Incident narrative

SaferProducts.gov consumer incident report 20160607-8AE80-2147417983. Severity: Incident, No Injury. Product: Weber Genesis 310 (Weber Genesis 310 CNG grill). Incident: My Weber Genesis 310 CNG gas grill supply line caught fire on Sunday. The grill was completely destroyed and minor damage occurred to my home. The grill was not in use at the time and had not been in use for roughly 36 hours. As you can see, the grease is empty, the cookbox is relatively clean, and the origin of the fire is very clearly on the outside at the gas line. You can also see the melted wheel on the left side, which indicates the gas hose where it was near the ground was on fire. This is a defective gas line that seems to have started leaking underneath the cover. The combustion pattern is consistent with a gas accumulation under the cover below the velcro constraints beneath the side shelves. Splay patterns and flame spread are consistent with a fire point of ignition to the rear of the grill and in the gas line on the outside of the cabinet but roughly 2' from the supply line on the house. Weber states the supply line leaking from the center of the line was due to being left under pressure. The line, however, is designed to maintain pressure. ASTM standard indicates it should handle 105 psi for 10,000 service hours. The gas in my house is 0.26psi and the grill was installed approx. 8,900 hours prior. The line is installed per code and is a butyl core line, wrapped in corrugated steel, and covered in polyethylene. This is a clear defect. A storm was in the area, so ground static was high at the time. Weber states that this is an "act of nature", but a gas line that's not leaking won't ignite even under direct flame impingement. The product is unsafe and Weber refu
