Overfiring Englander

,.. so Ive been running GS's,. (a very consistent pellet),.. and trying some others here and there,.. all while leaving the stove on relatively the same settings,..2-3,.. lower buttons 3-3-1,.. then last night I grabbed a bag of Somersets,.. (by accident,. cause I been hording them for the colder weather),.. dumped em in the hopper,.. and the stove tripped the high heat shutdown three times over the course of the night,.. after repeated attempts to turn stove down,.. 1-1,... 1-1-1,.. it would still run up over 500 degrees and trip the sensor.

This morning I unpugged the stove for 10 mins,.. and did a restart,.. added GS and now shes fine.

Any ideas

Raise the blower setting. Get some of the heat out? Heat on 1 blower on 3,4,5,etc..

Check the convection blower for dust bunnies and stray fuzzy animals.

Also our good friend ash in the works can lead to heat buildup in the heat exchanger and elsewhere, yeah I hear you, my stove no have any ash anywhere.

what Dexter said

Yeah, the blower set on #1 is probably too low. It`s only 145 cfm at top speed and on #1 it isn`t going to be extracting much heat especially if from the stove is running on a low setting.
I can understand you would want less heat on a warmer day but a compromise/allowance has to be made with this stove since it doesn`t have an auto on/off capability.

Yup just as I expected, you have defective Somersets. I'll take them off your hands and use them for something like um....bunny bedding..

(i don't have a bunny)

These guys know what they are talking about, i would go with what Dexter said. Makes sense, too hot, get rid of some of it out the flue.

i have seen someone return somersets for exactly that same reason, said to hot for their stove kept shutting off

Did you buy dem dere defective pellets???

raise the LBA back up to at least 4, you are runing too little combustion air through the unit the slower the exhaust runs through the stove the hotter the unit gets internally also makes for a quite dirty burn altogether.

Yep, what he said.

Shaw520 · Dec 19, 2012

Thanx! ,.. dam this place is the best,... so Convection and LBA turned up?,... makes sense.

Yes.
As for the convection air setting, it should follow the heat setting. If you set the heat at 4, the blower setting should automatically follow.

I have wondered about this. Why wouldn't it be better to set the convection at the highest speed that can be tolerated in terms of air noise. It seems to me that the more air, the more heat extracted from the stove. I know that the air temperature will be lower, but the total heat moved should be greater and therefore the efficiency should be better. Is there a flaw in my reasoning?
In my workshop I run my PDCV at heat range = 5, convection blower = 9 because I can't hear the stove over the dust collector and table saw etc. Is there an advantage to slowing down the convection blower?

There has been many discussions on this. It's either a LOT of lower temp air (high fan setting), or less of hotter air (low fan). Sort of "six of one, 1/2 dozen of another" kind of thing.

oh that stuff?,.. yep its getting up there,.. havnt cleaned in two weeks.

Yep it can also cause high temperature issues because it slows down the air flow through the combustion air system exactly like turning the burn air down, it also screws up the burn the same way as well.

Get enough of it in there and in the correct spot the thermocouple doesn't see it and all sorts of things can take place.

I think there a point at which,.. if the firebox isnt creating enough heat,.. then your convection blower is cooling the air to the point of being insufficient... something like that.

That is why a good number of us preach about cleaning the stoves regularly and completely and to never, ever, burn a stove with its safeties disabled except for a quick test to rule out things.

Frequently what saves your bacon will be the fact that one safety will catch what another doesn't and a lot of catastrophic issues are caused by multiple failures with a safety being one of the things that failed.

Absolutely,.. very good info..
