Enviro Maxx 1 wild flame

[StrayFromThePath]

I’m having issues with my enviro maxx1, the flame is completely out of control to the point it’s burning up the burn pot.
I do clean it regularly, the feed rates on the lowest setting, the combustion blower is on the second setting. All of a sudden this started. Never had issues with it before and now the flame is up the glass and excessive. Tried changing combustion blower rate and also the air intake…. This affects the ash build up (more and blacker ash) but the fire still rages on. Really not sure what’s else to do and or try at this point.

Is this in manual mode, or are you using a thermostat? Do you have outside air installed? Need Johneh the Enviro guy to see this.

Welcome to the forum
Wild flame with black tips indicates a stove that is due
for a complete cleaning. From air intake to exhaust termination.
Not just a combustion chamber cleaning, but panel removal, all
exhaust passages vacuumed. The combustion blower removed and
cleaned, and the chimney cleaned
Does the stove have an outside air kit? If so, make sure it is also cleaned
nothing is plugging it. Ash, a pellet stove's greatest enemy

Outside air yes, thermostat. I had it running all last year and start of this year with no issues. I got no clue what to do anymore.

I’ll give it a through cleaning again but I don’t know if it the issue. I’ll get back to you after I do this.

Have you changed pellet brands? The vent on the left side should allow you to tone it down if need be.

I changed this year, but they are very similar and ran through ton and 1/4 or so before this issue began. I think it was the seal on the plug for the stove pipe clean out, as not much came out when I cleaned it. Now the heat output fan won’t kick up to speed. Stoves running and blowers running but for some reason if the heat output fan is on the highest or the lowest setting it’s running the same speed. It’s the speed it runs when it first turns on and before it gets fully running and kicks into gear, if that makes sense.

So I did and it’s flaming better now. I think the issue wasn’t cleaning but the gasket on the plug for the clean out of the stove pipe had rolled and wasn’t sealing properly.
Flame is much better now, BUT for some reason now the blower won’t kick up to speed. I can toggle the heat output setting and the fan doesn’t change speed if it’s at the high end or the low end. Not sure why it’s doing this now. I’ve never had this issue. Any advice?

On normal programming for the Maxx it will only run on high when the stove is set at 3 or more. I have mine on a snap disc that puts it on high when stove is on 1. What is the lt side damper set at?

Do you mean the heat output when you said “3 or more”? I have the heat output set on high, Slide damper is just a hair over half. Flame is about right now and the ash color is much better, lighter, just the blower won’t kick onto high.

Thank you for your responses I sincerely appreciate it.

Yes heat #3+

so I’ve cleaned the stove deep as possible, I’ve changed pellets, and I’m running the damper wide open. Flame is still way too big. I’ve determined there has to be a feed rate issue. I have it on the lowest setting and it’s still dumping pellets every 2-3 seconds. In the start up the burn pot is mounded, as it burns it gets down to a more manageable level.
To recap:
Feed rate is at 1
Combustion blower is at 2
Damper has been run from half to wide open and it doesn’t seem to make much of a difference either way.
Swept stove pipe, pulled everything out and cleaned the stove, including the exhaust system. Nothing clogged, air moving well.
I do have a professional coming next week but really hoping to figure this out and get the stove back up and running well as it’s been super cold here lately.
I appreciate you guys trying helping me out with this.

Thread 'Enviro Maxx problems'

Jan 19, 2016

Just had new stove installed by a Enviro dealer 3 days ago. No dealer adjustments or help after the install.
The burn pot overflows and unburned pellets fall in to the ash bin and catch fire. So far 3 ash bin fires in 3 days. Flame is bright and active. Heat output is good. Good quality pellets. Heat level on 4, feed rate on 1 (lowest),combustion level 3. I've read owners forums, watched youtube videos and read the owners manual 50 times. I'm really depressed I've spent $4,000.00 for a stove that does not work. Anyone been down this road and have any solutions?

Maybe the repairman can check the vacuum and perhaps re-program the feed?

 

[johneh]

Reset your feed rate to 4, which is the default setting
Set the gate at about 50% opon .
All the adjustments should be set with the stove warm
If you have no improvement, maybe the board is faulty.
loose connection on the wiring harness
Double check
NOTE: If the system light is flashing, the Control Board has complete control of the unit. When the unit's system light becomes solid, then control of the unit is given back to the operator.Check the position of the Thermostat slide switch on the Circuit Board

I’m scared to set the feed rate to four honestly, the flame is massive with it on 1. When you say set the gate you mean the damper, correct?

 

[johneh]

When you say set the gate you mean the damper, correct?

That is correct
The reason to reset the feed is as a test . If the fire remains high
I would suspect the control board has gone bad. Ssyko has a greater
knowledge of the board than I do . I can diagnose and test them when they
are in my hand, but without the hands on it is all speculation

 

[Ssyko]

If you have the board programmed (4lights flash in program mode only) then stove on run the heat setting is on 1/red led on first block, 12-18 min of running it will go to operator mode you now have control of the stove. How far open Is the damper/vent gate? About 25% -30% is a good start. If heat setting #1 is way to high after stove is in run/operator mode let us know and we can continue 😎

So I’m still fighting this stove, had a tech come out and check it out…. Didn’t really come up with much of anything. He did say it seemed to light slow and suggested a new igniter, even though it’s under two years old. So I did that and it still regularly missfires and is really slow to light. I’ve swept the pipe, cleaned the exhaust and stove regularly to just make sure that’s not the issue. Just can’t seem to get this thing running right. The flames more manageable most of the time, but still runs away in the beginning cause of the slow ignition but the ash is still coming up black more often than not. I’ve had to turn down the heat output to keep the flame manageable, but those two things shouldn’t be connected…. Right? My settings are currently… feed rate 1, comb blower 4, heat output 4. Damper is about 60% open. Any suggestions?

How tight is your Home?
Do you have an OAK (outside air kit) installed

The homes decently tight. I do have an oak that was installed when the stove was put in.

Have you opened the damper on the left side? Heat setting 4 is some big time heat have you tried 3, 2 or 1? The feed during start up is not adjustable. Stove turns control over after 15 min.

 

[stovelark]

The Maxx flame can be intimidating, it is a powerful stove too. On startup, if you have hot burning pellets, that are feeding a good load initially, the flame will be large. For slow startup, burnpot set in correct, air control set right? I find about 1.5 inches of silver between stove side and black knob handle is about where most Maxx's go. Does the control board seem like its working? Did this come about cause something changed? These guys here are good Enviro people, is the convection blower coming on and changing speeds with heat level changes of the control board? Good luck with her, the Maxx is an animal heater.

 

[stovelark]

R-read thread again. You're in t-stat mode, hi/lo? You say heat level 4? That will be huge flame. Suggest putting feed rate and comb fan rate back in factory settings. Having the damper fully open, it will have difficulty lighting. If your exhaust path is clean, what you are saying doesn't make a ton of sense, any error flashing lights on board? I'm wondering if your control board took a hit... one thing though, I'd suggest getting the stove to run normal in manual mode if possible, then go from there, to see if board is working normally.

I have the damper a bit over 50% open. I have it heating all three floors of the house so the high fan helps it circulate in the house better. Last season I had it at four and had no issues at all. The ash was perfect white, no misfires, no issues at all and this season for some reason nothing but problems.

I don’t know what happened honestly. It was running amazingly last year. Great white ash, flame under control, no misfires. No idea what’s different this year but the stove just seems all over the place. I tried changing pellets to see if that was the issue. I moisture tested them, They are stored inside where I buy them, and at my house before use. I sweep the stove and the pipe regularly. Just can’t figure out where the problem lies. I’ve tried all the adjustments between damper, feed rates, comb blower, and heat output. Things have gotten a bit better but still struggling with misfires and huge flame from time to time. I’ll try changing the damper to the 1.5” you are suggesting and see if it helps me get back to the ash burning completely again. Thanks for your post, thoughts, and time.
