Hi Everyone an fellow Jotul owners .
I recently 2025 fall purchased a 2nd. Jotul F500 wood stove for my home which is a replacement of a former 2014 era Oslo f500 stove . The Jotul stove has been a excellent all around stove for myself heating my home in New England . My stove for the most part is utilized starting the Fall and runs /operates till maybe 1st. week of April pretty much non-stop either than for cleaning / dumping ash or I give it a break and don't burn /use it for a day or two. I burn mostly oak ,maple, ash and some small other clean type firewood and yes its seasoned covered approx a year or two.

My question an concerns on this Oslo F500 V3 is it seems to burn up eat a little bit more wood than my older 2014 oslo . Yes I monitor the catalyst probe on the side of stove keeping it within the mfg. reccomended temps. I do / can see the interior manifold is bright red glowing and operable at the temps noted .

My gaskets appear to be in good shape with no leaks as I tested them and also smoke tested the stove passing both tests.
At times I have to basically choke the stove off to have a long burn which i find kind of dumb to do to get a long burn into the nite.

Yes I have read about the 2 ports located underneath stove whisch houses the ashbox . On my stove the ports were sealed with some type of sealant which is still there.

I also had found on both sides of the lower ashbox heat shield , what looked like rubber type colored yellow plugs which I removed and assumed they were from the 2 ports everybody talks about of air leakage .
Yes I did buy magnets , but the ports have the sealant in the holes rendering using the magnets useless.
Being this was a New purchase 2025 , I did have the dealer come back housecall an check it. They said it was fine , my chimmney height c/o the stainless liner to exit was perfect and the gaskets good . Dealer stated that this F500 acts operates a lot more different than my other 2014 Jotul .

So bottom line what other areas might I check also on this Oslo V3 ? Just seems to eat up more wood , maybe it's just me over thinking this newer f500 compared to my older f500.

Thankyou for your input / oppinions .

Well it’s a new design and they could have tweaked the combustion air many different ways to achieve the cleanest most efficient burn they were shooting for.

Do you monitor flue temps? Maybe this stove lets in more air and you need to shut it down sooner? Maybe a pipe damper would help? Can you shut it down to a black firebox cat burn or does it always have flames?
