You changed the tank, opened the valve, lit one burner, and got a two-inch ribbon of flame. On a Spirit this is usually the excess-flow device in the regulator: it saw a sudden rush and choked the line.
Same physics as the generic regulator reset. Spirit-specific notes: where the hose lives, how the QCC1 handwheel seats, and when the hose-and-regulator is worth replacing.
Safety
- Outdoors. No smoking.
- If you smell gas after a reconnect, shut the tank and stop.
- Soap-and-water on joints — never a flame.
- Lid open when you light.
Reset
- All knobs off, including the side burner on SX models. Off means the diamond or the word OFF.
- Shut the tank valve.
- Disconnect the QCC1 coupling. A brief hiss of trapped pressure is normal. A continuing hiss is not — stop.
- Wait one minute so the excess-flow seat can relax.
- Reconnect hand-tight until the collar stops. Do not wrench. A crooked start cross-threads.
- Open the tank valve slowly — a quarter turn over a few seconds, then the rest.
- Soap-and-water the tank-to-coupling joint. Growing bubbles: shut the tank, reseat. Still bubbling: tank or coupling, not the burners.
- Lid open. Light the first burner, high, one minute. Then open the others. You should see full-length blue flames.
Still tiny on every tube?
- Try a second tank. Exchange tanks are sometimes empty or have a bad valve.
- Two tanks, same ribbon → regulator likely failed (water inside, cracked diaphragm, hose kinked under the cart).
- Search Amazon or BBQGuys for Weber Spirit regulator hose and match the grill-end fitting. We do not invent a hose ASIN.
What this will not fix
- One burner dead, others fine: tube, orifice, or valve.
- Yellow flames on one section: ports.
- Click, no light, stick lights a strong flame: igniter.
- Natural-gas Spirits do not have this LP excess-flow dance. Do not swap LP parts onto NG.
After a reset that worked
- Open the tank slowly every time.
- Light one burner before you open the rest.
- Do not open the tank with a knob already on.
