Question about O A K.

[TWilk117]

Good day folks.

I’m curious about outside air kits and how they function.

Specifically if you’re running an OAK, on let’s just say a Jøtul F 602, does the front air adjuster still work?

I’m confused.

Yes

 

[TWilk117]

Thank you.

Is the outside air controlled or limited somehow?

Every stove is a little different but generally they direct the outside air supply to the intake for the stove, most are not 100% air tight.

An oak is an outside air connection, aka direct path from the outdoors to your stoves primary air inlet. Some stoves offer a kit which will allow a direct attachment of 3" metal piping. A oak will only provide a different source of air, it should not affect the stoves control.

 

[TWilk117]

Oh okay, that makes sense, sort of.

 

[TWilk117]

But what about the more simpler stoves that have a grate or a knob that opens up to the room?

Thanks for replying.

As far as I know, or think, Stoves can’t be 100% shut down because they wouldn’t meet EPA regulations.

Some stoves like the F602 do not have an OAK option. The best one can do is have an outside air supply metal duct that delivers outside air close to the spin draft wheel air control. You could put a valve on this duct so that it could be closed off when the stove is not burning.

The F602 is not an EPA stove. The F602CB is, but it still has no outside air option. This is one of the reasons why it is not permitted for use in a mobile home.

It lets the stove get air from outside instead of inside.

This is good for safety: Some houses are so tight that outside air can't infiltrate the house fast enough to keep up with the stove; this is unpleasant and/or dangerous when combined with other depressurizers (clothes dryer, bathroom fan, range hood, etc.)

Leakier houses get plenty of air infiltration, but an OAK still makes the house warmer and more humid if not safer. Cold dry outside air is drawn through the OAK, through the stove, and up the flue. Without the OAK, cold dry air is drawn through the leaky window in the back bedroom (and every other crack in the house). Warm air from the stove room is pulled into the stove and up the flue.

You do want to ensure that the outside air comes in from below the stove; especially if you have a basement stove, confer with your stove manufacturer to make sure it's installed safely. You do not want the stove venting red hot exhaust through your OAK.

So, just like the wood stove itself, it is probably a good idea, but you need to make sure it is installed correctly.

They have something called the fresh air kit available for the new 602 and new 118.
I suppose this is something different?

Sounds cool. Thank you.

As of last fall this is not in the F602CB manual. I see that marketing has put this on their website under popular options but I find no part number except for other Jotul models. Have you seen the kit or talked with a dealer about getting one?

 

[begreen]

OK, with some deep digging and no help from Jotul I found the adapter. It just puts outside air near the stove. The kit hangs on the rear heatshield and works as I described with a simple valve to close it off when not needed. (Thanks WoodsmanPP!)

Found this with google.

I haven’t talked to any dealers. I can not realistically buy one right now.

Oh okay that explains it better.
