Programming
Ramp/Hold is generally considered an advanced form of programming. It requires in-depth knowl-
edge of heatwork and a good feel for how your kiln performs under a range of conditions. Graph to
the left is an example of a simple glass fusing Ramp/Hold program.
Programming Cone Fire Mode
Step 1
From Idle Mode. Press CONE FIRE.
Display will read PRHT alternately with 00.00.
Step 2
Input a PREHEAT TIME IN HOURS AND MINUTES. Press ENTER.
Display will read CONE alternately with the last Cone Value entered. (See page 25 for more informa-
tion on Preheat.)
Step 3
I
nput a CONE VALUE. Press ENTER.
Display will read Spd alternately with the last Speed entered.
Step 4
Press a SPEED (SLOW, MED or FAST). Press ENTER.
Display will read HOLD alternately with a Hold time value.
Step 5
Input a HOLD TIME if one is desired. Press ENTER.
Display will briefly flash CPL, then will return to Idle Mode.
At this point the program is loaded and ready to start. Before pressing START, it is a good idea to
press REVIEW to make sure the program was input correctly.
Step 6
Prepare Venting
If your kiln is equipped with a downdraft vent, such as the EnviroVent2, you will want to turn it on be-
fore pressing START. Be sure the lid is closed (and latched if you have a Lid Lifter) and all the Peep
Plugs are in.
If your kiln is not equipped with a down-draft vent system, you will want to prop the lid open until
the chamber temperature reaches 1000 ˚F (538˚C), then close your lid. If your kiln is equipped with
a Lid Lifter, use the installed Lid Prop Latch. If your kiln does not have a built in Lid Prop Latch, use a
wedge of firebrick to prop it approximately 1 to 2 inches (2.5-5 cm). Always use fire proof gloves to
remove your prop. Leave the top peep plug out throughout the entire firing. Also, check to see the
area is clear of all combustible materials.
If your kiln has an EnviroLink, see programming instructions in the EnviroLink Manual.
Step 7
Press START.
Display will read -ON- briefly and then display the current temperature of the kiln and begin firing. If
a delay start has been entered, the display will begin counting down the delay time entered until it
reaches 0.00 and then begin firing.
