WARNING
Use only water or Centrocerin lubricant for lubricating the gaskets and pipe ends to allow easy insertion. DO NOT
use any other kind of lubricant, since deterioration of the gasket may result, which may allow dangerous flue gases
to leak into the room. If the vent pipe needs to be disassembled after the gasket has dried, wet the joint thoroughly
to loosen the connection.
