* Per the National Electric Code heating circuits are considered a continuous load and therefore must be derated
by 20%. For example: a 20 Amp heating circuit can not have more than 16 Amps of load connected. If heater is
operated at 208V it will draw 13% less Amps and produce 25% less wattage.
** Assumes an 8 ft. high ceiling; Use cubic feet to estimate wattage requirement when ceiling is not 8 ft.
*** If area is larger than 720 sq. ft. / 5,760 cubic feet use more than one heater.
