Spring Maintenance - Keystoker 90K DV

PostBy: WNY On: Mon Apr 28, 2008 10:16 am

Well, tearing apart the Keystoker for it's spring cleaning...

After a good vacuum of the whole inside,

Removed the burn plates, WOW, a lot of fine build up under the burn plate, I know it was burning kinda funny V-Shape instead of straight across, now I know why.

Removed the Grates, vacuumed under the grates, wire brushed them good, made sure all the burn holes were clean, put back in, re-sealed the back and all the joints with hi-temp funance cement (Rutland stuff).

Removed the hopper, Removed the Stoker block, stoker motor, did a thorough cleaning, lube, cleaned the slider sections, etc...greased everything up, carefully put it all back together, plugged it in, and made sure nothing was bound up, works smooth. The nylon cam bearing and nylon screws were all in good shape. So, no burn back towards the hopper.

Just have to remove the power vent and clean it the best of i can and the disconnect the pipe and clean it.

Scraped/wire brushed the inside, need to hose it down with LPS stuff.

Almost done and ready for next year (4th year)!! :)

Next will be the LL, still burning (about 6 bags left) on idle keeping the late night chill off the house. :)

Happy summer!

I pretty much did the same with my Keystoker. That DV unit sure works nice, but it's a royal PITA to get it apart and really clean.

Also, be thankful that you don't have the "old" version stove like I do. I spent 2 hours with long brushes and a utility sink drain hose on the end of my shop vacuum hose fishing that up into the heat exchanger area to get all the fly ash out of the nether-regions of the stove. It's a great idea when it's kept clean - it really pours out the hot air, but it's a lousy design from a maintenance standpoint.

Only real way to get it completely clean is tip the stove on it's side a few times and bang on it.....

You'd be surprised what 125 psig comp air will do when sent through a flexible 1/4" air line and turned loose inside the heat exchanger! :lol:

Oooohhh, ummm, yeeeeaaaahhhh, that would NOT be a good thing. :oops:

I did think of that briefly and see if I could come up with a way to blow the ash out and suck up the dust at the same time, but that idea just had disastrous mess written all over it.

Not to mention, my audio gear sits rather close to the stove, and it's all homebrew vacuum tube gear, custom turntable, etc. and it wouldn't take kindly to a bunch of fly ash all over it.
