Checking the balanced flue system soundness (annular gap
check)
For balanced flue systems tested together with the wall mounted gas fired boiler, some authorities waive the requirement for a soundness test (pressure test)
during commissioning by the flue gas inspector.
15
Initial start-up, inspection, maintenance
Further details regarding the individual steps (cont.)
We recommend that your heating engineer carries out a simple leak test during
the commissioning of your system. For this it would be sufficient to check the
CO 2 concentration in the combustion air at the annular gap of the balanced flue
pipe.
The flue pipe is deemed to be sound if
the CO 2 concentration in the combustion air is no higher than 0.2 % or the
O 2 concentration is at least 20.6 %.
If actual CO2 values are higher or O 2
values are lower, then pressure check
the flue pipe at a static pressure of
200 Pa.

Flue gas emissions test
The Vitodens 333 is set up in the factory for natural gas E and can, with the aid
of a conversion kit, be converted to natural gas LL or LPG P (only 26 kW).
During commissioning or maintenance, check the CO 2 level at the flue outlet.
Note
The MatriX burner of the Vitodens 333 is preset for the entire gas group. Therefore, the burner requires no further setting or adjustment.
Subject to the Wobbe index, the CO 2 content fluctuates between
& 6.6 to 10.0% for natural gas E
& 7.0 to 10.0% for natural gas LL
& 8.5 to 10.5% for LPG P (only 26 kW)
Compare the actual CO 2 value with the above CO 2 value ranges for the individual gas groups (check the gas group with your mains gas or LPG supplier).
If the actual CO 2 value deviates by more than 1% for natural gas or 0.5% for
LPG (only 26 kW), proceed as follows:
& Check that the correct gas restrictor has been installed.
& Check the balanced flue system for soundness, see page 16.
Maintain limits to EN 483 and EN 297 (CO content < 1000 ppm).
2. Open the gas shut-off valve, start
the boiler and create a heat
demand.
1. Connect a flue gas analyser at the
flue gas port A on the flue outlet.

Weather–compensated control unit (cont.)
Heating mode
The control unit determines a set boiler water temperature subject to the
outside temperature or room temperature (if a room temperature-dependent
remote control is connected) and the
slope/level of the heating curve. The
determined set boiler water temperature is transferred to the burner control unit.
From the set and actual boiler water
temperatures, the burner control unit
calculates the modulation level and
regulates the burner accordingly.
The boiler water temperature will be
limited:
& to 74 °C by the thermostat inside the
burner control unit.
& to 82 °C by the electronic temperature limiter inside the burner control
unit (during DHW heating to 87 °C).
& to 100 °C by the temperature limiter
in the safety chain (interlocks the
