Hand Fed Coal Furnace: Yukon - Husky
Coal Size/Type: Anthracite
Other Heating: Oil/Wood
Location: Youngstown OH Area

So I recently bought a Yukon husky wood oil coal furnace. Due to not being able to add a chimney and the oil burner dying I felt this was the best option. The furnace is rated at 112,000 btus. I noticed today that the chimney that this would connect to is smaller than the one for the fireplace. I did add a 6" SS liner to the fireplace chimney due to tile issues.

The one my new furnace Connects to is 6 3/4 x 11. I was going to add a liner but I believe it needs an 8" which obviously won't fit. So am I in trouble here?

Every bit of this is going to depend on your
chimneys height as the stack height is going to
create the pressure gradient to allow proper
combustion in your firebox.

The only way to really check is use a good
draft guage when you are hand firing it and
making sure you follow Yukons recommendations
for installation as you may end up needing a chimney
top draft inducer.

You may just need a chimney pot/chimney extension
that screws to the chimney collar/raincap.

I have a chimney extension from Rockford Chimney
Supply and I was very happey with the quality of
the work done to manufacture it. It also came to
the house undamaged from shipping it so the
packaging of it prior to shipment was done well
with double boxing it.

The chimney extension comes with a mounting
base that is screwed into place using tap cons and
the extension is bolted into place using a hinge to
allow for chimney cleaning.

Furnace is in the basement of my ranch. I would guess the chimney is at least 26 - 28 foot as it take 20 foot of rod to clean the fireplace flue on the first floor. So really I won't know till I hook it up.

Draft inducers are not $2000 and you should not need one.

A chimney liner is something to be avoided if possible, so look real hard at the present liner to see if it might do or can be repaired.

Your stove has a large flue outlet because it is rated for wood. Wood has a large rush of gas and smoke when first heated so needs that capacity. Coal does not do that and 6 inch should handle 112,000 BTU easily and you most likely will never burn at that rate anyway.

Just feel your way with wood and if it backs up just load smaller loads at a time or do it in two steps spaced 30 min. apart. Avoid long slow burns that create creosote. The Yukon might be EPA approved which means cleaner burns with wood.

Ironically my wood burning fireplace is 6" and the firebox is about the same size as the husky.

Shouldn't need anything. Check draft by lighting a piece of newspaper in the cleanout. Ifn it sounds like a jet engine , & sucks up the paper you are good to go. Shouldn't need anything else. With a chimney that tall you will be fine.

So tile should also be able to handle the combination of burning wood and coal?
