Danger!
Risk of poisoning due to increased CO

An incorrect gas restrictor size can lead to
increased CO values.
▶
When replacing the Venturi, ensure
that you use the correct gas restrictor
(colour coding and position of pins on
the underside of the gas restrictor).
Caution.
Risk of material damage to the product.
Lubricant can block function-related chan-
nels in the Venturi.
▶
Do not use lubricant when installing the
gas restrictor.
▶
Insert the gas restrictor for the type of gas in question
into the new Venturi (yellow: G20 natural gas, grey:

strictor matches the colour of the coding
resistor on the PCB.
When inserting the gas restrictor, ensure
that the gas restrictor is correctly aligned
using the indicated position marks on the
upper side of the Venturi and also the posi-
tioning pins (5) on the underside of the gas
