Do you mean you want to place the stoker over a piece of plywood? Even if allowed I wouldn't consider doing that. I don't know about that particular unit but the larger stokers like the EFM's or my Van Wert don't have a bottom. Hot ashes could ignite the wood. Even if it has a bottom you're still running a risk. Any combustible material should be kept away from any stove that burns solid fuel.
