REPLACEMENT OF OVERPRESSURE SILICON DAMPER FOR COMBUSTION CHAMBER

The overpressures sillicon damper “G” for combustion chamber (fig. A) shall be replaced with a new one yearly (during the periodical 

maintainance) in order to keep the overpressure safety system efficient.

For replacement use the following instructions

•  remove the top

•  remove the first lateral ceramic covering / metal covering (in accordance with the model)

•  unscrew the screw-washer-damper-spacer shown in fig. A/C (operate same way on both sides)

Install the new kit as follows:

•  Prepare the screw-washer-damper-spacer alligned as shown in fig.C and screw them in the structure.

•  screw it completely

Check now the proper compression of dampers, using the gauge included in the kit:

•  lay the gauge on the lid (fig.B); the gauge has to lay completely, while the head of the screw has to be in contact with the gauge. If 

it’s not the case, register the screw accordingly.
