Direct Vent Gas Fireplaces

Coaxial vent system of a pipe inside a pipe (generally 4"/7") the inside pipe is for exhaust while the outer pipe brings in outside air for combustion.  The design of these stoves allows for a completely sealed system that does not compromise the inside air quality of your home.  It also lets you vent a product horizontally (great for when an appliance is installed on an outside wall).  Direct vent appliances are usually limited to a length of 40 ft (with a maximum horizontal length of 20ft) that will allow an appliance to function properly.
