Checking the CO2 settings

Vitodens 333 is set up in the factory for natural gas E, and can be converted to

natural gas LL or LPG P using a conversion kit.

During commissioning o r maintenance, check the CO

2 level at the boiler adap-

tor.

Note

The MatriX burne r for Vitodens 333 is pr eset for the entire ga s group. Therefo re,

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 and

8.5to10.5%forLPGP.

Compare the actual CO

2 value with the above CO2 value range s for the indiv i-

dual gas groups (check the gas group with your mains gas or LPG supplier).

If the actual CO

2 valu e deviates by mor e than 1 % for natura l gas or 0.5 % for

LPG, proceed as f ollows:

Check whether the correct gas restrictor has been installed.

Check the balanced flue system for soundness, see page 18.
