What is it ?
Direct Vent Gas Fireplaces do not require a chimney and can be vented directly through a wall or roof. The direct vent draws its combustion air from outside while venting to the same outside atmosphere - thereby not consuming warm house air, nor competing with other appliances and furnaces for combustion air. Direct venting also eliminates drafts and heat loss associated with other fireplaces.
A direct vent fireplace can be a wonderful choice for rooms in which a traditional fireplace is not practical or possible. Aside from providing clean warmth and the cheery glow of real fire, it saves space by allowing furniture to be positioned directly to either side with "zero clearance." This simply means that while heat is radiated out the front glass, the sides are safe for combustibles to butt up against the firebox. The fireplace can also be optionally inset into a wall.The venting system of a direct vent fireplace consists of a double wall pipe, or pipe-within-a-pipe. The inner pipe provides venting to the outside, while the outer pipe carries outside air into the fireplace. As the outside air is sucked into the venting system, it's heated by the hot central venting pipe, improving efficiency. Though this type of fireplace does not require electricity, it does require a propane or natural gas pipeline for fuel and burns logs specifically made for direct vent models.
A direct vent fireplace can come in many configurations with various kits and trim. Some kits are designed to look like a traditional fireplace, complete with mantle, while others are more modern. Many carry the certification of wall gas furnaces, and their flexibility makes them extremely popular. Prices vary depending on manufacturer, installation needs and model, but in general they are far less expensive than installing a traditional fireplace, while providing many advantages. If you've always wanted a fireplace but didn't think it was possible & or considered the traditional fireplace too messy & you might consider a direct vent model. It could be just what your home needs for those crisp winter nights
Once a direct-vent fireplace flue is installed, one of the most challenging aspects of your fireplace installation is complete. This is one of the most important tasks because the direct-vent flue exhausts toxic smoke, gases and fumes from the system and draws in air from the outside for proper combustion. The direct-vent fireplace flue does not require interior air to work properly. Once you have determined the type of installation method, make a plan. This will help you visualize and clarify what you will require to complete the direct-vent flue installation as easily and quickly as possible. Also know the type of kit you & need for the flue installation method you select.
For horizontal connections, secure the direct-vent pipe to the port at the rear of the fireplace. When you buy the required kit for an outside wall installation, it usually includes a 24-inch verticaldirect-vent flue pipe and an adjustable direct-vent pipe. The kit should also contain a 90-degree elbow, wall thimble collar and a horizontal vent cap. If you do not want the fireplace flue pipe visible in the interior living space, eliminate the vertical length and vent from the rear of the fireplace straight through the adjacent wall. If you run your direct-vent fireplace flue through the roof, you'll need to measure the run and purchase enough direct vent flue pipe. Most vertical runs are limited to 30 to 35 feet.
