Brief criteria would be:
– Safety system (The burner rack cannot be used if it is not inverted.)




– Cartridge reject system. (When the pressure was too high, the cylinders would be automatically rejected)
Some suppliers have already cancelled this part. It’s extremely dangerous.
– Structural strength (Like for the burner stable and assembling stability. I will provide more pictures for comparison)


– Width of the galvanized sheet at the bottom (On the videos, you can find out why it is important.)

– Weight of Stove Sometimes you can weigh the products.
– Thickness of the Raw material It was almost impossible to measure, since the metal was covered by the plastic powder.
