The Oakport 18 comes two ways. Same firebox, same looks, same venting; both keep working in a power outage. The difference is how it lights and what comes in the box.


About the Oakport 18 Millivolt
Millivolt (standing-pilot) model: no electricity required — keeps working in a power outage. Fan kit and remote or thermostat are NOT included; add them under Optional Accessories.
Free Standing Gas Fireplaces Offer Exceptional Versatility Because the free standing gas fireplaces that we offer are direct vent, there's no need for a chimney or traditional fireplace in which to install them. A direct vent model can connect to the exterior of your home through venting, allowing outside air to circulate around the firebox. This opens up a wealth of possibilities for location, enabling energy-efficient warmth in almost any room of the house. Even homes that weren't originally constructed to accommodate a gas appliance are often suitable for the installation of a free standing gas fireplace. Low on Fuel, High on Output Certified as having 75% efficiency for natural gas and 77% for LP gas, the Oakport 18 offers impressive performance. Rated at 24,500 BTU/hr input for both natural gas and LP gas, this is a free standing gas fireplace that benefits from both excellent performance and eye-catching good looks. Fronted by traditional glass, this gas fireplace includes a limited lifetime warranty and offers exceptional value. Range of Engaging Features on Our Free Standing Gas Fireplaces In addition to its versatile nature and excellent fuel consumption rates, the Oakport 18 also has traditional legs and an engaging screen front. Several different methods of control can be used with this model, including a touch screen, portable thermostat control, a wireless wall switch, and a wireless or mounted thermostat control.
