Thank you for purchasing an A2000 Series water heater/boiler from Green Boiler Technologies. Your model
was proudly built in the United States with high quality components and craftsmanship. With the proper
installation and maintenance, your A2000 heater/boiler will provide years of outstanding performance.
The A2000 series water heaters and water boilers utilize efficient copper fin-tube heat exchangers and are
certified as Category I Appliances. Category I equipment utilizes natural draft to remove flue gases without need
of a fan or draft inducer, and has flue gas temperatures more than 140° F above the dew point.
The unique design of the appliance provides excellent heat transfer and a small footprint. The heat exchanger
resists build-up of lime scale and allows de-liming without disassembly of the unit.
