This Bromic Heating BH3030011 heat deflector will help protect your ceilings from your outdoor heaters! Designed to fit Tungsten 300 series heaters from Bromic Heating, this heat deflector directs heat away from ceilings and towards customers to maximize your heater's ability to heat outdoor patios, bars, and dining areas. This deflector also helps prevent damage to sensitive painted, plastic, or wooden ceilings in applications where minimal clearance above the unit is required. Heaters mounted within 3' 6" of a ceiling must use this deflector, but the deflector will not provide maximum protection if the heater is mounted closer than 14".
