5.4 HOW TO REPLACE THE BURNER INJECTOR
The gas replacement operation must be performed by
qualified personnel
. A
wrong, incorrect or imprudent installation of the gas circuit can cause very dangerous gas
leaks on all the circuit and in particular in the tampered areas. Moreover, use suitable
sealants on all fittings. If the type of gas indicated on the label does not match that to be
used, the appliance must be converted and adapted to the desired type of gas.
For this operation proceed as follows:
