Waste Gas Burner- Candlestick, Auto/Manual Ignition

The Groth Model 8391B Waste Gas Burner includes an ignition system with all of the best features available in a waste gas burner. The burner wind shield contains the unique “downdraft prevention” with a bevel design which substantially eliminates the possibility of the flame being blown out. The design also provides the proper air/fuel mixture to ensure an efficient burn. The wind shield will deflect outside winds, up to 150 MPH, and operates efficiently in heavy rains preventing smoke and odors from permeating the surrounding area.
