There is Primary and Secondary Combustion with air controls. Primary air enters via the air vent at the bottom of the door and feeds the fire from under the grate. Secondary air enters via the air vent above the door and is used for Secondary combustion and for the pre-heated air wash system that keeps the glass cleaner for longer. The Yandi also has an excellent overnight burn system. Its airtight door gaskets and manually controlled air vents allow you to close the stove down overnight. All you need to do is reopen the air controls, add fuel, and watch the fire roar again in the morning.
The large combustion chamber is lined with vermiculite firebrick and comfortably loads 50cm logs. There are heat resistant fire rope seals on the door, a cast iron baffle plate and a cast iron, multi-fuel ash riddling grate. The ash pan is removable for an easy clean. Included is an ash pan tool for ash pan removal; a glove for opening the door and adjusting the air levers; and an instruction manual. The legs of the Yandi are removable.
The Yandi is a high-end product manufactured to European design, in China, for the U.K. market. It is CE and British Standard EN approved and comes with a 5-year limited warranty.
