Why do we need a full-duty cycle test that isolates start-up, SS, and end phases?
• 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.
