You want to add some extra warmth and ambiance to your home, but don't have the time or money for a full fireplace installation.

A traditional fireplace can be a beautiful addition to any home, but they can be expensive and time-consuming to install.

Looking for a vent-free burner that produces stunning, realistic flames? Then look no further than the Monessen PH Series 18-Inch Vent-Free Burner. This cast iron burner features front and rear flames that dance and flicker beautifully, adding both warmth and ambiance to any room in your home. Perfect for use with the Mountain Cedar 6-piece Multi-Log Set

It's available in both Natural Gas and Liquid Propane, so you can choose the one that best suits your needs.

The Manual Ignition system uses a mechanical or battery-operated Piezo ignitor. Simply press the ignitor button to generate a spark and ignite the pilot light.

The Millivolt ignition system is remote-ready and comes with a manual variable flame height control and On/Off switch, so you can quickly shut off the gas if room oxygen levels drop to unsafe levels.
