No other non-catalytic wood burning insert gives you extra long burn times and steady even heat like the Harman Exception Insert. The Exception’s non-catalytic design incorporates an afterburner which mixes air and wood gases at very high temperatures so that more complete combustion can occur. This design is so clean-burning that it meets tough EPA standards without the need for a catalyst, but more importantly it delivers very long even burning fires. Other non-catalytic inserts have air tubes above the fire which shortens the burn time and causes heat spikes early in the burn cycle. The Harman Exception Insert is more than an outstanding source of heat, it is also an attractive addition to your home. Various decorative options including choice of color, decorative tiles and hood let you choose a look that is right for your home.
