Whatever the thickness of the material, you must ensure the unit projects forward from the framed opening enough to compensate for the thickness of the finishing material if you are looking for a flush installation. Many installations will be finished out with standard 1/2 inch drywall up to the edges of the unit, but tile veneers and stone veneers are also popular. It's at this time that the consideration for finishing material thickness should also be made. Once this preliminary work has been completed the installation itself can commence. Collecting quotes from reputable local businesses for this initial work will leave you in a much better position to determine the overall cost and timeline of the project. It must also be determined how a gas line and electrical service if needed, will be routed to the installation location. A tech will be able to assist you in putting together the needed list of components. Those venting components are specifically tested and approved by a major listing agency to ensure safe fireplace operation. Most gas fireplaces will list the approved venting components in the instruction manual, and it's crucial that only those components be used. It is important to know the overall width, depth, and height of the intended installation area, as well as the overall ceiling and roof height. In the long run, making that call will greatly help with your gas fireplace installation. The sheer number of designs and different venting types can be a bit overwhelming at first, but narrowing the selection down to a unit that will fit your requirements can typically be accomplished in a single phone call.

This will include the framing dimensions, venting requirements, clearances to combustibles, and other preparations needed prior to installation. As with any installation of a home appliance, a detailed instruction manual will be provided that covers many pertinent construction details. Most fireboxes use external metal standoffs to ensure proper spacing is maintained. Because heat naturally rises, additional space above the fireplace is also required. For instance, a wood burning fireplace with an advertised 36 inch wide viewing area may have a framing dimension of 40 inches wide overall. The need for the air space and outer fireplace jacket means that additional space will be needed to fit the appliance into your intended location. The air space between the inner and outer jackets, and the ability for the unit to dissipate heat is what allows a prefabricated fireplace to be installed into a combustible enclosure framed from commonly available dimensional lumber.Īs you may have surmised, the advertised width of a wood or gas fireplace will almost always be in reference to the physical opening of the inner firebox chamber. Wood, gas, and electric units will all utilize an inner firebox chamber that is suspended by means of metal supports from an outer fireplace jacket. The modular design offers a cost-effective alternative to a traditional site-built masonry fireplace. Factory-built fireplaces are a prefabricated sheet metal system that relies on clearances to combustibles to operate safely. Regardless of the fuel type, there are common design aspects of all factory-built fireplaces that must be taken into consideration when planning a DIY installation.
