Gas Inserts for Existing Fireplaces

If your home has an existing masonry or metal fireplace, there are easy and attractive ways to spark new life into it. Gas burning fireplace inserts from Rocky Mountain Stove & Fireplace fit into almost any traditional fireplace opening to instantly transform it into a warm and entertaining centerpiece.

Gas Fireplace Inserts are used to convert an existing wood burning fireplaces, both pre-fab (zero-clearance) and masonry, to a more efficient gas appliance. They consist of a Gas Log set installed into a Steel or Cast-Iron Heat Exchanger and are usually sealed on the front with glass - the exception being Vent-Free gas inserts which are usually open.  Many of these units have fans to move the heat, and are also available with remote controls, wall switches or wall-mounted thermostats.

These Gas Inserts are much more efficient than the Vented Gas Logs, and the sealed fronts (glass) provide an extra safety factor. Quality Gas Inserts can provide BTU outputs ranging from 10,000 to 40,000 BTU and can burn as high as 80% (+-) efficiency.

Most modern Gas Inserts are direct vent, which means they use a two-pipe system, one which brings combustion air into the insert and the other which vents the exhaust. With a direct vent, it is usually mandatory to completely line the chimney to the top with two Flexible aluminum or Stainless steel pipes. This assures proper balance of the intake and exhaust and assures safe operation.

Direct Vent Fireplace Inserts are by far the most popular and most efficient type of fireplace insert.

With direct vent inserts, the insert is sealed. The air that is used to generate the flame (combustion air) is drawn from outside. The fumes that are a byproduct of the combustion are also vented to the outside. In this way, air contaminated with combustion byproducts and unused fuel does not circulate in the home, and household air is not used to fuel the combustion process.

If you already have a brick or stone fireplace, or a factory-built fireplace, and you want to convert it to gas, then the most cost-effective solution is an insert. If you are remodeling a part of your home that never had any kind of built-in structure, then you need a Direct Vent fireplace that does not require an existing opening or chimney
