Question for Keystoker Draft Experts

PostBy: jrn8265 On: Tue Sep 25, 2012 8:18 am

I have a koker.

In the past when it is warm outside I can have the draft fall to .005 or nothing at all even with a 275 degree fire in it, then the CO starts.

I notice in the new Keystoker manual it says if the draft is below .02 then close the Combustion blower shutter.

I have not tried this closing of the shutter at all and it is at factory setting of 1/2 closed. Has anyone changed this? Does it increase draft that much?

Thinking this could be my solution for riding out warm days without having to turn the stove off.

Appreciate your insights and thanks!

I have a Koker but it's direct vent so I've never adjusted the combustion intake. I use a rheostat to adjust the speed of the draft motor.
It seems to me what Keystoker is saying is when your draft gets down to .02 the combustion motor is putting more air into the furnace than the draft can pull out. The difference between the two ends up leaking out of the furnace as CO. So closing down the combustion motor opening will reduce the air being pushed in to something the draft can handle. So by doing this you're not increasing your draft, you're reducing your combustion, which will result in more unburned coal or maybe even having the fire go out. But it will also reduce the chance of putting CO into your house.
That's what I think their instructions are based on.

CoaLen hit the nail on the head. During warm periods you have to limit the air being forced into the fire box so the lower chimney draft can keep up with it. When it is sub zero in Jan-Feb, let er rip!!! Chimney's draft should be able to pull a lot more air out of the stove.

Well, last night I moved the shutter from 1/2 closed position to 2/3rds closed position. Looking forward to firing her up later this month and seeing if it makes a difference with co on a warm day. Thanks all!

I am interested in a keystoker boiler. am I reading right that some of the models require a 14" and 12"chimney? I have only a 8"and upgrading the chimney would be not possible.

The ones you are looking at are HUGE BTU outputs. Is this for you house?

The KAA2 is only a 6"outlet @ 76K BTU
The KA6 is 8" outlet @ 122K BTU
The KB8 is 9" outlet @ 163K BTU

Depending on what you need, the larger the boilers, the larger the outlets.
