Propane problems are usually simple: gas supply, connections or wind. Work through them in order, and never force a valve, bypass a safety device or light a pit that smells strongly of gas. If gas smell persists, turn everything off, move away and call a professional.

The tank is empty or the valve is closed

Check the tank level and open the tank valve slowly and fully. A tank that feels light or a valve that was left closed after storage is the commonest cause of a dead pit. If the tank is empty, swap it for a full one and recheck.

Air is trapped in the hose after a tank change

After changing a tank, the hose may hold air that delays ignition. Open the valve, wait briefly, then try lighting as the maker directs, without repeated sparking into a gas-filled bowl. If the pit still will not light after a few tries, stop and check the connections.

A connection is loose or the hose is damaged

With the gas off, check every connection for tightness and look for cracks, kinks or wear on the hose and regulator. Replace a damaged hose or regulator with the maker's part, never with a generic fitting. If you smell gas at a connection, turn the gas off and do not light the pit.

Wind keeps blowing the flame out

Move the bowl to a sheltered spot, use a wind guard if the maker offers one, and light on a lower flame before raising it. A light gas flame in an exposed spot will not stay lit, however healthy the pit is, and raising the flame in wind mostly wastes gas.

The burner or lava rock is clogged

With the gas off and the pit cool, clear debris, ash and displaced lava rock from the burner ports. A clogged burner lights unevenly or weakly, and lava rock that has shifted can block flame paths. Reset the rock bed evenly before relighting.

Questions, answered

Is it safe to keep trying to light a propane pit?

No, not repeatedly. Each failed attempt can fill the bowl with gas, which can ignite suddenly. Try a few times as the maker directs, then stop, ventilate, check the supply and connections, and only then try again.

Why does my propane pit light but burn low?

Low flames often mean low tank pressure, a partly closed valve, a clogged burner or strong wind. Check the valve and tank first, then the burner and the wind, in that order, before assuming the regulator has failed.
