How do I keep rain and water out of a fire pit burner?
Three things do the work: a fitted cover when the pit is idle, a burner pan that drains instead of pooling, and media — fire glass or lava rock — that lets water pass through to the weep holes. Standing water in the burner tube is what corrodes ports and floods the igniter, so keep it draining and covered and you've won most of the battle.
The cover is your first line
A snug, breathable, fitted cover keeps the weather off between fires, and out here that matters — mountain afternoons turn to downpours fast. Skip the cheap tarp. It traps condensation underneath and holds moisture right against the burner, which is the opposite of what you want.
Get one sized to your pit so wind doesn't lift it and rain doesn't drive in at the seams.
Drainage matters more than people think
A well-built gas fire pit has weep or drain holes in the pan so water runs through instead of collecting on top of the burner. Fire glass and lava rock help here too — they let rain filter down rather than damming it on the burner tube. If your pit pools water after a storm, that's a drainage problem worth fixing, not just covering.
After a real soaking, run the burner a few minutes to dry things out before you put the cover back on. Heat drives the last of the moisture out of the ports and igniter.
When water's already gotten in
If the burner has been sitting wet through a wet mountain stretch — and WNC hands out plenty of those — you may see rusty ports, a weak or uneven flame, or an igniter that won't spark. Surface debris you can brush out yourself with the gas off. Corroded ports, a rusted burner, or gas-side trouble is a service call. Reach us at (828) 545-0525 and we'll sort it out.
