This heater does not require 120 volt AC supply for operation of the burner but is highly recommended as a primary power source to eliminate the need for
4 AA batteries. Batteries should only be used as a secondary power source when power is lost within the home.120 Volt AC power is also required for the
optional blower.
NOTE: Even if the fan is not purchased with the unit, it is still a good idea to bring power to the receptacle box (provided with the unit) in case the
fan is installed at a later date.
(Do not cut the ground terminal off under any circumstances.)
