Smoke control zones

[dfen5]

If I've got this right, any stove can be installed in a smoke controlled area providing it only burns smokeless fuels. Is this correct?

I've got a Defra approved Euroheat installed that burns wood 'n' smokeless a treat but I want something bigger that doesn't have defra approval in another chimney only for anthracite - if I've got this right providing I only burn anthracite or smokelss it's ok? The Euroheat only has a rotary griddle in the centre and as a result the anthracite around the edges doesn't get enough air to burn completely.
