Chimney too short?

What is your existing chimney?

try running the stove with 12.5ft of chimney before extending it. you might be pleasantly surprised with the results.

These would be the best solution...but too far out of my price range.

I had the same problem and got the tall extendaflue and am more than pleased with it. I do not know how to post pictures or I would.

The thing is solid and attractive - I did have cement added around the base as per instruction.

We just experienced an 'almost' tornado here (A storm one step away from a tornado.). Trees down. Power out for 2 days. Windows, fences you name it.... broken - blown over. Extensive hail damage. My extendaflue is still standing and doesn't have a scratch on it.

My advice is if you can't afford one of these - find a way to work something out even if you pay 5.00 a month for the rest of your life. :lol:

I would try this but I don't want the inspector to read the installation manual and not give me the thumbs up because of the discrepancy.

Do inspectors usually check for things like this?

Don't know if the inspector will check........good point though. Experts should chime in shortly.

Do you know if I can add it later? I will just buy a regular liner kit now and if I have have poor draft, install an extendaflue? I don't have a terracotta flue that I can attach to. My flue is flush with the top of my chimney.

I did add mine later. Insert was installed in Jan. and extendaflue was installed in July. I did not have to have an inspection so chimney height not an issue. It was short and I did want to add height so I went ahead and installed the flue.

I can't tell if it made a huge difference in draft but I do know that it cut down on dust,ash etc.. that got sucked into our other fireplace chimney when both chimneys were the same height. No more fine coating of white dust in our livingroom or smoke smell - which would happen on occasion depending on the wind.

This comes with metal supports that can be attached down into your chimney if no flue is available to attach it to. I think it can be attached to a flush chimney but you better check with the Webmaster to be sure or check out the the install instructions on it's web site.

If you install one later you will just have to get a few feet more liner to add to existing liner. You might want to see if you get a better deal when you initially buy liner and get what you will need then rather than purchasing just 3 feet later.

By the way - I had a smaller insert with a 1.7 cu.ft. firebox before my Jotul and it had no problems with draft. ( My Jotul has a 3 cu.ft. firebox)

I'm interested in these as well - only to appease the smoke complaining neighbors mentioned in my thread.

They INSIST that the issue is exacerbated by the fact that we have a two story chimney adjacent to a single story roof (attached garage with den behind) for 24ft, then the two story portion of the house.

According to code -chimney is just fine - the requirement is something like 2ft above anything within 10ft radius of the chimney - this is for making sure you don't catch your house on fire with ashes - not for good fire draft or smoke dispersion...

We have three chimney's next to eachother - the middle one is the wood stove - the other two? we have no idea what they are there for - I think the house was set up to have an addition put on over the garage / den and these might have been added for the possibility of putting a fireplace in the upstairs room? who knows. The old fireplace had a "heatilator" in it, not sure if these flues would have anything to do with that - but they are sealed off up top....

Any ideas on flue extensions or particular flue caps that will keep smoke going "up" instead of "sideways"???

Sorry to thread hijack - but I'm guessing answers to my questions will be educational for the OP too.

If you line the masonry chimney with DURALINER, I believe you can extend it up to 3' or 4' above the existing flue without bracing....IIRC....

Correct...once you get to 5 feet you'd need the guide on support.
