1Double Layer Reflective Structure: Gas heater is double layer design inside and outside, which can retain heat and greatly improve thermal efficiency. The base of the heater can effectively keep the balance of the heater and can be easily fixed in uneven places in the field. 2Good Heating Effect: The heater is made of stainless steel, which is resistant to high temperature and can save gas, high efficiency, good heat effect and high thermal stability. All aluminum reflector can turn ordinary burning flame into radioactive heat energy. 3Protective Net: This outdoor heater is equipped with a protective net, which can effectively prevent accidental burns and safe to use. For your safety, please do not use in the tent or confined space. 4Fire Valve and Heating Network: Fire adjustment valve can freely control the fire strength. Stainless steel heating network makes the temperature rise quickly, and high temperature resistance, no deformation, durable. 5How to Use: Connect the heater to the flat gas tank and fix it. Unscrew the fire adjustment valve of the heater to release the gas, which can be slightly enlarged. Press the electronic lighter to ignite the fire.
