Is there a minimum clearance distance required from the brick hearth walls that would surround it?

Thanks for your enquiry.

For installation of the OKO S1 bioethanol stove, the minimum clearance distance behind the stove to non-combustible materials such as brick is 5mm. We’ve checked the manufacturer’s manual and there is no specific distance stated for the sides, so we recommend allowing an air gap of approximately 100mm on each side to ensure adequate ventilation and heat dissipation.
