11. Check whether there is a burner pressure regulator (1) attached to the gas
control, or simply a blank plate (5).
Comment
If the supply pressure for a gas category is the same as the burner pressure
(see the gas data table (3.4.3 "Gas data") ) then the gas control must be fitted
with a blank plate with cork gasket. A burner pressure that deviates in
comparison to the supply pressure requires the use of a burner pressure
regulator with rubber gasket. Each conversion kit contains all the necessary
components.
12. If the blank plate or burner pressure regulator need to be replaced:
- Unscrew the connector (4) of the gas control.
- If necessary, remove the blank plate or burner pressure regulator (5)
or burner pressure regulator (1).
- If necessary, fit the blank plate or burner pressure regulator supplied
with the conversion kit.
- Fit the connector (4) of the gas control.
