there are alot of posts here on it.. you need a manometer.. they can be had for $25. we install them permanently. Draft can be measured when the stove is running strong and cold outside. Super Mag specs are in the manual.. I believe it's .04 to .06 ..
Controlled with a barometer of quality and the flap on the combustion motor. Others will link to pic's of manometer installs.. I ran 1/4 in copper tube in a compression fitting mounted in the flue pipe to near the manometer on the wall. The last few feet was the rubber tubing supplied in the kit. Rubber near a flue pipe or hot stove isn't good. Thus the Copper tube from the stove.
Also the rubber tube is installed in the opposite port on the manometer that the instructions tell you to do because the neg readings don't go that low.. so it is the same spec's just read on the opposite side of the scale.

The manometer is supposed to be hooked up to the front of the stove as well and read .. I didn't do it as I had trouble getting a fitting to do it with so I focused on the flue pipe reading.. I would think your pellet stove was supposed to be done the same. Being a forced combustion flow as well.

On a side note I have my feed rate set for 2 1/2 and fan speed about 1/3 ... the stove will over ride this all when demand great. Be sure to lube the 3 oil ports on the shafts in the rear with light oil. The filter you must know about that's in the bottom tray.. 16x16 has to be kept clear.

One thing with Rice you may get a large piece that will get by you and plug the feed entry in the bottom of the hopper thus giving a low flame due to lack of coal being fed... any issue check that first.. I use the room temp probe that lead up stairs with a added length of 15 ft to reach my area.. You can add more wire to it and it won't change the temp at all.. the dial might lay on 70 on the stove and the living room might be 68... no big deal.. just adjust the dial to your desired room temp.

Again your pellet stove must be similar in operation... I found the Mag to take time to settle in and adjust to all given factors.. but once it does it will keep the area with in a degree ...we start ours Oct 1st every year and shut it off in April sometime.. same temp setting 24/7.. don't turn it down or up.. it will idle down so nice in warm weather then warm right up with a drop in temps...

Mackman,
There are a lot of discussions on different threads in the forum about using barometric dampers (baro dampers) and the manometers used to adjust the draft to the stoves specs. Just use the search function in the upper right corner of the page to type in the keywords. You should get a lot of your answers that way. I use a baro damper on my Harman Mark II and it greatly increases it's efficiency. Welcome to the forum, its been a great place for me to learn a lot from the many knowledgeable people on here.

Rookie mistake. I forgot to empty ash pan. After 48hrs. Its was filled up. Like to the point of when I opened up the ash door it all came out on the floor. So. I shut the stove down. Waited a few hours and cleaned everything up. Definitely gotta stay up on ash. Guess my bobo pellet stove habits got the best of me. ;)

Not that I can recommend this but I vacuum my Keystoker with a hot fire in it and turned off. The shop vac is out side and a long hose to the stove does the trick. When done turn stove back on, rinse the hose out, and leave the vac in the yard for a day or 2 before returning it to the outdoor shed. If the vac busts into flames it is only a $60.00 black friday HomeDepot special anyway.

When I first got my Keystoker the family said I have a new GF :oops: I even named it Nicoal :!: Wife could of cared less, she was harmless :oops:

Been there done that.... I do like 2001sierra does... shut the stove off... for just a little while to keep the fumes from coming into the basement were the stove is and setting off my alarms... then move fast.. get the ash out and cleaned then turn the stove on before it goes out.. I have a small hoe I made to scrape out most spilling and then use the old shop vac with dust bag I have.. I use it to clean up all the small pieces of Rice that drops around while tending ...filling my tote near the stove to dry out the coal some before use..

I went thru grates finally with my Super Mag... If you have an extra $70 buy spare grates.. you may need them someday and no one stocks them..they are ordered.... I probably burnt them up over the 4 yrs.. it gets 30 to 40 below here alot and this home is big..stove runs full bore alot.. they had a hole burnt right thru the middle.. of the two..something went odd. I checked ..cleaned and installed new ones and it has been fine for a few weeks. ..so go figure..

Mackman how did you make out this season? I'll be running mine until April or so being the way it is here in Northern NH. I had to break it down and do a complete cleaning because it wasn't getting to the temp we needed... Seem's every once in a while I have to do that.. Clean the flue pipe because the draft get's lower... clean the feed path from the feed pusher to grates..vacuum it out totally..
This process for me always fixes it... wet coal ..old partially burnt coal..ash build up ...will take it's toll. The manometer shows draft is getting lower due to ash build up in the horizontal pipe going thru the outside wall to the outside chimney.. when cleaning I can see some solid build up of coal pieces chunking up in the sides of the feed path.. Grate holes start to clogg from minerals etc.

I will say after 4 seasons o Northern NH temps down to 40 below zero and often temps of 0 or below the stove has been fine..no parts broke except for my grates... don't know what happened there for sure but new ones are cheap $70 and install in a few minutes... it has been fine sine I did that.... the stove works very hard 24/7 as my house is very large...and the wife likes it 72 deg f 24/7.... In a way I wish I bought the LL dual burner stove back when... as long as I could of blocked the forced hot air from entering the stove room and pumped it up stairs like this Super Mag does for me..
