Other features include
calorized steel emitter tubes for higher radiant efficiency and safety, a state-of-the-art step opening combustion gas valve for quieter ignition and a closed combustion chamber design and direct spark ignition system with 100% safety shutoff control.
The burner raises the temperature of the infrared emitter, a special heat-treated and
calorized steel tube that maximizes heating distribution efficiency.
