Arrived today and tried it out to see what it heated to on my EX4, experienced a few problems along the way, which i think will need some modding due to the flames not going straight up the hole and some flames even escaping out the back or front (depending where I positioned on the Grate runners.
Tried the back tabs on the the actual grate runner at the back which left quite a bit of overhang on the front, at 360-380F the flames didn't seem to bad and most went up the hole but the stone never got higher than 450F, turned it up to 400f and the flames came out the back

Moved it to the slightly higher ledge at the back above the runner, same thing happened with temps as above but flames came out the front on occasions and the stone never went past 450F

Was out there 2 hours in all trying to get it right, moved it slightly left or right occasionally, but it still persisted, when I moved it further back could see what was happening in the burn pot and with the lid opened constantly the temp drops on occasions, the Smokefire tries to compensate by firing more pellets, but they build up towards the front of the burn pot and getting a raging fire when they finally ignite.
Hopefully a modded pipe down to the burn pot will control the flame better, so long as any escaped flame doesn't shoot up the pellet chute towards the augur.
If anyone has done a successful mod or can see where I've gone wrong be grateful for advice, can see it could work, just not ideal at the moment, hoped the stone would heat up more
Thank you for all the great information, I now know not to schedule a pizza party anytime soon. I’m looking forward to trying some things.
