The Installer works with the customer to assess the project and fill-out the application, signed off by the customer. The Project Application includes information about the home, existing boiler, and the biomass boiler being installed with the Manual J calculation attached. Once the application is received and meets the program requirements, NYSERDA will approve the application and notify the Installer. Project Application Process
