When ample liquid propane is available, propane will vaporize sufficiently to provide operation between the temperatures of

• A. 30 to 90 degrees F
• B. 0 to 60 degrees F
• C. -20 to 40 degrees F
• D. 100 to 150 degrees F

Answer: (A)

Vaporizing enough propane to feed the burner depends on how much heat can be transferred to the liquid inside the tank. When there’s ample liquid propane, the limiting factor isn’t how much fuel you have, but how quickly heat can boil some of that liquid into gas to keep the burner fired. At moderate ambient temperatures, roughly 30 to 90 degrees Fahrenheit, heat transfer is just right: the liquid propane can boil and supply gas at a steady rate to match burner demands. If it gets colder, heat transfer slows and vaporization can’t keep up, so the burner may struggle. If it gets warmer, the vapor pressure rises and equipment is designed to handle typical operation within a safe range, but extreme heat can also push pressures higher than the system is intended to handle. Therefore, the best practical range for reliable operation with ample liquid propane is around 30 to 90°F.
