NOTE
The combustion chamber insulation panels in this boiler contain a cornstarch based binder which may emit a strong
odor as it is burned out of the insulation when the boiler is fired for the first time. An hour or more of continuous
firing may be required to burn off all of this binder. Open any windows and outside doors in the boiler room to
maximize ventilation while this binder is burned out.
