NOTE:- Factory recommended mounting heights are listed above as a guideline. If infra-red heaters are
mounted too low, they may result in heat discomfort. It is generally recommended to observe the
recommended mounting heights to optimize comfort conditions. However, certain applications such as spot
heating, freeze protection, outdoor patio heating or very high ceilings may result in the heaters being
mounted outside of the factory recommended mounting heights. Clearances to combustibles must always be
maintained.
