In my house i have a cast iron insert fireplace that has been fitted in place of the original 1920's fireplace. The work was done before we bought the house.
The chimney has been recently swept but is very, very tall. The roof is already steeply pitched and the chimney protrudes through the edge of the roof and then rises above the ridgeline.
When the fire is intially lit the draw is very poor and smoke comes out of the fireplace into the room. Once the fire starts to take hold and the heat starts to rise up the chimney the chimney then draws very well.
The smoke coming out of the fireplace on iniital lighting is a problem though as its discolouring the paint above it.
I had the chance to stick my head up the fireplace today and there is the remains of the old throat a couple of inches above the insert. There is a damper/flap that comes off the top of the insert that kind of shields the old throat, but will the old throat he affecting the draw?
What sort of throat, if any, should there be above this sort of fireplace?
Thanks in advance.
