Osburn 7000

Here you go...a bit crude but works

 

Cool, Thank you all. I hadn't noticed these responses. Driving the wifey, plowing the 1o inches of snow plus 2 inches of rain/sleet turned ice. Clearing the crap off the greenhouse etc. My apologies!

My parts were to be delivered yesterday, I got an Email from UPS saying due to the weather it would be delayed. I got another one this morning, so I'm guessing tomorrow?

I did clean the beast yesterday and started my first bag of stove chow. Still fussing with the settings. I did notice that there are more fines than the LG's. They do burn hotter than the Maeders however I have my settings causing the bag to be consumed in 19 hours. I believe the ratio is correct so I will back all settings down a notch etc until we find a happy setting. I haven't figured out what they're made with. The bag says white wood?

 

It's believed these are the same pellet as Energex hardwoods...so the Chow's are some type of hardwood/hardwood blend

 

Mine is 5 up and 5 out. I'm still working the settings back for the stove chow keeping the same burn ratio. I believe I'm now at -2 combustion/0 Auger/ and 0 exhaust. I'll turn it down another notch this morning after we get the temps up here -2*

Yesterday they did deliver my parts. The auger is a different design, and is now cast iron. The important thing is that there wasn't an auger support gasket included. I'll be calling the factory again today.

 

SBI is shipping out a gasket. He said it was possible that you could recover it, but it would have been appropriate to send a new gasket. I expressed my pleasure with his position. It's rightly under warranty that includes labor. If I'm doing the repair I want it right so there's no question if it fails again.

 

Added to the regular maintenance includes blowing out both augers and shooting some graphite in the tubes. The replacement parts worked well last year.

The device goes off line too many times this year due to high winds, crazy winds in fact. Two things we've realized that no matter the configuration at the termination cap we can't beat the back pressure knocking the stove off line. I jump up the exhaust fan for the duration of the wind storm, but most gusty days 30 MPH and up cause too many conniptions. The OAK contributes to this back pressure issue also.

Another thing learned was the OAK bringing in 5 degree temps or colder to the burn pot while the stove set on the lowest burn rate will cause a "no fire detected" temp warning, which shuts down the stove. If the exhaust fan is kicked up it happens even faster.

If the layout of the house would have allowed it, installation on the east and north side of the house we would've been better off.

 

The things we do to keep it operational, if it works

 

Have you considered wrapping the cap with close mesh screening, to act as a windbreak?

We had to do that to the chimney cap here to stabilize venting draft in high winds, when we first started w/ the pellet stove.

 

Yes we did the mesh last year and it didn't make a difference. I heard the wind laughing at us from the stove. This year I had a multi directional and layered termination cap to see if that would work...
NOT.
We have 1/2 a mile of open fields in every direction. The predominate winds are from the Southwest. the winds get a boost from the three lakes in that direction.

There was no other option for placement of the stove within the house. We have no snow coverage, and another warm winter so far. Far more winds than normal. Im resolved to just deal with it.

It runs great as long as there are no high winds.

 

We're using 1/4" wire mesh fireplace screen, double-wrapped to 1/8" around the chimney cap, but that only works to about 35 mph or so here.

But that's on a horizontal vent / top of chimney, and not pointing directly into the wind either.. Much different than your venting.

I'm considering replacing it w/ 1/8" mesh hardware cloth, double-wrapped to 1/16" at the end of the season.. Dunno if that's going to be too restrictive though, will need to do some testing, before installing.

Every other windscreen solution I've seen is vinyl or plastic, wouldn't work here. But if you really needed to, a windscreen alcove, far enough away from the house / high enough to deflect wind may be an option for you there.

 

Well the other day the stove began to act as if there was heavy winds? But there weren't??? SO I shut it down and did another cleaning. I had just done one a week ago. With the cleaning done I started it back up. Immediately it errored out, with a blockage/pressure switch error. Less than two months ago I had stripped everything down and had done a complete and through service, which included cleaning the vent pipes and replacing the original termination cap. Deduct the amount of time we had to shut this down due to high winds and we're talking about maybe a months worth of use. So with that error I reamed out the orifice on the silly little connection for the vacuum hose on the back side of the exhaust blower. BTW the dumbest place to put it....poor poor design. Tried to start it again...again the error came up? So, I got the leaf blower out, set up outside after disconnecting the vacuum hose on the pressure switch and looked up at the grid work on the termination cap and was surprised to see that there was the blockage. It was substantially blocked? WTF I broke up the chunks and hooked up the leaf blower, very little dust came out. So the exhaust fan had sent it all to the termination cap.


Of note: While hooking up the pressure switch hose I found another design flaw. The air vents on the rear panel are razor sharp and cut my fingers as I placed the hose back on the switch.


I don't understand how this got blocked up so fast. I suspect that the attempt to counteract the high wind pressure with adding to the exhaust pressure the max of 10% didn't work. All I managed, was to move particulate matter up and over the vent pipe only to be met with the high pressure of the winds and then deposited. That said the LG pellets are burning differently this year? My settings for the last two years aren't working. The spent fuel is seemingly thicker in the ash pan, and yet more fine dust is moving up the stack? Does this make sense?



BTW, I know adding the 1/4 inch mesh wold have been an issue. When the grate on the end of the termination cap is about 1/2 an inch, and it got clogged.

 

Would you please post a picture of the venting where it is terminated and if you are running an OAK add one of the OAK's termination as well.

 

Glad you got the blockage cleared Ambient, you must have crazy wind there in that spot. ..

Thanks for posting about the windscreen feedback, I'll have to do some more serious testing before thinking about going any more restrictive on the screening.

re: LGs burning different - only thing I've noticed so far (this year's batch) on the Satisfaction branded pellets is they are consistently longer ( 3/4 - 1" ) vs. last year's batch, and many more longer vs. shorter pellets in the bag.. Everything else is the same here, same temps. / ash level / etc. IOW, doesn't seem like the mix / wood species used have changed to any great degree.

x2 - if you would, post a pic. : STB, imacman, & many others here were invaluable in getting us up-and-running when we started w/ their posts & sage advice, lots of smart folks here have been roasting much longer than you or I .. maybe they can help.

 

Sorry too many irons in the fire.

Two errors of late....both when the stove was running on low, three bars, I got a low temperature no fire detected in the pot warning. I assume this fresh air vent is causing the burn chamber to be too cold.
