Buying Guide

• Round inserts (12–48"): Match traditional masonry fire pit shapes
• Square inserts (12–48"): Modern minimalist enclosures
• Linear inserts (24–72"): Long, narrow flame profiles for dining-table designs
• Match-lit vs electronic ignition: Match-lit is simpler/cheaper; electronic adds remote and safety shutoff

Frequently Asked Questions

What is a fire pit insert?

A fire pit insert (also called a burner kit) is a manufacturer-engineered gas burner system designed to be dropped into a custom-built fire pit enclosure. It includes the burner ring or pan, gas supply hardware, and (optionally) electronic ignition components.

How deep should a fire pit insert be?

Most round and square inserts require an enclosure depth of 8–14 inches below the burner pan to accommodate the gas valve, supply line, and air mixer. Always follow manufacturer specs.

Do you need a liner for a fire pit?

For wood-burning pits, yes — steel or stone liners protect the enclosure from heat damage. For gas insert pits, the burner pan itself acts as the liner; no additional liner is needed.
