Optional Fresh Air Intake Kit

The optional Morsø 8843 external air kit allows you to connect this wood burning fireplace to exterior combustion air through the rear of the unit.

Fireplaces burn fuel to generate heat and require a continual source of oxygen in order to start and sustain combustion. Wood-burning stoves typically obtain this oxygen from the room in which they are located. However, it’s not always practical, or suitable, for wood-burning stoves to draw the oxygen they need from the room in which they are situated.

Whilst not every fireplace requires an external air kit, they are recommended for homes that have insufficient ventilation. The types of scenarios in which an external air kit is recommended include:

• if the room in which you are placing the fireplace does not have a non-closable vent
• if you live in a home which has been designed and built to Passive House standards
