These direct-vent fireplaces draw in fresh outside air to support combustion and exhaust combustion by-products to the outdoors. The Madison's vent-within-a-vent isolates the incoming fresh air from the exhaust, yet still requires just a
single hole through the wall or roof.

Madison fireplaces are heater rated, with a maximum Steady State Efficiency of up to 83 percent for Deluxe and Premium models. Millivolt models will provide heat even when ice or snow brings down your electric power lines. Intermittent pilot models require 110 Volt AC. Louvers at the top and bottom help circulate the
warmed air. All controls are discreetly concealed behind the lower louver.

Deluxe and Premium fireplaces may be upgraded to include factory-installed Aged brick liner, blower, or both. An optional Herringbone Brick liner features lighter color bricks, artfully smoked to enhance the realism. All models include glowing embers and lava rock for the ultimate in realism.
