Typical Installation(Refer this if required)

 Refer to our Typical Venting Installation drawing to select the appropriate component.

  • The inner pipe diameter should match the outlet size of the appliance.
  • Check the appliance manufacturer’s installation instructions to confirm which types of vent configurations are permitted (i.e. horizontal, vertical, chimney reline, etc.). Also, check for any venting restrictions such as maximum horizontal run, minimum and maximum vertical rise, maximum offset, etc.
  • Be fire safe! Use proper support and bracing. Follow local building codes and have your venting system inspected.
