Rytons Gas Appliance Ventilation Calculator

Gas appliance ventilation
  • All our gas appliance ventilators have an equivalent area calculation as required by Part J of the Building Regulations.
  • The calculator is for gas appliance 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 appliance and positioned to access directly to the outside.
  • The calculator has options for the two most popular installations we are asked about.  For all other gas appliances refer to Part J of the Building Regulations or call our technical team for advice.
  • To get started input a few details about the appliance and the property into which it is to be installed.  Hit the Calculate button and a list of suitable ventilators will be generated.
