Generator in vertical version
•
Stop the generator and discharge it.
•
Disassemble the burner.
•
Detach the chimney pipe union and hermetically close the generator connection with blank flange and
rubber gasket.

Wait 24 hours then drain completely through the lower plug; then fill and rinse the generator with clean
water. Wait some time for the inside of the generator to dry then reassemble the components.
•
Lubricate the thread of the internal plug with graphitised grease and screw it up tightening moderately.
•
Close the door, detach the blank chimney closing flange and reassemble the union section.
