†Maximum heat output is based on reloading once every 3 hours with 24 inch long split white oak, with 20% moisture content. Output rate is fuel dependent and will vary with wood type, moisture content, size and reloading frequency. GARN® WHS units are certified safe to burn cord or slab wood, densified wood briquettes and air dried corn on the cob.

*Tested to ASTM-E2618
