My electric oven is built into an island countertop and it HAS NO ventilation! I am constantly wiping up the film that is left every time I cook (not to mention whatever we're breating in:Z). We can't vent up because it is a cathedral ceiling. There is only a 3 3/4" space above the stove edge before the counter top of the bar behind. What are my options? Do they make tiny enough fans? I've seen the "downdraft" vents that are for countertop ranges but nothing for my flat topped stove!!?
