Introduction
This manual covers the operation of the V6-CF series 700 kiln controller. The V6-CF is a
versatile controller that regulates the temperature in your kiln so you can fire a variety of products like
ceramics, glass, or jewelry. The experienced operator can go straight to the quick start guide. The novice
can learn more about different types of firing by reading the programming sections of the manual and the
ceramics and glass introductions on our web site www.bartinst.com .
In the following pages:
First Firing steps you through the initial firing for new kilns to “season” the elements.
Controller Front Panel is a visual table-of-contents for the function of each key on the face-plate.
Cone Fire is the quick, easy method of programming for ceramics.
Vary Fire (also known as ramp-hold) is the versatile programming method for writing your own profiles
for glass, jewelry and ceramics.
The other sections of the manual will answer questions about what to expect during a firing.
Precautions
The controller is used to control temperature; it is not a safety device.
Do not operate the controller in temperatures above 125oF.
Always supervise your kiln during a firing.
The controller contains electronic components which are sensitive to static electricity. Before handling the
controller dissipate any static charge you may have by touching metal or a screw on the controller panel, the
electrical box, the kiln lid, or some other grounded object.
Always check the position of the thermocouple probe before starting a firing. The current temperature
displayed on the controller is measured at the end of the thermocouple which must be in the firing chamber
about 1” to 1-1/2”. Seal the opening around the thermocouple with kaowool or similar material if
necessary.
Always review the current program (by pressing Review Program) before firing to ensure the correct profile
is programmed.
Ensure the kiln and the areas around the kiln are clear of combustible material. See kiln manufacture’s
recommendation on required clearances.

QUICK START
1. Read all precautions before using your controller.
2. Apply power to the kiln/controller
3. Clear the display and get to the idle mode by pressing ENTER.
4. Program the controller.
5. Review the program before firing to ensure the correct program is ready to fire.
6. Press Start. -On- will be displayed and then the kiln temperature. The relays and elements will be
cycled on and off to regulate the temperature according to the program.
7. At the end of the firing the controller will flash the current temperature, firing time, and CPLt.
Press ENTER to return to the IdLE state.
• IMPORTANT PROGRAMMING NOTE: Before initiating a firing profile or performing any
other function, the controller must be at IdLE. Pressing the ENTER key will clear the display of
errors (E-) or FAIL.
• In most cases when programming, you will choose an option, then press ENTER to accept the
option.
• With the display flashing IdLE alternating with the current temperature, you are ready to proceed
with programming.
• The CONE FIRE mode uses a patented method to achieve correct heat-work so it is ideal for firing
ceramics. The advantage of using the CONE FIRE method is that a very complicated firing profile
may be chosen with just a few key strokes. The CONE FIRE method helps protect against over
and under firing by carefully tracking and controlling the temperature at the end of the firing as the
cone temperature is approached. The final temperature is adjusted according to the final firing
rate. For example, as the heating elements age and the heating rate slows, the final temperature
will be adjusted downward to ensure the correct amount of heat-work.
• The VARY-FIRE mode can be used for ceramics, glass, jewelry, glazes, decals, etc. It allows you
to create your own firing profiles which can be saved and used over and over.
• If there is a kiln sitter on the kiln it must be set according to the manufacturer’s directions. Insert a
cone in the sitter that is one or two cones hotter than the controller setting.

5
First Firing of the Kiln
The purpose of the first firing is to put a protective oxide layer on the elements and thermocouple.
The first firing is done without ware in the kiln that might give off fumes that contaminate the elements.
This first firing should have shelves and witness cones. The witness cones should be on the middle of the
shelf nearest the center of the kiln. The programmed cone number should match the cones provided with
the kiln. Our example calls for a cone 04 firing but if your kiln is supplied with different cones, substitute
that cone number in the programming.
The first firing should be done according to the kiln manufacture’s specifications if they are different from
these instructions.
1. Apply power to the kiln/controller. The display will show WAIT, and then go to IdLE.
2. If the display shows PF press ENTER to proceed to the IdLE state.
Program the controller.
This example is for a Fast Glaze to cone 04 with no hold time at the end of firing.
Press Fast Glaze Display will show F-GL
Press ENTER Display will show CONE/xxx
Press 0 0
Press 4 04
Press ENTER Display will show HOLd/ 0.00
Press ENTER Display returns to IdLE/temp

Start the Firing.
Press start to begin the firing
The display will show –ON- then the current temperature. You will hear
clicking when the relays cycle power to the elements to regulate the
temperature. This firing will take around 6 to 7 hours.
End of firing
CPLT
At the end of the firing, the display will flash between
CPLT / Firing time / kiln temperature
Press ENTER to return to
IdLE
The display will now flash IdLE / kiln temperature. You may open the kiln
when the temperature has cooled to 150°F.
Review the Results
A properly bent cone indicates that the kiln is functioning properly and accurately. The tip of the
cone will be level with the top of the cone’s base when fired properly. The diagrams below will give you an
idea of a properly fired, under fired and over fired cone. Some variation from a proper bend is expected
and can be compensated for with the cone offset adjustment for each particular cone number based on test
firings.
Proper bend Under fired Over fired

8
CONE FIRE Programming
This is the quickest and easiest method to program the controller to fire ceramics. Programming
consists of choosing the firing speed and entering the clay or glaze’s cone number. The firing speed is
chosen by the type of firing and thickness of the clay. The bisque firings include water smoking and
carbon burn-out stages. The glaze speeds allow for faster firings. All 4 speeds will calculate the firing
rate at the end of a firing and adjust the final temperature for correct heat-work. Follow these few steps to
enter a cone fire program.
Press Slow Bisque Display shows
S-bC The slow bisque speed is used for thicker hand thrown ware. The slow speed gives extra time for release of water and carbon burn-out.
Typical firing times range from 13-17 hours depending on the cone #.
Hand built pieces may need a preheat stage.
OR
Fast Bisque Display shows F-bC The fast bisque speed is for thinner ware that requires less time for water smoking and carbon burn-out. Firing time is 9 – 11 hours,
typically, and depends on the cone number.
OR
Slow Glaze Display shows S-GL Slow glaze is used for firing glaze on thicker ware or for bisquing very thin ware. Typical firing time is 6-8 hours depending on the
cone number.
OR
Fast Glaze Display shows F-GL Fast glaze is the fastest speed and is used for glaze firing on thin ware, china paint firings, and decal firings. Firing times range from 4 to 5
hours
Press ENTER Display shows
CONE/xxx The displayed firing speed was accepted and now the controller is waiting for the cone number to be entered. The x’s represent the cone
number last selected.
Press Number keys for
cone number Display shows xxx Use the number keys to display a new cone number. Remember, cone numbers starting with a 0 are lower temperature than cone numbers
not starting with a 0. For example, don’t mistake a cone 6 for a cone
06!
Press ENTER Display shows
HOLd/0.00 The displayed cone number was accepted and now the controller is waiting for the hold time at the top temperature to be entered. Usually
this value is left at 0. If a time is entered the hours are to the left of
the decimal and the minutes to the right.
Press ENTER Programming complete
Display is back to Idle Zero hold was accepted and programming is complete.
NOTE - A preheat segment for drying (candling) ware can be added to any cone fire program. See
options section for PREHEAT instructions.
TEMPERTURE REACHED at the end of a cone fire program:
When the display is at IdLE, pressing Review Program, will show the heat-work adjusted temperature that
was reached. The temperature is displayed after oF in review program. This temperature will remain until
the controller is reprogrammed. Record this temperature in your log after each cone firing.

9
VARY-FIRE
The V6-CF has 6 vary-fire user programs to store and reuse. Each program has from 1 to 8 segments (2 to
16 segments if 16-S option is on). Each segment has a firing rate, a soak temperature, and a hold time.
Vary-Fire programming steps
1. Press “Enter Prog” to start Vary-Fire programming – the display will show USER/#
2. Select User number – Press a number key 1-6 then ENTER.
3. Enter number of segments – Press a number key 1-8 then ENTER
4. Enter the ramp rate for segment 1 – Type ramp rate then press ENTER. Rates of 1 thru
9999°F/hr are valid. See note for calculating ramp rate.
5. Enter the hold temperature for segment 1 – Type hold temperature then press ENTER.
Valid temperatures range from 1°F thru MAX kiln temperature.
6. Enter the hold time for segment 1 - Type hold time then press ENTER. Displayed time is
in the format hr.min. Left of decimal are hours, to the right of decimal are minutes.
7. Repeat steps 4 – 6 for each segment.
8. Enter an alarm temperature – Type an alarm temperature then press ENTER. See
OPTIONS section for more information on alarm temperature. The alarm set at 9999 is
turned off.

NOTES: For Vary-Fire programming
1. The first ramp rate of any user program must be an increasing ramp which means the segment
temperature must be greater than the starting kiln temperature.
2. To ramp up or down at the maximum rate, enter a rate of 9999.
3. To program a down ramp, you enter the rate/hour then a temperature below the previous
segment’s temperature.
4. It is best to write out the firing profile that you plan to program before you begin programming.
At the end of the Operation Manual there is a blank form for writing your firing programs.
Photo-copy as needed.
Calculating ramp rates for VARY Fire:
If you want to go from room temperature to 750oF in 3 hours, here is how to calculate the ramp rate. Take
the temperature that you want to go to (750oF) minus the starting temperature (70oF - approximate room
temperature) to get the number of degrees you want to increase in 3 hours (750 - 70 = 680). Divide this
number by the time you want to get to 750 to give you the ramp rate (680oF ÷3 hrs = 227oF/hr).
If you want to add another segment to go from 750oF to 1000oF in 4 hours, the same procedure is used.
Take the end temperature minus the starting temperature (1000 - 750 = 250) and divide this number by the
number of hours to reach 1000oF (250oF ÷4 hrs = 63oF/hr).

11
RECALL PROGRAM is used to recall a previously programmed firing profile.
Example: To recall user program #5, use the following:
Step Press Display Comment
1 RECALL
PROG Alternately flashing: USEr & 1 The controller is ready to accept the desired user number.
2 5 5 Indicates the user program selected.
3 ENTER Programming complete
Display is back to Idle User program #5 has been selected. . The current temperature then flashes in the display.
WRITE YOUR OWN CONE FIRE PROGRAM
Writing your own cone fire program combines the versatility of the Vary-Fire program and the
heat-work calculation of a cone fire program. It is a great way to get custom heating and cooling
rates and still have the controller do the heat-work calculation to get the correct cone bend
regardless of firing rate. The steps to write your own cone fire are the same as entering a Vary-Fire
program except when you are programming the top temperature press the CONE TABLE key and
enter the desired cone number then press ENTER. The cone number and cone temperature will be
displayed in the program review. The cone temperature can be entered into any segment so you
can also have cool down segments in the program.
Start the Firing
Press Start to begin the firing The display will show -ON- then the current temperature. You will here clicking when the relays cycle power to the elements to regulate the
temperature.

12
Operation of the Controller during a firing
The V6-CF controller eliminates much of the “babysitting” that is required with a manual kiln.
To ensure the most consistent results from one firing to the next, you should understand how the controller
operates and monitor the firing to ensure proper operation. The block diagram and flow chart show the
basic components of a kiln’s control system.

The block diagram and flow chart show that the kiln control system, in its simplest form, works
like your thermostat at home – when the temperature is too cool the heater comes on; when the
temperature is too hot the heater turns off. The major components of the control system are the V6-CF
controller, thermocouple temperature sensor, relay switch, power source and heating elements. The
controller is the brain of the operation; the controller adjusts the traveling set point according to your
program, reads the temperature in the kiln, cycles the relay on or off and determines when to end the
program.
The thermocouple (t/c) sensor is the first part to inspect when loading the kiln. The tip of the t/c
should protrude 1" to 2" into the firing chamber. Next, “START” is pressed, the controller reads the kiln
temperature and uses that temperature as a starting point for a traveling set-point (also called the local set-
point). The displayed temperature is the temperature inside the kiln. You should then hear the relay(s)
start cycling on and off to keep the temperature near the traveling set point. As the firing progresses the
controller moves the traveling set-point according to the programmed firing rate. The displayed
temperature should increase with the traveling set-point and the relay will be “on” longer. This sequence
continues until the final temperature is reached and the controller turns off the kiln. The display reads
“CPLT”.

END OF FIRING - CPLT
End of firing
At the end of the firing, the display will flash between
CPLT / Firing time / kiln temperature
Press ENTER to return to
IdLE
The display will now flash IdLE / kiln temperature. You may open the kiln
when the temperature has cooled to 150°F.
Review the Results
After a firing record the firing time, and load size. In your log keep any repair information. If
cones are placed in the kiln, record the amount of bending that took place.
A properly bent cone indicates that the kiln is functioning properly and accurately. The tip of the
cone will be level with the top of the cone’s base when fired properly. The diagrams below will give you
an idea of a properly fired, under fired and over fired cone. Some variation from a proper bend is
expected and can be compensated for with the cone offset adjustment for each particular cone number
based on test firings.
NOTE – An error code ( E- ) in the display indicates an abnormal end to a firing.
See the Error code section to help determine the reason for the
error code.
Proper bend Under fired Over fired

VIEW (information) SECTION
View Section - Contains buttons to look up cone temperatures, review programs, and view the
current segment. View Segment is also used to skip step during Vary-Fire Programs.
Cone Table- Used to look up the temperature of various cone numbers. The temperature that is
displayed is for self-supporting cones with a heating rate of 108oF/hr. To use, press Cone
Table, enter the cone number you want to look up, press ENTER; the cone temperature will
be displayed then the controller returns to IdLE.
Review Program - The information displayed when Review Program is pressed varies
depending on whether you are using Cone Fire or Vary Fire. When Review Program is
pressed, each of the steps in the current firing profile is displayed one after another
changing every ½ second.
In Cone Fire Mode - The display will show the selected firing profile in the following
order:
Display shows Description

16
In Vary Fire Mode - The display will show in the following order:
the user program # (USEr)
the number of segments (SEG)
1st ramp rate (rA 1)
1st segment temperature (oF 1)
1st hold time (HLd1)
(If there is more than 1 segment, then the ramp rate, segment temperature,
and hold time of each of the other segments will be displayed in order.)
delay time (dELA)
alarm setting (ALAr)
error codes on/off (ErCd)
View Segment - only functions when a firing is in progress. View segment is used to view the
current firing segment or to skip from the current segment to the next firing ramp. When
View Segment is pressed during a firing the following 4 items are displayed in this
order, the current segment of the firing, the calculated rate, the travelling set-point
(SETP, the traveling set-point should be near the current kiln temperature), and the
circuit board temperature. If View Segment is pressed during IdLE, StOP is displayed
then the current temperature.
Skip Step (SKIP) - Skip Step is included in View Segment. The skip step feature is only
available with VARY-FIRE programs. It is used when enough heat work has been done at
the current segment and you want to immediately go the next ramp rate. To skip to the
next ramp, press View Segment, then within ½ second, press ENTER, and ENTER a
second time. If you press View Segment and do not press ENTER within ½ second, the
current segment (e. g., rA1) will continue to be displayed. Simply wait until the
temperature is again displayed and press View Segment, then ENTER within ½ second,
and ENTER again. If you press View Segment, then ENTER, then decide not to skip to the
next ramp stage, simply do not press any key; after about 10 seconds the display will return
to the current temperature.

NOTE: In the vary fire mode, the first segment of user 6 must be an up ramp or the segment will be skipped.
In the cone-fire mode, a cone-fire program is connected to the vary-fire User 6 program. To combine a cone
fire program with User 6, first, program User 6 then program a cone fire. Next, activate the 16-segment option in
the Menu. This is a great way to add multiple cooling segments to a cone fire profile.
Important Note: In the cone-fire mode, the controller uses the first segment of user 6 to transition from the cone
fire program to User 6 so the first segment of User 6 is ignored by the controller. This means that when you
program the number of segments, you must enter 1 greater than the actual number of segments you need. You
then start the actual programming with segment number 2. The controller will ignore any information you enter
into segment 1 so as you program user 6 and the display shows RA 1, press ENTER, ENTER, ENTER to get to
RA 2.
NOTE: 16-S will appear in REVIEW PROGRAM if it is activated.
