NOTE: The chimney ventilation system installation & permitting is the responsibility of Customer or General Contractor, not Marra Forni. Prior to ordering the local municipality should be provided with the specifications and material data of the direct vented chimney system and mechanical exhaust for the Neapolitan oven. The General Contractor or Subcontractor performing the installation is responsible for verifying the ventilation system conforms to the building's installation path and meets the overall length required. Additionally, the General Contractor or Subcontractor must ensure the roof's integrity, manage roof or exterior wall penetrations, and properly seal these areas. The General Contractor or Subcontractor must also adhere to the manufacturer's installation instructions and comply with local and national code requirements.
