Venting a fireplace is especially complicated in retrofit installations, where it can be problematic to find a route for the chimney flue. Another issue with fireplaces concerns the energy loss.

Vented gas fireplaces are somewhat better at retaining heat, but modern homes are now being built so airtight that even a vented gas fireplace may create negative air pressure that hinders good exhaust. Air flowing out a chimney vent flue can even prevent combustion gases from other appliances from exhausting properly.
