Load up enough scrap wood to get the fire way up out of the top. That should get the rest of the paint off. If there is any left you should be able to get the little bit that is left off with a wire brush.
I would not paint over any that is left as it will cause your high temp paint to peel off.
Best of luck... you will be rewarded for your efforts.
