To connect a woodburning stove to the main chimney flue? This old house has 12-foot ceilings, big windows and a gas furnace. So it's either that or sweaters all winter.

Check your local code. In at least some areas, it is not allowable to have multiple connections to a single flue - each source should have its own.

If the gas furnace flu is all you have, you'll need a new stack for the woodstove in any event and the gas flu is likely to be way too small and neither insulated nor fireproofed in the way a stack from a wood flame needs to be.

If you've a fireplace, then there are no insurmountable problems to getting the wood stove connected to that chimney.

When we bought our house, it had a wood furnace sitting beside an oil furnace, and the seperate stovepipes exhausted into a single-flue chimney. Our insurance company almost had conniption-fits.

We replaced the chimney with a stainless-steel Selkirk-type modular chimmey (single flue) and the furnaces with a UL-approved wood / oil combination furnace that has separate fireboxes for wood and oil that exhaust through a common pipe. The insurance company is happy with this.

Apparently, it is not important that there is two exhausts into a single flue, but where they join... ;)

A lot of old fireplaces were back to back and each flue joined into one outlet.

One advantage of a separate SS flue is the radiated heat from the exposed part of the chimney reduces the amount of heat lost.

id be asking if it is safe rather than legality
