Stove ventilation

All stoves require ventilation to burn safely and correctly,  Although stoves require considerably less ventilation than open fires and therefore produce very little in the way of room draughts while burning, each stove installation must still account for the air permeability of the house. Air permeability is the general seepage of air into the house via air vents, doors and windows etc, When a solid or multi fuel stove is installed it needs meet building regulations in terms your property's air permeability.


New builds, sealed properties and direct air supply

Due to building regulations all airtight or new build properties are sealed and require an air vent permanently open to the outside.

Our direct air or external air kit allows the stove to be installed in a room that may otherwise be sealed to the extent that would prohibit the correct and safe burning of a wood stove. This may also apply to houses in general sealed to a very high level to meet various energy efficiency targets.

The air duct is fitted onto the stove around the air inlet control and is fed from the supply tube on the rear face of the duct assembly. The inlet tube is designed to accept a flexible metal air duct pipe with an external diameter of up to 4 inches.

The surface area of the spigot connection to these (often a diameter of 4”/102mm) can then be deducted from the overall minimum ventilation requirement to satisfy Building Regulations.
