Surprise at Cleanout

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

I turned the Keystoker 90 down to an idle today. Removed the baro vacuumed the pipe from the stove top and inside the masonry thimble. Got brave and stuck the hose up the 2 exhaust pipes running from the bottom of the stove to the stack. No melted vacuum hoses, all is well. Cleaned the hose out with garden hose and stored it away, the shop vac sits outside under plastic bag for a couple of days to make sure it does not burst into flames and then out to the shed it goes.

This post series reminded me to do my interim 3-4 minute quickie clean just like above except I snake a (bent at end) ~32" vent brush from the removed boro down toward the fire chamber. This removed any heavy ash from the elbow. Do a quickie vac same areas as Sierra did, minimize CO in the room.

Then put stove on low heat, medical mask (Stove Doctor, eh?) and gloves on, remove ash pan and open both doors, snake and rotate same vent brush up both back wall tubes. This takes 30-40 seconds, close everything back up.

Can see how a bottom vent accumulates more ash, need to clean more often, also good comment that cleaning should be by lbs, not time.

Good posts here for an extended burn season like we are currently having.

after such a long cold winter I never did shut my channing III down for a cleaning
mid season, so after reading this I layed in bed friday nite thinking, and guess what I did
saturday? pulled my pipe off the back, but I have to say it was much less than
i had expected. maybe 1/2" in the pipe.. quick vaccuum of the pipe and inside
the back of the direct vent fan, then blow up and out from the bottom and put it
back together, and relit the stove. good for the rest of the season, which looks like
it is never going to end!!!!
currently running a Channing III in our basement,
feeding into cold air return and circulated with
forced air furnace.
love the even warm heat!

Did you change coal suppliers or notice a chance in the coal characteristics? Some coal produces more fly ash than other coal.
You beat me to it. It kind of makes a "dirt leg" and gives the fly ash a safe place to accumulate.
Now thank god for the media, for saving the day,
