First, liquefied gas used in the gas heater must be pure propane liquefied gas, which is 5-10 yuan per can (15kg tank) more expensive than ordinary liquefied gas.(the main components of liquefied gas include propane, butane, propylene, butene and so on. Pure propane has better quality than liquefied gas and is much more expensive.Companies that deliver liquefied gas usually have propane and cheap liquefied gas, so you only need to buy pure propane gas.
Hazards of using cheap liquefied gas: 1. Small air pressure fire, usually after burning for 0.5 to 2 hours, the pressure will decrease rapidly, and the fire will become small and cannot be used normally.2. Long-term use of cheap liquid gas with impurities will cause the electromagnetic valve of the heater to fail or reduce the sensitivity.
