Regulations: Stove Ventilation in Northern Ireland
A good air supply is essential to the safe working of a heat producing appliance. The amount of air required will depend on the type of appliance, the input/output and the type of fuel it burns. For your convenience, we have created a stove ventilation calculator (see below) and outlined extracts from the following regulations:
- Building Regulations (Northern Ireland), Technical Booklet L (October 2012).
- For detailed guidance, refer to the full technical booklet available to download here.
Technical Booklet L: Combustion appliances and fuel storage systems
Regulation 70: Air supply
A combustion appliance shall be so installed as to receive a sufficient supply of air to ensure the safe and efficient operation of the combustion appliance and any connected flue.
Section 2: General provisions for combustion appliances
Permanently open ventilation of rooms
2.13: A permanently open air vent should be non-adjustable and be positioned where it is unlikely to become blocked. It should be so installed that the building occupants are not provoked into sealing it against draughts or noise. A permanently open air vent should not be located within a fireplace recess.
2.15: In a noisy area, it may be necessary to install proprietary noise attenuated air vents to limit the entry of noise into the building but these should not diminish the required air supply.
Section 3: Solid fuel burning appliances (including solid biofuel) with a rated heat output up to 50 kW
3.1: Any room or space containing a combustion appliance should have a permanent air vent opening of a size not less than that shown in Table 3.1. For an appliance designed to burn a range of different solid fuels, the air supply should be designed to accommodate burning the fuel that produces the highest heating output.

General notes:
- This calculation assumes the air vent will be in the same room as the stove and positioned to access directly to the outside.
- Rytons AirCore and AirLiner ventilation sets feature anti-draught systems to promote a comfortable environment in the room. Achieve further draught protection by placing the air vent close to the appliance or at a high level close to the ceiling.
- Noise attenuating Acoustic AirCore and AirLiner Ventilation Sets are available for areas close to continuous noise (e.g. a main road).
- Rytons through-wall stove ventilators have equivalent area calculations as required by Technical Booklet L and HETAS Guidelines.
- Rytons through-wall stove ventilators are HETAS Approved for use with solid fuel, wood and bio-mass appliances.
