When the log set is ignited, a flame is produced that dances over the ceramic log set, creating a near-life-like wood burning experience. The log is installed inside an existing fireplace. The pipes pump gas fuel through holes in the logs. The logs can be placed in many different setups depending on the desired ambiance. Gas logs mainly comprise the set of ceramic logs and piping. The gas log sits inside the fireplace to create a wood fire experience. The only thing you need to remember is that gas logs are hollow perforated imitation (often ceramic) logs used as a burner in the fireplace. Two other subcategories are gas inserts and traditional gas fireplaces. Ventless gas logs are a subcategory of vent-free gas fireplaces. There’s neither an air intake vent nor an exhaust flue. Although they also run on either natural gas or propane (some are even dual-fuel, capable of running on propane or natural gas with a few modifications), the two flues/vents mentioned above are missing. Ventless gas fireplaces are slightly different. Meanwhile, the second is an exhaust vent that safely removes exhaust gases generated inside the fireplace. The first vent draws fresh air (rich in oxygen) from outside the house to aid the combustion. More importantly, it’s characterized by two vents running to the exterior of the house. The traditional vented gas fireplace can be fueled by either propane or natural gas. There are two broad categories of gas fireplaces – the traditional vented gas fireplace and vented gas logs. So, what about carbon monoxide and sulfur dioxide, one would ask? Wouldn’t that create a considerable risk to the home’s occupants? We find out shortly. These fireplaces don’t need a chimney because they don’t need to vent the exhaust gases. This is where a ventless gas fireplace comes in handy. But here’s the question – what happens if you don’t have a chimney? Many homeowners use the existing chimney to run the flue. In traditional gas fireplaces, similar to conventional wood fireplaces, an exhaust vent (flue) is incorporated into the fireplace to remove harmful fumes from the home. However, gas fireplaces come with one major challenge – the risk of oxygen depletion. You never have to worry about messy ashes and soot left over by burning wood. Gas comes with multiple advantages, including greater availability and reduced maintenance. While wood-burning fireplaces are the dream of most homeowners, most of today’s new fireplaces are fueled by gas.
