SF-3500-A Wood/Coal Hot-Air Furnace by Harman
Harman Hot-air Furnaces have three internal systems that help maintain a clean, consistent and comfortable temperature throughout your entire home: a complete automatic start and stop blower system, an automatic draft system with high limit control and a filter system to ensure clean air. All you have to do is set the thermostat! Harman’s sophisticated draft control system knows when to cause the fire to burn hotter and supply just the right amount of heat. And one simple adjustment lets you quickly switch from wood to coal.
