Direct vent is the most commonly used and newest method of venting, which was invented by Heat & Glo's founders in the 1980s. It is highly favored due to its efficiency, safety, flexibility, and the fact that it does not necessitate an existing chimney. When it comes to direct vent fireplaces, a couple of rigid flues are installed in sections ranging from 4" to 48" in length, along with 90°- and 45°- angled elbows that offer flexibility in terms of placement. The inner flue, which is 4" in diameter, is surrounded by an outer flue that is either 6 5/8" or 8" in diameter. During the start-up of the gas fireplace, the inner pipe allows the exhaust to pass through it to the outdoors, while the outer pipe brings in fresh air for combustion, transmitting it directly to the bottom of the sealed firebox, where the unit ignites. The outer pipe also aids in insulating surrounding combustible components from the heat passing through the system. The direct vent fireplace unit is completely separated from the air in your home, with a high-temperature glass panel and protective screen sealing it off from the interior of your house. The illustration shows the different routes that a direct vent can take, including through the wall directly from the firebox to the outdoors, as well as optional side and top venting routes.

Frequently Asked Questions

What is a direct vent pipe?

  • A direct vent pipe is when a large pipe is fitted with a smaller pipe in order to bring air in from outside and then exhaust combustibles back outside. 

Can a wood stove be direct vented?

  • You most likely will not have the ability to use a direct vent on a wood stove. Fireplaces or stoves that run on gas are able to use this type of venting due to the exhaust is less and they do not require as much air and are also sealed. Wood burning fireplaces or stoves require a chimney for vertical ventilation.
