The Kiln Sitter Cress Ceramic model LT-3K helps ceramic makers multi-task while making crafts. Once adequate time and temperature settings are tested and proven, the heat- and corrosion- resistant Kiln Sitter LT-3K can be used continually for error-free ceramic making. Although not fool-proof, the Kiln Sitter is designed to use heated cones or bars that will turn off a kiln before it over-fires. The LT-3K model also has a back-up electric lock that activates and turns a kiln off in the event that the heated cones fail.
Step 1
Maneuver the sensing rod in the middle of the Kiln Sitter LT-3K to check for free movement. Power off your kiln.

Step 2
Locate the metal cone support affixed to the firing gauge at the end of the tube on the model LT-3K. Apply a thin coat of kiln wash to the cone support and sensing rod. Wait until the kiln wash dries completely.
Step 3
Stack shelves and ware at least 1 inch below or above the Kiln Sitter LT-3K tube. The normal shut-off function should be fully visible. Ensure that you can also see the LT-3K's cone support above the kiln.
Step 4
Locate the weight extension on the front plate of the LT-3K. Lift it up against the rectangular guide plate on the front plate. The release claw is in the middle of the guide plate. Lightly press the claw down. This will engage the weight's trigger.
Step 5
Hold the trigger claw down. Simultaneously, flatten your firing cone or bar on the cone support. Align the inside edge of the cone's number circle with the outside edge of the cone support. The center of the cone or bar should be parallel with the end of the Kiln Sitter's tube. Proper placement will support the weight by keeping the trigger claw engaged without you holding it.
Step 6
Close your kiln.
Step 7
Set your limit timer knob to 15 to 30 minutes after the kiln firing time. As a safety shut-off device, the limit timer knob will keep your kiln from over-firing if the Kiln Sitter fails to turn off on its own.
Step 8
Allow your kiln to ventilate by removing the top peephole plug from your kiln. If you are using a large kiln, remove the bottom peephole plug as well.
Step 9
Put your index finger in the Kiln Sitter's weight hole and push the plunger firmly until it locks. Turn on your kiln.
Tip
Keeping your kiln off before turning on the Kiln Sitter LT-K3 will increase the life of the model.
If your sensing rod does not move freely in Step 1, contact the manufacturer for a tube assembly replacement.
Warning
If the sensing rod is corroded or contaminated, the Kiln Sitter LT-K3 may not shut off.
The sensing rod must be replaced if it is not moving freely, as it may cause inconsistent firings.
Improperly aligned cones or bars can cause over-firing that can damage both your wares and kiln.
