The InstaTherm burners are constructed of ceramic fibers arranged in circular mats on an air box, enabling the burner to be fired in any orientation. Each burner is fabricated with a heat-resistant, high-density ceramic board. An air blower provides the optimum gas to air mixture using gas-air duct for combustion. Combustion takes place above the burner head where the temperature can reach up to 2000 F (1095 C) within a few seconds. The housing temperature remains at no more than 150 F (65 C). The burners are fired using electronic ignition. Its flat burner configuration allows the system to replace electric resistance heaters in many applications.
