      When installing the heater on the ceiling, it is best to mount the unit in a level orientation so the reflectors will direct the heat straight down. Mounting the heater at a 45-degree angle will concentrate the heat towards the center of your patio space.

      For the best heating experience, a specified mounting height for each model can be found on the specs sheet.
