HI, first I'd like to say great forum and I'm glad I found it.. I just made the switch form wood to pellets and with the great info here I decided on the 52i insert for the living room and a p68 in the basement. with all I've read and heard I should try to maintain about an inch or so ash lip, but even with the feed rate cranked up to 6 I still cant get the ash or pellets more than an inch or so out of the burn pot. With the stove in idle most of the fire is at the auger and burning the pellets up to the second screw in the auger. I'm burning new England premium pellets and running both stoves in room temp/manual. Is this a normal was these burn or is it the low ash count in the pellets , or maybe the warm temps now aren't putting the load on the run times keeping the fire low in the burn pot,,??,, Thanks for any input and such a great site

The feed rate setting only effects the maximum feed rate. To set it using your current mode of operation first set the temp. to the highest setting so that it is calling for more heat and let it run for a minute. Somewhere between 3 and 4 usually works well.
 
I started out with the recommended 4 setting but it seemed the amount of pellets wasn't enough to get the ash to the recommended 1" from the lip, mostly the fire is right at the auger output. I guess I am thinking having the burn right at the auger could creep up in to the hopper ??
 
The most probable reason for such a low flame is because you have already met the room temp, so it is going into idle mode (since it is in manual). It will just keep enough to keep a flame alive. Turn the temp dial up to 80, and watch that sucker come alive :). This time of year it is easier and IMHO more economical to run it in room temp/auto. Then you will have a nice flame and it will shut off after room temp has been achieved (it will idle for a short time, then shut off if no call for heat). I don't use manual until much later in the season.

You shouldn't have to worry about it burning into the hopper - I believe it is a double auger system.
 
Your fire looks good. You will not always have pellets out to one inch from the end of the pot and only an inch of ash. The best thing to do is just set the feed rate at 4 and let it go. Are you using room temp or constant temp setting?
 
I have a 10 month old Harman p43 and I have never got to 1 inch from the lip of the pot. My house gets warm and I figure I'm saving pellets. I imagine different pellets produce different amount of ash also and that would affect it also. I wouldn't worry about it and just adjust to the amount of heat you want but don't get less than the 1 inch rule. Just my opinion.
 
Don't worry about the ash distance.... As long as the fuel is burning hot, you don't need the ashes to be close to the edge. The only way ash gets closer to the edge, I'd if you are demanding a lot of BTU's from the appliance, so it feeds a large amount over time.... Hotter pellets will satisfy the ESP easily, so there's no need to fill up the burn pot so much.

RELAX..
Your flame is fine..
burning with a Harman also and I really don't pay too much attention to where the ash line is especially if I am burning super low ash softwoods.
so light that at times no Ash line showing..
you can tell when your stove is burning correctly just by the good strong white/yellow flame.
Keep the feed rate 3 or 4 and let the Harman do the rest..
 
The one inch of ash from the edge is when your stove is heating at its max out put. You would set your feed rate at that time so it isn't dropping un burnt pellets into the ash pan. If you see Un burnt pellets dropping into the ash pan under a heavy load just turn your feed rate back a little at a time until you get your one inch of ash as recommended. I have noticed a feed rate of 3 allows the stove to light faster as there is less pellets in the burn pot on start up making it easier to light the pellets rather than a feed rate of 4. Happy tinkering once you get it all dialed in you'll only have to put pellets in and walk away.

yepper..
do the same.
feed rate 3 for same reason you posted..
 
<------ works nights...
 
Thanks for all the input, like a said great site and good people here !,, set it at a 4 feed rate and room temp/man . Stove runs great, now I understand how its running and can stop worrying where the ash line is.. Now I need to do a batt back up, hoping to do both stoves with one inverter and a couple big battery's,, thanks again for all the great info,,,.

Think twice about a battery back up. A small sine wave generator will be a much better investment. The Honda Eu1000 and Eu2000 are great little efficient units.

yea I agree with the gen, just looking more for an option to keep the stoves going for a couple of hours, I've been lucky ( knock on wood. Lol.) where I live I'm close to the main line and rarely loose it for more than a couple of hours, but having my elderly mother living with me now has me looking for a gen also, the battery inverter combo would work for the small interruption's and brown outs at least by time if I wasn't home and time to drag out the gen..big decision is buy both set ups or bite the bullet and go with a whole house gen set, either way MORE MONEY !! ,,

We bought a Generac 7500 Watt Generator and a transfer switch which can run 10 different circuits from our main panel..
900.00 for the Gen/300.00 for the transfer switch box..
that said, during a power outtage, I run my Oil furnace instead.. that way we Don't have to worry about dirty or un-even power affecting our Harman circuitry.

Buy the smallest generator you think you can get by with. Not the biggest. They burn a lot of pellets per hr.

Great Tip...
next winter power outtage when pretty much our whole house is energized and heated I'll probably ask my self why I didn't get the smallest one and limit ourselves to maybe a lamp and a refridgerator and not much else...:rolleyes:

I have a whole house generator to get me through what caused the lights to go out. Once the storm passes, the Honda I2000 ( sips fuel ) comes out and gets it done until the power comes back on. Extended periods without power can be costly. Saves me a lot of pellets.

fully aware of the gasoline used to run maybe 12 hrs a day[shut off at night to not annoy neighbors.] around 5 gallons per 11-12 hrs. can't run a genny on water or air...
but, so nice to have the house powered up when all around us are without power
no one is concerned or counting gas cost during an outtage. happy to have the fuel.& Electric..>>
