Low flame on all burners

Every burner tiny and blue usually means excess-flow lock or a near-empty tank — not four failed tubes at once.

LP tank, regulator, and hose Propane tank, QCC1 handwheel, regulator body with excess-flow device, hose to the manifold. LP TRAIN · TANK → VALVES 1 LP tank 2 QCC1 handwheel 3 regulator excess-flow inside 4 hose 5 manifold / valves Open the tank slowly, knobs off. Fast-open trips the excess-flow → tiny flames.

If every main is a 1-inch blue ghost, start with fuel delivery: tank vs regulator and regulator reset. Yellow lazy flames are a different page: yellow-orange.

Procedure

  1. Confirm the symptom is all burners, not one.
  2. Exchange/refill if the tank is light.
  3. Slow-open reset of the regulator.
  4. Light one burner on low, lid open.
  5. Soap the tank-to-regulator joint.
  6. Still low after a known-good tank: regulator/hose replacement search.
  7. NG outdoor kitchen: NG leak check — different symptoms.
  8. One burner recovers while others stay low → manifold/valve issue, not the tank.

Pull stamped Char-Broil tubes, match length and inlet, reseat on the orifices, and leak-check. Universal tubes that are short are how flashbacks start.

Measure tent length and width on Performance and Commercial carts. Heat plates are the drip shields — when they lace, burners die. Do not buy by lid name alone.
