DANGER: When this heater is in use, there is obviously a combustion process which generates heat to make hot water. The combustion of almost all combustible materials and flammable gases of any kind typically consumes a large amount of oxygen and in turn this combustion process produces many different by-products in the smoke (exhaust) which include Carbon Monoxide. Regardless of how clean the combustion process is, there are always exhaust gasses that are emitted at some level.
NOTICE: This heater is not designed to be mounted in areas outdoors or unheated structures if temperatures can drop below freezing. When the temperature of the room in which this heater is mounted drops below freezing the residual water must be drained from this unit.
