It actually looked like it was almost going up the chimney.
Well you wouldn’t want it in the room; now would you?
That’s fine, though you won;t get much heat from it. Pick up some smokeless fuel/coal and use that on top of some wood once the wood is well away and glowing inside. Start with just a dozen or so bits of coal, if the grate will take more, then you’re grand. The fire needs to be big enough to radiate and heat the fireplace, but not so big that the flames actually are raging up the chimney. Get a footstool and fireguard, then pull the sofa closer in and settle down…
Buy a fireguard and use, especially when you aren’t in the room.
