I have a model 403 Sedore stove measures 25”x25”x 38” high. Not sure of the new model number but this even has an Alberta serial tag on it so it’s old! The fire box is 14”deep x 23” wide ( inside) by 38” high. I’ve built a hopper 10” deep x 14” wide by 25” high. Got a good fire going let burn down and set hopper in and filled with dried wheat. Smothered the fire so unfortunately did not work? Any advise?
