How Do Direct Vent Fireplaces Work?

The gas fireplace has undergone a major overhaul since it first appeared on the market. In the early days, gas stoves and heaters were more common. Fireplaces were mostly decorative, and of little import when it came to heating. In the 1980s, with the implementation of direct venting, gas fireplaces began to surge ahead of old wood ones. This has become a very popular choice among those who are looking forward to installing a gas fireplace. So, how do direct vent fireplaces work?

What Is Venting?

Venting is a method through which combustion gases exit from the firebox of a heating device into the outdoors. Older wood fireplaces vented out through the chimney. In general, whether it is a fireplace, stove, or insert, two specific means are available for venting outside. These are:

  1. 1. Horizontally
  2. 2. Vertically
  3. 3. Both

The direction the venting occurs depends both on the product type and the fuel involved.

Direct vent fireplaces can be vented outdoors horizontally, vertically, or both. The device used is a double, or coaxial pipe exiting out of an exterior wall or roof. However, this type of fireplace does offer another option.

This technology allows for the pipe connected to a completely enclosed chamber to bring in fresh air for combustion, and using gravity, drawing out the gas and fumes. The air tight glass chamber around the firebox prevents noxious gas from escaping allows radiant heat to efficiently and effectively heat it.
