I hope you forgive me for typing this post with dirty hands. I just got finished cleaning out the St. Croix Prescott EXL pellet stove.
Actually, I gave it more than a regular cleaning, I gave it more like one of those seasonal cleanings that everyone says you should do, but no one does. I even took some pictures.
The reason for this post is really to follow up from a comment left by “Linda” over at my original pellet stove post.
Apparently, many fine pellet stove owners out there are having issues with their #2 light blinking. I received tons of great comments on my other post regarding this. We have all been looking for the answer. Linda offered a lot of insight, so I decided to give her ideas a try. I think the main point of her comment was to say that cleaning out behind the “ash clean out covers” is very important. I thought I had been doing that, but she mentioned that what I was doing, wasn’t enough.
Okay, so let’s get going. I am going to show you some pretty interesting photos in this post…photos that are hard to find. Sure, there are tons of good pellet stove shots out there, but usually when people start cleaning out their stoves, they forget all about the camera. Not me, my friends. Not me.
I first went downstairs and shut the stove down. When it cooled itself and shut all the way down, I unplugged it. That’s very important, so make sure you do it. After that, I gave it a quick once over to make sure there were no large piles of ash anywhere. I didn’t give it a good cleaning, because I just did that yesterday. It didn’t need to be done again. I did push some ash into the ash pan and empty it though.
What I want to show you here are those ash clean outs that the owner’s manual talks about so much. I just realized this morning that there are about 4 warnings to keep these things clean. I guess it’s pretty critical. I have been doing this every time I clean the stove, so I really didn’t think I needed to do it again. Linda mentioned that we should be cleaning these out with a bottle brush or something like that to really clean them well. Good thing I had bought one of the bottle brushes from Lowe’s a while back. It’s really made for a fireplace or stove, but I was using it to clean bottles for my home brew.

Notice how there really isn’t too much ash in there? I’m talking about inside the hole. I just vacuumed this out yesterday, but I can imagine what it would look like if someone never cleaned these out. Probably like a packed wall of ash.
I didn’t take pictures of the right side, because it is identical to the left side.
By pushing the brush straight up, I didn’t get all that much ash to come out. There really wasn’t all that much up there. By pushing it sideways, I got a little bit more. I’ll show you in the next photo.
To get the pile of ash in the photo above, I basically pushed the bottle brush straight through, from the left side to the right side. I actually saw the brush coming through the right side.
I figured that was done, since I saw all that ash coming out. I decided to move on to clean out the exhaust fan. This is one of those things the book tells you to call the dealer for. It took me about 15 minutes to do the whole job, so it’s up to you.
To remove the fan, I took off the 6 nuts that surround the motor. I believe I used a 9mm 6-point tall socket. I also removed the vacuum hose and took off the vacuum switch wires as well as the fan wires. After everything was removed, the motor and fan popped right out.
With the fan in hand, it was easy to clean the blades (if you call them that). You can use an old paint brush or a rag or something like that. Just get the ash off the blades. The owner’s manual says this fan does not require oiling.
I also decided to take a photo of the rear part of the exhaust vent. This is one of those things we always wonder about, but unless you have taken a pellet stove apart, you will most likely will never see.
As you can see, there wasn’t really too much ash buildup on either the fan or the exhaust vent. I brushed them off and put everything back together. I lit the stove up and watched it burn for a while. I haven’t yet put the wires back on the vacuum switch. I still have them jumped. I’m not sure I have the heart to go through that again, since the stove has been running so wonderfully the way I have it now.

As I mentioned earlier in the season, we had a St. Croix Prescott EXL pellet stove installed in the basement.
Before the Winter season really began, I had my doubts on whether or not the pellet stove would heat the entire house. I was worried that it’s location would hinder the airflow to all the rooms upstairs. Well, I am happy to inform you that the stove does heat the entire house. I mean, if we keep the master bedroom door shut, it does. The master bedroom is over the garage and the furthest room from the stove. It’s also the coldest room, which is why we keep the door shut. When the time hits 10:30PM, the new digital thermostat cranks the heat in that room up to 65 degrees. That’s good enough for me.
We have had some nights already where the temperature has been in the 20s. I think that’s Winter and enough to tell me that the heating situation is going to be okay. I did try burning a fire in the regular fireplace a few times while running the pellet stove. The fireplace actually made things worse. It sucked so much air out of the house, all the rooms dropped a few degrees. Fireplaces are remarkably inefficient and really shouldn’t be used, in my humble opinion. If you want to run something in your fireplace, run a free standing wood stove or a wood stove insert. Even burning a fireplace for aesthetics on a cold day will freeze out the rest of your house. Nuff said.
Okay, we are having a little issue with the pellet stove.
A few nights ago, I tried to start it up. The start up procedure really isn’t very difficult on the Prescott. It basically consists of pushing the “on” button. Once the “on” button is pushed, the room blower turns on for about 10 seconds and the auger turns until the burn pot is approximately half way full of pellets. As the auger is turning, the ignitor kicks on and the pellets light up. It’s fun to watch and I sit there almost every time I light the stove doing just that. I smile when I see that flame dancing around inside that pellet stove.
Back to a few nights ago…when I tried to light the stove this particular time, I pushed the button. The fan turned on for about 10 seconds and then the stove just shut off. I am not sure if the auger ever turned to drop pellets into the burn pot.
I tried to light the stove a few more times when I noticed the #2 light blinking on the control board. I thought this was a little strange, since I had never seen that light blink before. I pulled out the owner’s manual and looked up that error code. Apparently, a lack of negative pressure causes the stove not to light and the #2 light to blink.
What can cause a lack of negative pressure? Well, a really windy day can do it, an open pellet stove door, a fireplace burning upstairs perhaps, a clogged air feed pipe or a clogged exhaust vent pipe. I am sure there are others, but these are the ones I remember.
Since I had a fire already going upstairs in the fireplace, I chalked the whole thing up to that. I got the pellet stove going in this instance by pulling the rubber tube off the vacuum switch and lightly sucking on it. When I heard a little “click,” I pushed the on button again. From here, things were fine. I held the crimped hose for a few minutes and then I hooked it back up the proper way.
Well, I tried to light the stove again the next night. The same thing happened. Since we had no fire going in the fireplace, I thought perhaps there was a clogged area in the stove somewhere that is causing the lack of vacuum, or negative pressure.
Let’s make a really long and boring story a bit shorter and to the point.
I cleaned out the entire stove about 10 times and nothing has changed. Every night, I suck on that hose to get the stove up and running. I have been reading the owner’s manual as well as some websites that deal with this kind of situation, but nothing has helped. One website said that a clogged exhaust vent is the sure-fire problem. I got excited and took off the clean-out cap. A little pile of ashed dropped out, but nothing changed.
This afternoon, I called the pellet stove dealer. I told them that I had pretty much narrowed the problem down to a faulty pellet stove vacuum switch and that I would need the tech to come out and take a look. Before we swap out the switch, I want him to hook up a vacuum gauge to see if there is proper negative pressure. If there is, we can replace the switch…if not, we have to do a bit more digging.
I keep going downstairs to investigate this issue. It is in my blood that I try to diagnose this problem myself. The only things I don’t have are a vacuum gauge or a new vacuum switch. I guess I need those things to solve the problem.
If you have ever experienced something like this with your pellet stove, please let me know. I am racing against time here. I want to beat the repair guy and figure this out myself.

Well, the guys came over yesterday to install the new St. Croix Prescott EXL pellet stove. As you might recall, our previous pellet stove was a Harman P38. I was a little nervous about switching brands because I had gotten used to Harman. Also, Harman has very good reviews. The reason I couldn’t get a Harman this time is because they are all backed up and we may not have even gotten one this season.
It took the installers about 3 hours to finish the installation. When everything was in, they fired it up to make sure everything was working properly. One of the installers noticed one issue…the auger wasn’t turning, so no pellets were falling into the burn pot. the auger motor was working fine, just not the auger itself. We made an appointment for the service guy to come out today. By the way, I could have fixed this. It was easy. I actually was almost done fixing it when the doorbell rang. That’s me beating my chest.
Today, the repair guy came out and fixed the auger issue. The small set screw on the auger shaft wasn’t tightened properly, so it wasn’t catching on the auger motor.
I must say, this unit is very nice. It has auto-light, which was very important. I am going to hook up a thermostat, so the pellet stove can shut down and start up on its own. Also, the auger and fan is much quieter than the Harman. The whole system just seems to be more elegant. For a few hundred bucks more, I am happy that I went with this model.
Here are some photos…
What’s nice is that the outside venting is under the porch. The necessary clearances are 24″ away from the porch and 12″ off the ground. Also, since we used the fresh air kit, the clearances from windows and doors is only 9″. I would say that’s one of the huge benefits of pellet stoves.

I know it’s only July, but believe it or not, that’s about two months too late when someone is trying to get a pellet stove installed.
I stopped by the local pellet stove store the other day to pick out my new Harman P68 Pellet Stove. This is top of the line and has everything I want in a stove. There is a thermostat and auto light and everything else I can think of. You can understand my excitement about this after I received a “price lock-in” at $4.85 a gallon from our heating oil company. As it turns out, a lot of other people are excited about Harman stoves as well.
I walked into the store and told the sales guy that I wanted a…He said, “If you are going to say Harman, you aren’t going to see it for a while.” He explained that all the Harman stove models are way back ordered and I wouldn’t see it until way into the season. While this annoyed me, it also gave me a chance to look at some other stoves.
I looked around and picked out a St. Croix Prescott EXL. This has the thermostat option as well as auto-light. When it gets too hot, the fire goes out. When it gets too cold, the stove automatically fires up again and cooks until the whole thing happens again. I am telling you, these things have come a long way.
I put a deposit down on that stove and they are going to come do a site visit, just to make sure the whole thing is going to work out, permit-wise. I think it will.
I also looked at some wood stove inserts for the fireplace upstairs. They look really good. I told the guy that I really wasn’t all too attracted to bringing wood inside again, since my childhood was filled with that. Then, he showed me the bio-brick. A bio-brick is a two pound brick made out of compressed saw dust. Basically, it is a big wood pellet. You can order them by the ton, just like pellets. I though this was wicked cool and now plan on getting a regular wood stove insert for the fireplace next season.
I will let you know what happens with the site visit.
