WARNING
DO NOT install Centrotherm Innoflue venting components with any other manufacturer’s vent components.
Centrotherm Innoflue components must be used exclusively throughout the entire venting system from the water
heater coupling or vent connection to the outside wall or ceiling near the vent terminal location.
This supplement is intended only for additional information for installing Centrotherm Innoflue single wall venting
system and the instruction manual supplied with the water heater must be followed for the detailed information
provided for the venting system installation.

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.
