The pic of the stove, makes the stove flue look like 6", and like it goes into a larger flue/crock then 6".

Are you sure its not a blockage in the stove itself.

That's what I'm wondering about -- perhaps a broken lever or something. My stove will fill the house with smoke if I (or my wife...) builds a fire without opening the bypass.

Given the dimensions of the exterior chimney and the shape of the cap, it might be Selkirk triple wall pipe (incorporating both mineral wool and an air space). That's a good piece of material -- given that you had a chimney sweep look it over, I think you can rule out anything outside the house as the source of the problem.

Did the sweep disconnect and inspect the stovepipe inside the house?

How would I check the stove for a blockage?

And if the stove had a blockage wouldn't that stop the down draft as well? Meaning I wouldn't feel any draft?

A blockage would restrict flow, but not stop it. It could restrict it enough that the heat doesn't draw up enough to prevent teh fire from heating up the chimney enough.

ONCE YOU GET THE FIRE BURNING DOES THE SMOKE STOP COMING OUT OF THE STOVE.

IS THERE A DAMPER ANYWHERE IN THE STOVE? iF YES MAKE SURE IT WORKS AND VISUALLY SEE IF IT IS OPEN.

IF YOU GET SMOKE IT SHOULD JUST BE FOR A SHORT TIME THEN IT SHOULD CLEAR AND YOU SHOULD SEE A GOOD FLAME IN THE WINDOW.

CHECK THE GASKETS AROUND THE DOOR AND LOWER DAMPER, MAKE SURE THEY SEAL TIGHT WHEN THE DOOR LOCKS SHUT.

The smoke never stops coming out. I've had to put the fire out as ALL the smoke comes in.

Are there fire bricks inside the stove?
Can you take a mirror and look up the flue?
When you look inside the stove can you see the flue entrance?
If there are fire bricks inside maybe one is broken or loose and has fallen to partially block the flue exit. I knew someone who was transporting a stove similiar to yours and when he set the stove , looked inside and a fire brick had fallen out and was laying in the bottom.
What condition is the inside liner?
Did you buy the stove new?
I know you don't want to spend a lot of time running around while it is smoking but maybe you could have someone look to see if smoke is exiting the top cap.

Down draft issues - woodstove


With a flue system it is ideal to not have too much length above the roof as the flue will take longer to warm up. Pockets of cold air in addition to the heavy cold air above it are significant factors in causing back pressure. A flue should be as straight as possible and also best to have as little joins or extensions as possible. The exhaust should be expelled with as little obstacle as possible. I am involved with a chimney cowl in New Zealand called a FlueCube, conceived/ invented by electrical engineer Neville D'Herville. It has no electric or moving parts and is effective by due to its shape. I can only say that it may be worth reading about. The testimonials from those who have it installed are encouraging towards the atmospheric problem of down draft. Rather than trying to compete with the heavy cold air it integrates it into how it functions, compressing and combusting unburnt particles, allows a steady vacuum inside the flue, easier light-up, faster to get the appliance radiating at optimum heat and no more smoke inside the room. It's current maximum size is designed to fit a 150mm/ 6 inch flue. Smaller sizes are available but larger ones are still in the trial stage.

Make sure all appliances that exhaust air are off, and try using the wood stove again.

If your attic access is from inside the house, make sure its sealed and not drafting warm air out of your house.

Sorry I've been away for a bit..,

Ok, take a look of the pic I added...

IVE GOT UP DRAFT!!!

The weather today was sunny and about 9 degrees (Celsius) The chimney was in full sunshine.

It looks like the outside temp is going to be my issue??

I am going to call a local pro to come and assess my set up and see what he recommends.

Go back and read post #5 & #6 if an expert doesn't arrive at the same conclusion I would be surprised.
