Feeling the Heat
Jan 15, 2008

Hartland,Me.
my neighbors(and best friends) have an englander 25 pdvc...since the beginning of the heating season, the stove has been driving them out of the house it was so hot. after running for an hr. on feed rate 1 blower speed 9 , the house would 84-86 deg. and they would shut the stove down, and let the furnace take over.

after searching thru all the posts, i found the one gio posted about the a,b,c,d modes. i went over for coffee last week, and the wife was getting ready to start the stove. i asked her to wait, and let me check the mode...it was on "C" mode. i changed the mode to "D" with a setting on the three buttons of 6-4-1, feed rate at 1 and blower speed at 9. i thought "great, we got it" it only lasted for a day, and the heat was out of site again.

friday nite i went down to my dads. he has the same stove, and it runs beautifully. so , i wrote down his three button setting of 4-4-1,and tried that with the same feedrate and blower speed....again, driving them out @ 80+ deg.

this bugged me all weekend, as they are constantly shutting the stove off, because its too hot. tonite, i went over and said to make a big pot of coffee, i'm going to be here for a while...lol. when i started with the stove, it was "d" mode 4-4-1, feed 1 blower 9. 82 deg.

i brought the first of the 3 buttons down to 3 (3-4-1) and let it go for about 20 mins, i watched the burn pot and saw that the feed of pellets slowed a tiny bit. house was still running 80-81 deg.

this time i went down to 2-4-1 not touching feed rate or blower speed. waited again for 20 mins. check t-stat in living room...80 deg. arrrgh!!!!! i said if i turn it down anymore, its going to go out from lack of pellets. then i looked at the buttons again. all this time, i never changed the third (air on temp) button. hmmmm....i bumped that up to 2-4-2 and waited a bit...hubby called from the living room, saying i was onto something...79 deg! wooohooo...progress!

i went at it one more time and bumped the third button to 2-4-3, feed rate 1 and blower speed 9, waited 20 mins again...hubby says stop right there, 77 deg and comfy... the burn looked real good, nice and strong, plenty of pellets, and not to much air. i wrote those settings down and taped to the back of the stove...i think (hope) i finally found the sweet spot. with the feed rate at 1, it gives them room to bump up the feed rate if they need to.
 
That's what you call perseverance. Be ready for some more coffee and 'seat time' when they change pellets because nothing ever stays constant. :lol:

heard that! they are pretty partial to Cubex and have burned them all winter. but i know what your saying. thanx.

Total length of time during adjustments?

I think you're getting "results" that don't have anything to do with the AOT setting. You made changes to the stove lower buttons, but may not have waited long enough for the changes to take place.....they don't happen in 10 or 15 minutes, especially in a room that was already heat-soaked.

From what I know about the Englander control panel, the AOT is just a setting telling the convection fan when to turn on based on a set temp when the stove is first started.....I don't think it has any effect on normal continued burning. It should always be on 1.


If I'm wrong on this, I'm hoping Mike Holton will see this and correct me.
 
what he ^ said X2. Got to wait hours for real results.
 
I have been burning Pro Pellets and had a small clinker problem and kept cleaning cleaning cleaning thinking it was an air issue. I opened the feed door open a touch more before filling with pellets this weekend and it is throwing a lot more heat and no clinkers today with still about 4" of fire out of the pot. I know this does not pertain to the Englanders... it is just suprising how much difference a small change can make.

3 hrs. total time adjusting,and 3 cups of coffee.

Don't you guys have beer in Maine???
 
Why blower speed 9? Isn't that deafening?

Mine isn`t deafening on 9 . Sure, it`s louder than on lower speeds but show me a fan that isn`t.
If the stove is outputting good heat then why not set it on high and get that heat off the exchanger and circulate it faster.

I agree. AOT has nothing to do with it.
And yes! The PDVC is one slow stove to respond to setting changes. Always allow 20 minutes or more after a setting change for the stove to settle into a reasonably stable and smooth burn. I usually allow a half hour. I have even replaced the control board and it too responds to setting changes in the same way as the other one.
I`ve learned to accept and live with this stove for what it is and now that I understand it better it has become more predictable and enjoyable.
 
all together, the adjustments took 3 hrs. when i left and went home at 830 pm last nite, their house was a comfy 77 deg. i just got home from work and called them to ask how the stove was running, and she said it ran all nite and all day today,and stayed at 77 deg.

they are very happy right now, so even if i dont know for sure waht i did right...at least it was right.

I have had a few years w/ this stove, and mac hit the nail on the head. AOT = (air on temp) = room air blower temp on. Should always be at 1. LBA is Low burn Air, and is related to LFF, which is Low Fuel Feed. The last 2 are inter-related in that they change the LOW BURN charecteristics of the fire. I think they only affect the 2 lowest heat settings, but I really don't care about that- I only care about being able to have a usable, efficient fire that STAYS LIT at the lowest possible temp setting, 1. There are subtle differances in the mechanics of the stoves that require this. Then I adjust the LBA to make a pretty fire. That way, I can use my stove to take the chill off of my house during the shoulder seasons, without worrying about it. Running the room air blower at 9 all the time is just plain stupid. They would NOT have this adjustment, and it's associated costs of electronics, etc. if it was not for a reason. It is noisy when it does not have to be, wastes electricity ( I have a watt meter on my stove and watch EVERY little bit of electricity used), and is contrary to the operators manual. Not even a little bit logical. Actually, now that we have brought up the subject of the room air blower, if you move it up past where you can HEAR a differance in the SOUND, you are wasting electricity. Blowers like this have a maximum RPM under load, and that load does not change in this configuration, so in my case, it stops turning faster at 7, but when I turn it up to 8 or 9 the watts goes up but it does not move any more air. Costs you MORE MONEY FOR NOTHING!
Happy to hear everybody is happy, though!!
