Installation of your Bromic heater is possible in low clearance areas. A heat deflector is required for a low clearance installation. The clearance required above your heater is diminished from 3' 7" to 1' 1". The heat deflector absorbs the heat rather than let it escape upwards toward the roof or ceiling. This heat deflector is for use with your Bromic 300 Series regardless of whether it is installed in a wall mount or ceiling mount installation. In addition to protecting your home or establishment, the heat deflector will also provide additional protection from rain. It has a dual layer stainless steel construction.
