Factory recommended mounting heights are listed as a guideline. If infra-red heaters are mounted too low or too
high, they may result in discomfort or lack of heat. The factory generally recommends observing 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
recommended mounting heights.
