Over the past week, I've got this dead spot on the right side of my Mk II. It's the whole depth of the firebox, front to back for about 4" from the side.

I let things burn down and shoveled out any ash in that area, got it going again and it came right back.

The fire went out so I started right from scratch and this morning, I have the same dead spot even though I've got a rip roaring fire in the rest of the stove.

For the warmer weather, I switched over to pea but it was burning fine up until this week.

I found on my mark 3 is I don't poke it every so often(burning pea especially) I get dead spots. My guess with the pea is possibly plugs the grates up just enough to limit enough air for burn? A good poke usually helps.

If the air is uniform so will the fire be. Maybe a less deep bed with pea.

Or it could be the work of Samhill who wants to kill off the right.

I was trying to keep the pea at about "half full" on the fire brick but that doesn't seem to help. I have been loading it up on the "good" side to encourage airflow on the weak side. Seems like the fire is spreading now.

I hadn't thought of the Sam angle. It's a possibility. ;)

I agree with the guys. You need the air to get through the dead spot. Give her a couple of pokes through the bed of coal and ash and the strong fire on the one side should spread over to the problem side.

Yea these stoves need constant tending one way or the other. Depends on weather and how much your tending the stove. Generally a sure fix is I shake it good load a heap of coal and open it up..eventually it gets good again but then I may have too much heat.
