Good evening

I have recently moved into a new home that has an quadrafire cb1200 FS stove. I've been battling with an lazy flame, after an very thorough clean of the entire exhaust path and replacing the door and combustion gaskets it has significantly improved. Though in my opinion it could be burning more efficiently.

I've spent hours looking through these forums of similar issues and everything I've come accross I have done - except change the firepot gasket. Which I will do if the following comes up short.

The main reason im posting this is in hopes someone can upload a picture of what their firebox looks like. (Below the burnpot). There are two "trap doors" essentially from the bottom of the pot to the ash tray. My trap door on pot is good and closes properly. But something doesn't look right on the bottom trap door that goes to the ash tray. It's an an angle from the hinge that connects the two trap doors and there is an 2 1/2 inch gap. I would assume, to have negative pressure this trap door would need to be flush with hole to so it's not drawing air from the ash tray which essentially is where the fire is located...

So if someone could kindly take a pic of what theirs looks like, that would be fantastic as I can't seem to find anything online to show me if it's right or wrong!!

Thanks!!

Yup I fixed it. It seems whomever took this apart in the past, had a memory of an gold fish and couldn't remember how they took stuff apart. They had essentially put the pin under the bottom trap door hinge causing it to be raised up on one side. And the nut/bolt that the bottom plate opens and leverages on was also incorrectly connected. Now it's burning like a champ

I too just bought a house with a CB1200 in it. My issue, besides pellet quality is a question about the flame. I get that it changes depending the feed rate, heat level, etc. But isn't there a way to adjust the air as well? I had a Heatilator PS50 at my last house and that had a spot under the ash drawer where you could adjust air inflow. Anything like that on the CB 1200?

Negative, there is no damper on this stove. It only has the feed rate control inside the hopper and obviously the L,M,H on the settings. You kinda have to find that sweet spot that works for your space. I run mine 24/7 so it's a bit of a balance as the temperature varies outside. But it seems to do an great job. It was -35c yesterday, and I was running the stove on high. Kept my downstairs 23c and upstairs 24.5c - almost too hot!!

If you have any questions or need any info on the cb1200 just reach out - I've practically ripped this stove apart several times now

Our new home has a 16yo CB1200 and after following the flow chart, replacing all the gaskets, replacing the TC, testing the snap disks, a thorough cleaning/sweeping, blaming the fuel, much cussing and swearing off pellet stoves in general, it was still running with a lazy flame.

Lo and behold, the ashpan trapdoor was not attached to the firepot trapdoor pin and was in the open position the entire time. I ignored this originally and assumed it was only a function of dumping ash.

Connected everything properly and now it’s a night and day difference!

Thanks, this post saved the day.

Cheers!
