Trianco TRG60 blocked flue (made worse by me!)

[Marc T]

We've just moved into a house with a Trianco TRG60 (I think) that needed a damn good clean as was chucking out sulphur fumes. Admittedly it ran ok for a few days though.
I've been clearing the flue slots out, it have managed to wedge a poker in the filth in one. Any bright ideas on dislodging it?
I've turned it off and scraped any hot coals out for now.

Carbon monoxide is a massive threat on these.

That's what I thought, so main reason for shutting it down completely before trying to clean. Can't believe it's plumbed in in the kitchen to be fair!
Think we'll end up just leaving it alone and temporarily use electric heaters where needed.One of the first things on the list is to get rid and fit an oil combi boiler instead.
