Chapter Five — Maintenance

CAUTION: THE GASSES PRODUCED WHEN HEAT

TREATING REFRACTORY MODELS WILL DAMAGE

THE TRANSPARENCY OF THE QUARTZ TUBES IN

THE MUFFLE CHAMBER AND MAY CAUSE VACUUM

LEAKAGE. TO HELP EXTEND THE LIFE OF THE MUFFLE,

IT IS NECESSARY TO PREHEAT REFRACTORY MODELS

IN A BURNOUT FURNACE TO PREVENT THE GASSES

FROM DAMAGING THE QUARTZ GLASS IN THE

MUFFLE CHAMBER.

Cleaning Your Furnace

Your new furnace has been painted with an epoxy-based

paint and may be cleaned by using a soft cloth and kitchen

cleaners such as Fantastic

or Formula 409

. The front panel

should be cleaned with a window cleaner such as Windex

Never clean the display window with a dry cloth or tissue.

Always moisten the cleaning cloth with a cleaner such

as Windex

Chapter Four — Running a Program

To Start a Program:

1. Press the Program Select button.

2. Use numeric keypad to enter the desired program

number.

3. Press the Start Program button to begin the new

program.

To run the program currently on the two-digit display, simply

press the Start Program button.

When a program is finished, the four-digit display and the

Program Finish LED will flash and the furnace will play a tune

to let you know the program is finished. The furnace will

automatically cool down to idle temperature at this time.

The display will stop flashing and be ready for the next

input by pressing the Enter button.

The “program finished” tune can be customized to distinguish

one furnace from another. See Chapter IV — Special

Functions for details.

Replacing the Muffle

The FireLite furnace contains a muffle module designed for

simple service and replacement. The muffle module contains

the heating chamber and the thermocouple.

The replacement procedure is as follows:

1. Turn the power switch located at the rear of the furnace

to the off position. Remove the power cord from the wall

socket to prevent any chance of a shock hazard. Allow

the furnace to cool.

2. Remove the six Phillips-head screws holding the muffle

cover to the two upright brackets. Remove the muffle

cover by lifting it straight up until it clears the upright

brackets.

3. Remove the thermocouple connector from the column

by squeezing the two tabs and pulling away from the

column. Remove the heating element connector from

the bracket by squeezing the two tabs and pulling away

from the bracket. Remove the four large Phillips-head

screws on the top of the muffle. Grasp the handle on the

top of the muffle and lift vertically to remove the muffle

from the vacuum chamber.

4. Inspect the O-ring for damage and replace if required.

Clean the O-ring area and the sealing area of the new

muffle with a mild cleaning solution such as Windex

Lower the new muffle into the vacuum chamber with

the thermocouple and the heating element connectors.

These are keyed so it is not possible to plug them in

incorrectly.

5. Repeat step 3 in reverse order, reinstalling the muffle

screws and connectors.

6. Install the muffle cover by lowering it over the upright

column and aligning the screw holes. Install the six

Phillips-head screws that attach the muffle cover to the

upright column.

7. Plug the power cord back into the wall socket and turn

the power on. Observe that the temperature begins to

rise and stabilize at the entry temperature of the current

program.

8. Fire a chip of porcelain to test the firing temperature of

the new muffle. Adjust the calibration as described in

Chapter Four — Adjust Furnace Calibration to

Match Your Porcelain.
