The Mantis stands alone as the most efficient fireplace you can buy. The concealed three-stage heat exchanger captures more than 90 percent of the heat energy from the burner and directs this warm air into your home - not up the flue. With so much of its heat extracted, the exhaust can be vented outdoors in conventional PVC piping - saving money, labor, and space on installation compared to traditional direct-vent systems.               

The Mantis puts the green in environmentally friendly. Its powered inlet/exhaust blower ensures the
optimal air/fuel mixture for consistently clean-burning operation under any conditions.

As the first condensing vented gas fireplace certified for use in the U.S., the Mantis is unique. The certifying agency drew from multiple national standards to test and certify it. With the vast majority of the heat delivered to your room, the top and sides of the Mantis stay cool-to-the-touch - so cool, in fact, it earned a zero-clearance certification for installation against any combustible building materials.

The dual burner delivers 9,000 Btu (front only), 19,000 Btu (rear only) or 28,000 Btu (combined). Operating the front burner alone lets you enjoy the ambiance of the attractive log set and gas fire without overheating the room. But, when the temperature dips, the Mantis rises to the occasion, switching on the second burner to produce maximum heat output.

Humidify While You Heat

Condensed water - a by-product of the Mantis's super-efficient heat extraction - is captured and then evaporated to introduce humidity to the room air. The automatic blower gently diffuses the humidified air into the room. The result is a more comfortable home environment, fewer complaints of dry throats, and less frequent static electricity discharges as you move about the room.

Advanced Solid-State Controls

The sophisticated control system monitors every critical aspect of the Mantis's operation to maximize efficiency, comfort, and safety. For all its advanced technology, the system is amazingly easy to operate, with just two on/off buttons for the two burners you can set the temperature to low (front only), medium (rear only) or high (both burners). Or, choose the optional programmable thermostat to deliver the right amount of heat for each day of the week and time of the day. The Mantis automatically purges unburned gas from the combustion chamber after each burn and before each ignition for controlled, even starts every time. The automatic fan cycles on only after the Mantis reaches operating temperature and continues blowing as long as it senses warm air. You never feel a cool draft, just warm, humidified air.

Versatile Installation

The Mantis may be installed in an existing fireplace as an insert or as a zero-clearance system with a wood cabinet mantel or, with the optional pedestal, as a freestanding stove. With the exhaust and intake pipe made from PVC and a blower controlling the flow of air and exhaust, the venting options are numerous. Install the Mantis as a direct-vent or ambient-vent system with PVC pipe.
