Multifuel Airflow DownDraft problem

[Airflow]

Hi All,

We had a stove installed where we live and have been having problems all winter with it.

We have 2 different stoves, a 6kW one, and this 10kW.

We use the same fuel in both of them - coal and wood - and have had smoke billowing out of the new stove ever since it's installation.

I've put a video together showing the stove, where it's installed and what's been going on with it.

WOuld appreciate some insight that anyone could give on what could be causing this smoke.

What does the top of the vent run look like and how long has it been since the entire vertical vent run been cleaned.

You also need to do something about that "concrete" piece that is cracked as that crack is going to be part (maybe all) of your problem. It lets house air enter the vent run from outside of the stove's airflow system causing a partial loss of draft in the stove. All vent runs must be gas tight unless a barometric damper is called for in the installation instructions.

I agree with Smokey that the main problem for you is the concrete piece that is cracked but the transition from concrete to chimney may not be sealed as well. You will have to find pipe that will transition from the pipe coming off the back of the stove to make that connection to your chimney. It appears the piece may have been damaged during installation of the new stove. Who did the installation?

Not sure what fire and building codes you have in Ireland but this website will give you an idea of flue pipe needed (I know it is a ways from Dublin but thought the visual would help).

I would not use that stove until you get the exhaust/chimney sorted out. Do you have a carbon monoxide detector?

Smoky is right , the leaking in the flue system inside that box is the largest part of your issue , the flue gasses are not being pulled hard enough to the rear to prevent smoke coming into the house, a bit of negative pressure (natural in most any structure) does the rest. flue systems must be airtight to prevent los of combustion airflow through the stove.

Lake Girl raises a great point as well, CO detectors are lifesavers! we know we are dealing with draft issues and coal produces more CO than wood due to its chemical makeup. combining a problematic flue system and coal can be a deadly combination, you REALLY need to get a professional out to remedy the issue as soon as can be done , and if the other stove is working fine , rely on it alone until you can get this sorted out.
