Chimney

• Vintage chimneys and fireplace enclosures should be "inspected and cleaned by a certified chimney specialist," according to the U.S. Fire Administration.
  
  

Fuel

• Fuel selection is critical for safe fireplace operation. Large logs and paper trash should never be burned in a vintage fireplace.
  
  

Fire Size

• Small fires are more efficient and safer in older fireplaces than larger fires that burn fuel less effectively and produce additional smoke.
  
  

Chimney Liner

• OldHouseWeb.com recommends having a professional replace the chimney liner in the old fireplace.
  
  

Chimney Caps

• Older chimneys were not constructed with spark arresters that are now required by local municipalities, but this is an important safety feature, according to the Hearth, Patio and Barbecue Association. Modifications may be necessary to the vintage chimney to install the caps.
