The Azure Blue Flame Gas Cabinet Heater uniquely incorporates a full length tempered glass front. It is a powerful room heater with variable heat settings. The ODS (oxygen depletion system) safety valve and flame failure device means that the gas will cut off if the oxygen levels are too low or if the cabinet should fall over. Other features include built in Piezo ignition and castors for ease of movement. This product also has a back support for the gas cylinder.
