Run-Time

Important Note:
Propane tanks are never filled to 100% due to expansion safety limits. They are typically filled to 80% capacity. So usable propane is:

• 250-gallon tank: 250 × 0.80 = 200 gallons usable

• 500-gallon tank: 500 × 0.80 = 400 gallons usable

• 1,000-gallon tank: 1,000 × 0.80 = 800 gallons usable
