Pelpro 130 pellet stove won't stay lit

Maybe too much draft? I would put all the trim screws in the middle of their adjustments to start....then adjust the draft stick

My PelPro isn't the same model... It has 3 trims I can adjust and a draft stick that I can pull or push to adjust the flame.

I run the fan trim at about 1/3 it's full speed

That would be my guess too Tami and I would say if your fire is going out leaving unburned pellets then you need more air not less or less fuel not more.. Assuming that trim control on your stove runs the exhaust fan then turn it up, that will increase air supply to some degree.. The trim on the Harman stoves doesn't have huge effect but adjusts for a slight variation in house voltage from normal. Not sure on your Pelpro. You would have to experiment I guess, but at least you know you started out from 0 ! You can always get back there. I'm not finding anything online about that trim setting either. By some odd chance it may run your pellet feed auger, then turn it down if you have unburned fuel in the pot when the stove croaks out, delivering less fuel..

I did find a video explaining about the blinking light for errors on stove shut down faults.. I think in your case I'd start out running in the Auto mode set someplace near mid way and adjust from there.

Now now...patients. You will getting working. Most of these stoves are a process of elimination to figure out what is wrong. Unfortunately, it is usual something simple and obvious which is overlooked. Hang in there.

Just a thought, check and make sure the exhaust probe and ambient temp probes are seated correctly and did not get knocked loose somehow. Where it starts and then goes out makes me wonder if one of them is boarder line loose. From the diagram they both look like they have the potential to work their way loose.

That there I just checked exhaust probe is still in its brackets screwed firmly on and have followed the wire down to where it plugs in and have checked all connections the ambient probe is in place and plugged in. I do appreciate everyone's help thank you

Are you saying that you started with the trim setting at 0 then experimented and now you are back to 0 again, and it ran well for 12 hours ?

With my Harman at about 12 hours is when I would scrape the pot which on the Harman pot this can be done with the stove running and is suggested to be done with the stove running,it takes less than 1 minute to do.. You just take the tool and scrape under the burning coals of pellets and scrape off excess ash. With ashy pellets this will affect the flame path if left alone. I could see with a different pot design how that could woof the fire out. IE, I wonder if in 12 hours you need to scrape the pot.

There was a guy here last year with a similar problem in a different brand stove, there might have been the difference that he was getting an ash bound fire pot within hours of start up then the stove went out.. We suggested trying some super low ash soft wood pellets and see what happened. He was able to round some up somewhere and the problem went away.

I Get It ! Frustrated.

On a recap: The manual says max horizontal venting is 4ft, including counting for elbows. And a 60" vertical rise is actually recommended. It also states not to run it in a negative pressure situation. Negative pressure meaning house internal air. Some really tight houses go into negative pressure effect with things like pellet stoves and cloths dryers running at the same time. I don't recall if your stove was set up with outside air or if was drawing from house air. I'm just fishing for something generic here !
