Is the Econoburn certified for indoor use?
Yes, Econoburn’s indoor model is safe to install indoors. Indeed, it can be installed with as little as 0″ clearance to combustibles on each side and 18″ clearance to combustibles in the back. In addition, the Econoburn boiler carries the ETL – WHI listing. WHI is the safety standard mark used by the solid fuel industry and is the legal equivalent of UL. WHI tests not only to UL standards, but also CSA (Canadian) standards, which are far more difficult to achieve.
