What Are Vented Gas Logs?
Understanding the Basics
Vented gas logs are designed to be installed in a wood-burning outdoor fireplace like a Ashland 50 from Majestic, Majestic Ashland 42 or a dedicated vented fireplace.
They burn natural gas or propane and require a venting system to expel the combustion byproducts, such as carbon monoxide, outside the living area.
How They Work
Vented gas logs are connected to a gas line and a venting system, typically a chimney or a direct vent through an exterior wall.
The venting system draws in fresh air for combustion and exhausts the harmful gases produced during the burning process.
I have explained here do vented gas logs produce heat to clear some common doubts on the topic.
Types of Venting Systems
There are two main types of venting systems for vented gas logs:
1. Natural Vent
This system utilizes the existing chimney or flue to vent the combustion gases. It relies on the natural draft created by the temperature difference between the indoor and outdoor air.
2. Direct Vent
In this setup, a horizontal or vertical vent pipe is installed through an exterior wall or roof. The venting system includes two separate channels – one for drawing in fresh air and the other for expelling exhaust gases.
