Multi-Story Fireplaces

Draft control in multi-story fireplaces can seem impossible. Especially when there are many fires burning at the same time, as in a condominium or apartment where there are individual chimneys.

The ENERVEX Multi-Story Fireplace Exhaust System is a single exhaust system that can deliver optimal draft for up to 25 fireplaces – regardless of how many fires are burning at the same time.

These draft control solutions uniquely monitor the operation of multiple fireplaces with a modulating high-temperature exhaust fan, variable-speed pressure controls, and automated gas controls. So the building not only looks great, but feels and operates great – with no safety worries.


  • No need for individual chimneys, vents & unsightly terminations
  • Space savings, design flexibility & installation cost savings
  • Less noise, more peace & comfort
  • Less energy consumption
  • Integrated on-demand pressure & safety controls
  • Long-lasting construction
