Flue Box Twin Wall Freestanding 212mm Deep

Twin Wall Gas Flue Boxes

The Freestanding and Recessed Gas Flue Boxes are designed to be used with conventional Radiant gas fires, as well as Inset Live Fuel Effect (ILFE) gas fires, which comply with BS 7977-1: 2009.

As there are now so many of these available, it is perhaps understandable that confusion arises when deciding which gas appliance can be used with which gas flue box and flue system.

SFL provide several types of Gas Flue Box, all designed to be used with the IL Gas Vent System and, where Building Regulations allow, may be used with stainless steel chimney liners with adapters.

The Freestanding Gas Flue Boxes have a twin-wall construction and is for use with any Gas Fire manufactured and tested to BS 7977-1: 2009. This Standard includes both conventional radiant gas fires and appliances which simulate solid fuel and wood burning either behind glass or having an open front. Radiant fires and those with a simulated solid fuel fire behind glass and usually supplied with a closure plate as shown in the illustration above. Those having an open front, whether projecting into the room or sitting back into the fireplace opening and typically identified as Inset Live Fuel Effect Fires, or ILFE’s for short.

The Boxes must be positioned on a 12mm thick Building Regulation required non-combustible hearth.

A 125mm diameter IL Gas Vent System is then connected directly to the short IL spigot length which is a permanent fixture on the Box outlet.
