Thanks for that. In the laser there are 4 burners at front right, through the floor. Flue outlet is most of back wall ca 3” high so bottom shelf can be set above it. is there a manual for this kiln? also, I’m new to this community. Is there a “notification “ or “search topics” function?

Hi - I have a laser J9 in UK and have been reading this thread to learn more about firing it. I raw glaze and fire to cone 03 in ca 13 hours at fastest but sometimes it can take 16 hours. I think this is a combination of inattentive regulation /kiln watching and setting. do you guys advise setting bottom shelf at a level above flue outlet and hard up against back wall, so that gases pass beneath the bottom shelf into the flue or, do you set bottom shelf low and clear of the flue outlet? I have seen it both ways. perhaps you set all shelves hard against back wall? I have seen that suggested. any advice welcomed.
