It was pretty much identical to this one: https://www.grainger.com/product/21EW92?ef_id=Cj0 ... lsrc=aw.ds
Although Keystoker told me it had been 'modified/designed' specifically for their stokers. I'm pretty sure it had an extra jumper wire between terminals...anyway what they sold it for and what it was on ebay was pretty embarrassing differential wise, my honeywell is a R883B5, it was so dusty when I initally pulled it to use I felt like Indiana Jones blowing all the dust off a relic.

I've been using the timer listed in the link in my signature below. It's been working nonstop on my kaa-4 for 2.5 years without any issues. One of the best changes made to my system.

Oh nice!! So I assume the timer resets so that it doesn't try to keep fire right after a combustion call from the aquastat? Sorry for the rookie questions lol

No, this setup just runs 43s every 10 minutes as it's configured. You could probably wire another in series to force a power reset at the end of each heat call, but with my flat bed stoker that is really not needed.

I have a timer that runs one minute an hour. During the cold months, and extra minute is just used up as heat. In the shoulder months I have never had an outfire. I have had some scary hot temps on occasion, ( 240 and a bit above) but have never tripped the safety valve. ( maybe my temp gauge isn't 100% accurate)

I think 1 min per hr is what AA recommends?Freddy wrote: ↑Sun. Dec. 05, 2021 9:06 pmI have a timer that runs one minute an hour. During the cold months, and extra minute is just used up as heat.

I have gone over two days in the shoulder months and turned the boiler back on and it’s came back to life, I have 0 draft at idle, and go positive draft until the secondaries light in the boiler.. maybes it’s possible your fire isn’t fully established, one fall i lit, and about a month after we had a warm spell and I lost fire once, and I contributed it to not getting fully lit at first, it’s the only time I’ve lost fire in 4 years..

One with an ashed up fire and no draft.hotblast1357 wrote: ↑Mon. Dec. 06, 2021 12:44 pmYes, but 4 hours vs 48 hours doesn’t seem right, he should be good for at least 12-24 hours, it is basically a hand fed, what hand fed doesn’t last more than 4 hours?

I don’t think he has a drafting problem? And how does a axeman get ashed up? It’s constantly being ashed when it fires, unlike a actual hand fed that only gets shaken say every 12-24 hours.
Lee, Also something else to think about.. how long does your boiler go without “firing” during a Normal day, say between 8am and 4pm with OAT say 50 degrees, when no one is home and only heat calls are goin? I’ve seen mine go all day without the combustion fan coming on, at least 8 hours, I used to run a timer on the combustion fan..

Yeah I agree that the bigger fire pot on the 260 likely is a factor. It has more coal a further distance from the walls of the boiler so I would think there is a better preservation of heat in the center. I've watched mine come back after being off for 4-5 hours and it takes a real long time to revive the fire, like up to 20 minutes before I start to see any progress in the boiler water temp. We know that all coal isn't created equal, so there's that variable too. I'm using the Mammoth Vein coal from Jeddo.. Maybe its not so forgiving.
At max 5-6 hours.. any longer and it most likely won't keep the fire.hotblast1357 wrote: ↑Mon. Dec. 06, 2021 1:26 pmhow long does your boiler go without “firing” during a Normal day, say between 8am and 4pm with OAT say 50 degrees,
But it seems to go in hand with the draft loss..

I dunno.. that's hard to think that after a month it couldn't straighten itself out..hotblast1357 wrote: ↑Mon.
