Option A – In ConeFire Mode the Vent will turn on when you press start and will turn off when the kiln reaches 150 F (65 C). In Ramp/Hold Mode the controller will ask you if you want the vent on or off for each segment programmed. This is the same for all 3 options.
Option B – During a ConeFire Program the vent is on up to 1450 F (788 C) and then turns the vent back on during the cooling cycle at 1000 F (538 C) and stays on until the kiln reaches 150F (65 C). This setting for those people firing Crystal Glazes.
Option C – During ConeFire Mode the Vent stays off throughout the entire firing.
