Rytons Open Fire Ventilation Calculator

Open fire ventilation
  • Open fires require a considerable amount of air to burn safely and efficiently.  Under-ventilating produces an incomplete combustion resulting in the production of carbon monoxide, plus the spillage of smoke and fumes into the room.
  • All our ventilators have an equivalent area calculation as required by Part J of the Building Regulations.
  • The calculator is for open fire installations in the UK and uses the ventilation requirements of the Building Regulations Part J to generate results.
  • We have assumed the air vent will be in the same room as the fire and positioned to access directly to the outside.
  • To get started input a few details about the fire and the property into which it is to be installed.  Hit the Calculate button and a list of suitable ventilators will be generated.
