Just installed a new cab50 cleaned the pot and chunks of pellets dropped into the ash pan. I am new to pellet stoves and was wondering if this is normal. The chunks were about 3 inches long and 2 inches wide. They had holes through them. Any advice or comments would be appreciated.
 
I saw your other post about this. Please post pics of the "pellets".
 
I know what you are talking about. It's like black clumps of ash. If you put a little bit of pressure on it will fall apart. I'll try to post a pic once I clean out the burnpot.
 
Sounds like the start of a clinker.....

That's why that clean out rod is there. Pull when necessary.

Is this normal or is this something I should be worried about?
 
What pellets are you burning?

Is your damper inside the ash drawer Wide Open? (Under the ash pan)?

I don't see anything out of the ordinary here, maybe a little more firepot crust in the ash pan than usual. Is this one days pull? If your not getting misfires and have a good flame I would say everything is fine.
 
Here's my burnpot after 1 night.

That's a lot of pellets in the ash pan. Did they fall out of the shoot when you were pulling the cleaning rod. Other than that looks fine to me.

They fell out when cleaning the burnpot. The stove was off since the ash covered the burnpot.
 
I get those after burning hard for a day or two in my CAB 50 and not cleaning out the burn pot. The manual says to pull the burn pot scraper every day and then use the tool that was provided to clean the edges and holes with it open to drop the ash into the pan. Like what was said before, the pellets that were at the top of the chute will fall sometimes. No biggie there. Out of curiosity, have you (or anyone else) ever adjusted the damper below the ash pan on the CAB 50? I can't even get it to unscrew, let alone twist!

I'm too scared to adjust the damper. To be honest, I didn't even know those could be adjusted.
 
ash looks good. The clinkers are from to much silica in the pellets.

Stove is making some weird sounds when it first starts up. Sounds like a freight train is coming g through the house. Goes away y once the blower kicks in. Is this Norma or something I should be worried about.
 
I saw someone above ask about what brand of pellets you're burning, but you never answered.

Its somewhat normal. But is normally caused by to much fuel at start up.

Is your flame height set according to the manual? If so, then is the stove shutting off for a decent amount of time? If the stove is short cycling (starting up and shutting down all the time) then the T/C may not be getting below 200° inside the firebox.

Remember, the pot is cast iron and the T/C is inside a ceramic cover. Both of which retain a good amount of heat. Eo even though both blowers are shutting down, if the stove doesn't stay off long enough, the residual heat inside the stove will make the T/C still think it should feed pellets.

Normal start up with cold T/C is, Stove feeds pellets for 60-90 sec (depending on model) then stops feeding, ignitor lights pellets, flame gets T/C to 200° and tells auger that stove is lit and to start feeding pellets again.

A start up with Hot T/C is stove feeds for 60-90 sec then still continues to feed pellets at set heat rate, because it thinks its lit. So the amount of fuel will almost double by the time the stove lights. Add into the equation a feed gate that is open more than it should be and your in for some rumbling!!!

What type of swing or span do you have on your stat? A 3°-4° ((total) is pretty good, depending on stat location.

So if your stove is starting up less than 30 minutes after it shut down, its likely to hot still. I would either lower the feed gate some or lower the heat setting to get the stove to run lower and slower. A stove set to High, will quickly heat the air in the room and satisfy the stat, but will still feel cooler than running on Med (or even Low) and heating slower, but heating the entire contents of the room. Which in turn makes it more comfortable and keeps the stove off longer because the room has soaked in the heat.

My 2 pennies.

Mine does the same as well. I noticed that it only happens when the stove is cold and just starting up.

Close the damper in the hopper by 1/4" until it goes away. Allow time for it to adjust to the new setting.

My cab does this on cold start only also. I was told it's because of the heavy cold air in the flue or pipe. The warm exhaust has to overcome this. Until it's hot enough to do so you will have back pressure on the exhaust blower which causes some vibrating.

Eric, what's your take on this? Makes sense to me.

On the combustion blower there is a plastic countbalance/cooling hickamadoodle. On the initial feed is causes that to spin a little faster than normal and the noise starts. This is my take on it and some of you astrophysics might need to inform me of something else.

Damn, those hickamadoodles!
