1. What is a gas fireplace and how does it work?

A gas fireplace is a modern alternative to traditional wood-burning fireplaces. It is designed to offer the ambiance of a fireplace without the hassle of wood or the mess associated with burning logs. Here’s a detailed breakdown of how it works:

1.1 Gas Supply

A gas fireplace operates using either natural gas or propane, which is delivered to the fireplace through a pipe. The gas is then ignited by a pilot light or an electronic ignition system.
