1/4 Pounder Posts: 90 Joined: June 11, 2016	Thanks for the responses. That helps me start to plan. Mine shipped today, so I should have it shortly. Are you running it around 20-30 PSI or something else?

1/4 Pounder Posts: 53 Joined: March 29, 2015	I am running 10-15 psi for 2 pounds at 45 degree ambient temp. I'm roasting just beyond first crack.

Burner section is 200mm dia x approx 1.8mm W.T. S/S pipe around 900mm long but Im sure it could be shorter without scorching. Crem ONE LFPP, Compak K10F, 6kg FB LPG/PID aArtisanQ_PID, UNO/LCDapter
