How do I clean the burner ports on a gas fire pit?
With the gas fully off and the pit cool, remove the fire glass or lava rock, then brush the burner ring with a stiff nylon or brass brush to knock loose soot, spiderwebs, and debris out of the holes. A toothpick or thin wire clears a stubborn port. Never enlarge or drill a port — that changes the flame. Vacuum the crumbs and replace the media.
Why ports clog out here
It's the same story as an indoor pilot: spiders and dust move into the burner over the off-season and plug the small holes. Clogged ports show up as a weak, uneven, or yellow-tipped flame, sometimes a faint whistle. A seasonal brush-out keeps the flame crisp and blue where it should be blue.
WNC's long shoulder seasons — cool evenings from spring through fall — mean pits sit idle for stretches, and that's exactly when the bugs move in.
The safe way to clean them
Confirm the gas is off and everything's cold. Lift out the media, brush the burner ring all the way around, and clear any plugged hole with a toothpick or a thin piece of wire — gently. Vacuum up the debris so it doesn't fall right back into the ports, then replace the media evenly without covering any holes.
One hard rule: don't ream a port bigger or drill it. The port size is engineered to the fuel and pressure, and opening it up throws off the flame and can make it burn unsafe.
Where DIY stops
Cleaning debris is homeowner work. Anything past that — the gas line, valve, orifice, or regulator — is licensed contractor work in North Carolina, and that's us. If the flame's still lazy, uneven, or sooty after a good cleaning, don't chase it into the gas train. Call (828) 545-0525 and we'll diagnose it and quote it before we touch anything.
