Installation

Flue Box Insulation

Condensation in the single skin flue box is minimised by insulating the outside of the box on site to comply with the appliance manufacturers installation instructions. Because of the air cavity in the twin skin box further insulation is generally not required.

Fitting a flue box into an existing chimney

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.

Fitting a flue box where no suitable chimney exists

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.
