The heat builds up pressure inside the cylinder, which may cause the pressure relief valve to release propane. Flash fires or explosions can result from exposing cylinders to heat. NEVER store or place a spare cylinder under or near a barbecue grill. DO NOT smoke or have any ignition sources such as flames […]
