Replacing the side bricks, rear baffle, top baffle and air tube:
P300
Open the door fully and look up inside the fire box.
You will see the air tube and baffle above the firebox chamber, and two side bricks and a
cast iron rear baffle.
You will need to remove the two side bricks in the firebox before being able to remove the
air tube and baffle.
To remove the side bricks:
At the front bottom corner of each side brick there are holding plates that clamp the
corner of the brick. Remove these screws and take out the plates.
The side bricks can then be pulled out by lifting slightly to clear the bottom retainers and
rotating the bottom edges towards the middle of the firebox, and then pulling forward and
out the door.
