Abstract From the Canadian patent

Bread oven for individual or home use. A fume vent is arranged in the roof of the oven at the opposite end from the source of heat so that the hot gases contact the roof to heat it. A by-pass passage is provided which can be, unblocked by one position of the ash pan to produce a counter-draft and thus slow down the rate of heat production. The ash pan can also be positioned so that the by-pass passage vents fumes from cinders or embers in it.
