So I got my dads older (2011) G200 installed this fall and got it fired in November and it had been working great. At first I think he was overloading it a little and he was getting some creosote dripping out of the main door and some moisture at the lower ash clean out door. But now it seems to have a hard time gasifying. It will be loaded up and burning well with the main door open but when I close it and open the ash door its not gasifying or it is but just a little bit. I know the seals are probably bad and I can see a little smoke coming out of the main door in two spots but is that enough to keep it from gasifying? The chimney is clear as are the exchanger tubes, and I have tried clearing the nozzles on the refractory brick to make sure they are open. Also the solenoid is working correctly and the flap is opening. I tried to remove the air box on the back to see if it was clogged but could not get it off. It looks like it only has two bolts holding it but I can not get it off. Any ideas?

Hi maveric.
When I open the bottom door on mine it also goes to a very small flame. When the door is open it is not hot enough to keep to keep the correct balance of gas+oxygen+heat. Did you make sure the side holes in the nozzle are clean. Other than that it should b gassing in there. When you see just heat waves out the stack. Sometimes mine will bridge creating blue smoke. I just rake the wood around some, Then It goes right back to clean burning. Where are you located? If you can please add it to your profile. Thanks.

It still has the draft inducing style fan correct, it pulls the smoke and gas through the boiler? If so you will not get any gassing once you open the lower door because it has no way to pull the gas through the nozzle after you open the ash door.

Like the others said, once you open the lower door the stove looses negative pressure and can’t pull any more air thru it, unlike a forced draft stove like a P&M Optimizer.
I made a view window for mine so I could see the secondary burn, it’s nice at times but still requires regular cleaning about once a week as the glass will smoke up when it idles.
My prototype design allowed a lot more air in for an air wash to keep the glass clean and clean it kept it, but it also allowed enough air in when idling to cause a little more creosote when it was warmer.

I think you have a first gen G200 with horizontal tubes which has a pusher fan.It's a different animal. I know of someone that has one and loves it, with no problems. Dry wood is key.I am told you can get creosote in the air induction tube and it makes it hard to remove it. There is not good access to the air system and you may have to call Heatmaster to get advice for for removal. There was not a lot of those units made and the advise from current G200 owners may not be accurate. Pusher fan will let it gasify somewhat with the bottom door open but top will have to be closed.

Thanks for the advice, after reading these and looking more at the stove it must be gasifying pretty good based on the wood being burned up and the ashes it leaves. It seems to burn everything up really well, when I clean the ash area it is a real fine powder. I guess I am used to my Empyre Pro 200, I can open the lower door on it and see it gasifying away in there and just figured his would be the same way. Other than a couple drips out of the doors I know it needs new gaskets, my dads stove is doing very well. I guess I will have to call Heatmaster to see how to remove the airbox to clean it, like I said I had all the bolts loose but nothing would budge.
