20-CLEANING AND MAINTENANCE
REPLACING THE OVERPRESSURE DISCHARGE FOR THE COMBUSTION CHAMBER
Overpressure rubber bushing “G” of the combustion chamber (fig. A) may get worn and/or damaged, it is therefore necessary to replace it
once a year to ensure correct system operation.
To replace it, follow the instructions below
• Raise the front door and if necessary remove the side panel
• Unscrew the screw-washer-rubber bushing-roller shown in figure A/C (on both sides of the cover). It is now possible to assemble
the new kit:
• Prepare the screw-washer-rubber bushing-roller aligned as shown in fig. C and screw them into the structure.
• Tighten the screw all the way.
Now ensure that the compression of the rubber bushing is correct using the template supplied with the kit:
• Place the template on the cover (fig. B); the head of the screw must be touching the element above it. If necessary, tighten or loosen
the screw so that this occurs (the image is indicative).
