FR 99 is the feed rate. When there is a + on there that just means that the stoker motor is currently on.
NOFIRE meant that the IGN setting in SETUP was set to M (manual) instead of N (none). N should be the setting you use since you do not have one of our igniters (not for sale anymore).
Your next step is to set you MIN and MAX values in SETUP menu to suggested defaults for your stove, 6 and 40. You get to SETUP menu by pressing and hold MENU button for 3 seconds or so, until the word SETUP displays. Then go on the MIN screen (tap MENU button until it shows up) and leave it there so the fire comes down to that setting (wait 30-40 minutes). Then adjust it a point at a time up or down as needed, with 15-20 minutes between adjustments, to dial it in for your particular stove. Then do the same for the MAX setting. For max you're aiming to have the fire full, but no burning coals falling off the grate. There should be 1-1.5 inches of ash at the end of the grate for full burn.
Fan speed (MANFAN) is adjusted by tapping the MENU button once from the round robin screens. It will display either FSM and a number or FSA. Use the Up and Down buttons to go one higher than 99 or one lower than 1 to set it to FSA (AUTO). Or continue to control the speed manually by adjusting the speed as you wish.
That should get you up and running reasonably well. If you continue to have problems write here, call the shop (315-299-3589) or email (firstname.lastname@example.org
