  • Wood Stove Season.  Protect the health of your family & neighbors.  EPA’s Burn Wise program provides tips for burning the right wood, the right way, in the right wood-burning appliance.  
    • ​Never burn wet wood or trash in your fireplace or wood stove. By burning dry firewood, you can save money and protect your family's health.  See Video...
    • ​Don’t let the fire smolder! Open the dampner and burn dry wood.  A smoldering fire produces less heat, more smoke & more creosote buildup.
