure the gas flow pressure in comparison with the
atmospheric pressure.
–
Permissible gas flow pressure for operation
with G20 natural gas: 1.8 ... 2.5 kPa (18.0
... 25.0 mbar)
–
Permissible gas flow pressure for operation
with G25 natural gas: 1.8 ... 2.5 kPa (18.0
... 25.0 mbar)
–
Permissible gas flow pressure for operation
with G31 liquid gas: 4.25 ... 5.75 kPa (42.50
... 57.50 mbar)
8.
Decommission the product.
9.
Close the gas isolator cock.
10. Remove the pressure gauge.
11. Tighten the screw on the measuring nipple (1).
12. Open the gas isolator cock.
13. Check the measuring nipple for gas tightness.
Conditions: Gas flow pressure not in the permissible range
Caution.
Risk of material damage and operating
faults caused by incorrect gas flow pres-
sure.
If the gas flow pressure lies outside the per-
missible range, this can cause operating
faults in and damage to the product.
▶
Do not make any adjustments to the
product.
▶
Do not start up the product.
