Using the GM10F
Alternate Thermocouple Position
The GM10F thermocouple is positioned in the center of the kiln. This position gives the most accurate reading when the glass is located in the center of the kiln. If this thermocouple position is inconvenient for the work you are doing, it can be moved to an alternate location higher in the chamber. To do this perform the following steps:

1. Unplug the kiln.
2. Remove the back panel of the control box.
3. Remove the screws securing the thermocople block to the back wall and carefully slide the thermocouple out. Leave the thermocouple attached to the block.
4. Locate the alternate hole location and use the hole as a guide to drill a 1/4” hole through the brick for the thermocouple.
5. Slide the thermocouple into the hole and use a 3/32” drill bit to drill pilot holes for the screws that secure the block.
6. Attach the thermocouple block screws.
7. Stuff previous hole with fiber, replace the back panel and plug in the kiln.

Be sure to test fire the kiln after relocating the thermocouple. The temperature reading at the top of the chamber may be slightly different and therefore you may want to adjust your firing programs to compensate for the difference.

Bead Making Tips

If you have the GM10F but do not have the bead door we highly suggest you order this option for annealing beads. The bead door is designed to allow you to insert flameworked glass beads on a mandrel conveniently and without losing much heat out of the kiln.

The first step is to program your kiln to heat up to working temperature. This should take about 20 to 30 minutes. Below is a sample 2 segment bead program that can be entered in the Ramp/Hold mode on the controller.

To insert the mandrel just lift the door handle with your free hand and place the bead end of the mandrel through the bead opening. The kiln should already be on and at the suggested temperature. Rest one end of the mandrel on a shelf post and the other end on the ledge of the bead opening. Be sure that the bead is not touching other beads or the post.

When you lower the door there will be a gap between the bottom of the door and the ledge. This is normal and will not cause any problems. If you would like to make the gap smaller when you are fusing just add more fiber strips until you get a good seal.

When you are done working with the torch you will want to press “ANNEAL NOW” on the controller. This will advance the kiln program to the annealing schedule you have programmed. When it is done with the programmed annealing cycle the kiln
