The purpose of a flue box is to collect the flue gases emitted by the gas fire and direct them into a chimney for safe exhaust to open air. It is an open fronted metal collector box which fits behind the fire with an outlet to which the flue is attached. Versions are available which enable the fire to be fitted either to an existing chimney or to situate the fire where no suitable chimney exists.

For existing chimneys the flue box is normally connected to a flexible chimney liner. Rite-Vent’s unique new Fast-fix spigot makes the job much quicker and easier than before. Fast-fix greatly reduces the need for expensive builder’s work and costly reparation after completion of the installation.

For rooms without a chimney a gas fire can be fitted using a flue box and a rigid twin wall chimney. B Vent is ideal for most situations, although some decorative gas fires require a larger flue in which case an ICS or ICID chimney should be used.
● With the appropriate flue box the flue can be routed either in the same room or an adjoining room.
● The flue box has a twin wall construction to provide insulation and minimise the risk of condensation.

Manufactured with a ceramic inner wall, which simulates a fireplace opening, and a coated steel outer casing. Suitable for decorative gas fires with a heat input not exceeding 8kw. For appliances complying with BS EN 509: 2000.
