*Heights quoted are from ground level to bottom face of firing tube.

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.
