coal plus gas cook stove?

[vt-new-fp]

I have seen a range (cook stove) for sale that is dual fuel - coal and gas. It's old (c 1926). Would each fuel have to be vented separately? It would be going into a flue that currently vents propane and oil. The same chimney has a separate flue for wood with one stove in it.

I know wood hss to be on its own and I know the oil and propane together are ok. But I know nothing about coal.

Thanks!!

Coal , wood and oil can all use the same flu in Canada
EG coal/wood /oil combination furnaces
I don't know about gas
