    17. Slow fires: it is not recommended to burn the Heco Cookstove more than necessary early in the fall and late in the spring, as you cannot keep the fire box hot enough to burn gasses (without overheating your home). Slow fires can cause excessive creosote buildup in the firebox, stove pipe and chimney.
  • Page 5 OPERATION & WORK PRACTICE STANDARDS Testing Cookstove Draft Before Lighting To test your draft, place a piece of newspaper inside the cookstove fire box and light it. Pay close attention to the direction of fire’s flame and smoke. If the smoke is drawn up into the stove exhaust, your draft is working properly. If the smoke spills out the door, you do not have proper draft.
