No. Procedure
6 Check the entire gas route for leaks
7 Carrying out a chimney draught meas-
urement
8 CO₂ measurement
9 If the CO₂ is not within the tolerance:
10 After setting the CO₂, activate chimney
sweep mode again and measure the
CO₂ content
11 CO measurement (target value <
80 ppm)
12 Check the condensate tray, condens-
ate siphon and condensate discharge
for leak-tightness
13 Switching off the product and switching
it back on again
14 Programme the heating controller with
the customer and check that the hot
water/heating are working correctly
15 Stick sticker 835593 "Read the oper-
ating instructions" on the front of the

Comment
Leak-detection spray or leak detector
(a leak detector is especially recom-
mended for checking the burner seals
for gas tightness)
If required, tighten the burner seal
(tightening torque: 12 Nm)
The maximum draught must not ex-
ceed 20 Pa. If the draught is too great,
the chimney draught must be restricted
using suitable measures.
Target value for nominal heat loading:
Only carry out the measurement after
five minutes of normal operation
– 9.3 vol.% ±0.2 with natural gas H
Target value for the minimum heat
load:
– 9.0 vol.% ±0.2 with natural gas H
Adjust the CO₂ and then take the
measurement again
Target value for nominal heat loading:
– 9.3 vol.% ±0.2 with natural gas H
Target value for the minimum heat
load:
– 9.0 vol.% ±0.2 with natural gas H
Carry out a visual check or also use a
CO measuring instrument to go along
the sealing points.
End the maximum output operation
Handing over the operating instructions
