SETTING (either ° ° ° ° F or ° ° ° ° C), and 3) HOLD TIME FOR THE TEMPERATURE. You may also enter a DELAY to set the time you want the furnace to start the burnout program. All furnaces and controllers are warranted for one year against defects in workmanship or material. - Page 3 Grates and trays are sized to fit standard electric burnout furnaces. N0.

- Page 4 INSTALLATION PROCEDURES FOR WW ELECTRIC BURNOUT FURNACES 1) W13 and W14 Furnaces require 240V - 20 Amp dedicated power supply and a NEMA NO: 6-20 receptacle or you can wire in direct with a breaker box nearby (USE A LICENSED ELECTRICIAN).
- Page 5 AMPERAGE OF YOUR FURNACE. A LICENSED ELECTRICIAN SHOULD BE USED FOR ALL ELECTRICAL WORK. 3) Insert the thermocouple into the hole at the back of the furnace. If no hole has been provided, one must be drilled. CAUTION: DO NOT DRILL INTO HEATING ELEMENT. BE SURE THAT NO METAL IS IN CONTACT WITH THERMOCOUPLE METAL PARTS.
- Page 6 Place flasks sprue hole down. Do not allow flasks to touch the sides, back or door of the furnace, nor to touch each other's sides. Above all, do not allow a flask to touch the thermocouple sensor located in upper center of back wall.

Page 7: Programmer Display
PROGRAMMER DISPLAY The WW Computerized Programmer Display prompts the operator with various readings. The display may appear peculiar due to the construction of each character in the standard LED display. Reading that appear on the display and their descriptions are as follows. DISPLAY DESCRIPTION Abort The firing was stopped. - Page 8 Complete This means the firing completed as programmed. CPLT DELA Delay DELA is a timer that starts the kiln later. Delay time appears in hours and minutes. ˚F 1 Temperature This prompt which appears in Ramp-Hold programming, is asking for a target temperature.
- Page 9 PF 2 Power Failure The power failed. When power came back on, the temperature was below 212°F/100°C. Press [Abort}, then [Enter} to clear the display and return to “IdLE”. PF 3 Power Failure The power failed near the end of a firing. Power Failure There was a power failure during firing.

Page 10: Safety Rules
It is the operator's responsibility to make sure that the furnace turns off at the end of the firing. Follow the safety rules below in addition to the safety rules for your furnace. - Page 11 To prevent this from happening leave the ventilation holes open and occasionally run the Furnace up to it's maximum temperature of 1700 ° ° ° ° F (925 ° ° ° ° C). The carbon will burn off the elements.
- Page 12 PERMANENT PROGRAM NO. 2 [ 5Hr] This program operates the furnace for 1 hour at 300 ° ° ° ° F (150 ° ° ° ° C) and then advances slowly to 1350 ° ° ° ° F (730 ° ° ° ° C) over a period of approximately 2 hours, then holds that temperature for 1 hour.
- Page 13 Before you use this program, you must first eliminate the wax with either steam or utilize PROGRAM NO. 1. After the wax has been removed you may load the furnace SPRUE HOLE UP or use our WWT13 or WWT18 Grate & Tray and the sprue holes can remain down. REMOVE WAX TRAY AT END OF FIRST HOUR.
- Page 14 You can load your furnace at 3 - 4 or 5:00 P.M. in the evening and arrive at 7 - 8 or 9:00 A.M. and cast. Many casters prefer to load and cast in a 8 hour workday.
- Page 15 SEGMENT 2 We will then raise the furnace temperature to 1350 ° ° ° ° F (730 ° ° ° ° C) at a rate of 280 ° ° ° ° F (136 ° ° ° ° C) per hour (requires approximately 4 hours) and then hold at 1350 ° ° ° ° F for 2 hours.
- Page 16 3) The length of time that this rate should take. For example: If we want to heat a 300 ° ° ° ° F furnace to 1350 ° ° ° ° F over a 6 hour period, we would calculate as follows: ENDING TEMPERATURE (°...
- Page 17 0 ° ° ° ° F per hour indicates end of program This is the alarm temperature request This sets the alarm out of range (turns it off) If you wish you may enter a delay start at this time If no delay time, then the temperature inside the furnace.

3) To turn alarm off enter 9999. When the alarm sounds during firing, shut it off by pressing any key. If it sounds as soon as the furnace begins firing it is due to the fact that the alarm was set to 0000. -
Page 19: Power Failures
After a brief power failure during firing, [ PF ] will display, alternating with the temperature. Even though it displays [ PF ], the furnace will continue to fire normally. The display shows [ PF ] simply to notify you of a brief power failure.
