help with a new envio m55 cast iron

[ic1334]

I just installed a new castiron m55 with a oak. my question of problem is on high i get lots of heat but when i turn it down to 3 or below it loses alot of heat, on 2 it is very look warm and on one there basically no heat at all.
im trying to heat a space of around 900 sq ft . that is a stone ranch house with new windows and doors, i have read on here where other have no problems heating a space much bigger than mine on the lower seating. i am currently using lignetics premium quality pellets from last year that have been stored in my house.Is there a something i missed during set up or is there something else i need to do?
Thanks

Hey ic1334. If you can, let's start with some pictures of your install. Is this a free standing stove or insert? Something's amiss as the M55 on its lowest heat setting will keep 900 square feet very warm. Folks are going to want to know how your exhaust is vented out. We need more install info. Some folks are going to ask if you used a magnahelic gauge to set up the air....or by how the flame looks. I am no expert but I am guessing the stove is performing poorly for lack of air.

 

[ic1334]

its free standing, pretty straight install. 4 inch pipe straight out the wall with an outside air kit on it. piece is no longer than 2 feet long total. i dont know what this is magnahelic gauge. as for the flame on low you can barely see it in the burn pot on high its a pretty big flame
thanks

4 inch pipe straight out the wall with an outside air kit on it.??????
Are you saying you have just one pipe out the wall? With an outside air kit "on it"?
If you have an OAK, then you would have two pipes through the wall....( in most cases ) It sounds like you have just one pipe going through the wall....if so that is half your problem. Can you describe the OAK kit that you put on the end of this pipe.....? Your exhaust port and fresh air intake are two different ports....
You should have a very decent flame even on heat 1...
Still think your not getting enough air.

The oak goes into the same pipe as the exhaust. the pipe has a 4" center pipe with a gap around it that makes the pipe a total of 6.5" the exhaust runs through the center pipe and the fresh air comes in through the gap around it. there sealed from one another.

Okay, that will work! Assuming that this new stove is in perfect running condition then all I can com up with is that your not getting enough air for proper combustion. On the M55 during the initial start-up, you should have a very large, w i d e flame one that reaches the baffle tubes...even in feed 1, heat 1 and air 1. After the initial start-up then the flame will die down according to you settings. I am curious as to how much you have opened up you air baffle? The only other thought is the inside room temp and if you are running in Auto or Manual and hooked to a T-stat. In any event, if you run the stove in Manual with heat level 1, feed 1 and air 1, that stove should produce a decent flame and bake you and you 900 sq. feet with no problem. Hopefully another M55 owner will help you out...Good luck for now, Bill

Im running it on manual and i haven't made any adjustment to the factory setting. also after watching some of the you tube videos, i can see that my flame isn't as big as they are showing.it is still using about 2 bags a day,it just doesnt seem right. last night i had the temp up to 73 in the house. I turned the stove down to setting 2 and when i woke up the temp was down to 66.
Bill thanks for the help

does anybody know the typical setting they use for com and feed rate? also is there another way to set the stove without using a magnahelic gauge

Hi IC- the M55 fs isn't as easy to adjust as most enviros, but with the side panel off, unloosen the lock down screw and the slider probably should be nearly closed as you have a short run there. A magnehelic might be necessary to dial it in correctly, but would think it will not be open much. I would suggest a magnehelic in your case and it can make a big difference in heat output. About .20 in/WC on heat setting 5 should be ideal. Hang in there, you got a great heater, it just needs adjusting.

While it could be something completely different, your symptoms sound similar to something I had. We bought our pellet stove when we had renters in the house. When we first moved back into our house a few months ago I noticed that our flame on heat level 1 or 2 was very low. I found a youtube video showing flame patterns for the M55. It sounds like you may have found the same video.

Anyway, after investigating for a bit, I found that the auger feed motor was a 1 RPM motor when it should have been a 2 RPM motor. I'm really not sure if the stove was shipped like this or our renters replaced the motor for some reason.

The confusing thing is that the manual calls out part number 21 as "Auger Motor 2 RPM". But it calls out part number 53 as "Auger Motor 1 RPM". But part number 53 is actually the agitator motor. So a guy could get confused if he wasn't reading the parts diagram real well.

So I bought a new 2 RPM motor for the auger (Enviro part 50-2054) and now my flame looks like the video.

Sounds like you need to set the auger feed cover as well. I have found in certain places the cover needs to be opened up 1 hole or more. Than i adjust the airflow with a magnehelic gauge. Sometimes when new those m55's end up with the air slider almost closed to get the factory readings. I usally start with the slider at 1/2 inch from the bottom than run on high for 1/2 hour, at that point i set the stove at .20.

Or you have a pile of dust in the hopper

Did my first cleaning yesterday, only owned it a week. and noticed the air slider/ damper on the back of the stove was all the way open and the set screw was never tightened. So after getting a few tips on here i closed it quite a bit , left it about 3/8 opened. that helped alot. the heat got better but on setting 1 you cant even see a flame but the air is warmer than before.2 is barely out of the pot. feed rate and combustion rate are both set at 3. should they be even or should one be more than the other? does raising the feed rate do the same as raising auger feed cover?

 

[skinanbones]

The feed rate and combustion trims on the circut board are for fine tuning. I don't adjust them until i've exhausted myself adjusting the auger feed cover and the air slider. The circut board trims are just adjusting the voltage by .5 volt + or - and they don't have that big of effect.

after reading your post i took your advice and raised the cover one hole. it has 5 total holes, when i started you could see through 3 of them, now you can see through 2 of them. does this sound right? i just started it up about 10 min ago, waiting to see how it works. it just seems that there arent many pellets in the pot a one time.

 

[skinanbones]

yup that's way to go, it will take a bit to settle in and starting running right
