There are 7 vermiculite bricks in a Woody Eco multi-fuel, you can purchase them individually or in a set:
- left side,
- right side,
- back bricks top pair,
- back brick bottom pair and
- throat plate brick.
These are different to the bricks in the non Ecodesign Woody. If you are not sure if your Woody is Ecodesign or not, look at the handle. On the Ecodesign Woody the mechanism is hidden, only a slot is visible. The original Woody, that is not Ecodesign, has an external handle latch on the body of the stove.
Once you have confirmed that this is an Ecodesign version: to identify the multi version, look upward to the roof of the firebox, if you see two rectangular grids, this is the catalytic converter version, if there are no grids this is multi fuel.
