Cress FX - Kiln Sitter Adjustments; Kiln Sitter Operation

Kiln Sitter
® Operation
1. Check Kiln Sitter
® adjustments.
2. Turn all switched to “off” position.
3. Remove firing gauge and store. Serious damage to the kiln and the Kiln Sitter
® will result if
the kiln is fired with its gauge in place on the refractory tune.
4. Apply a thin coat of high fire kiln wash to the top edges of the metal cone supports and the
lower side of the actuating rod being careful not to apply any in the slot of the refractory tube.
Warning: remove kiln wash from the actuating rod and cone supports and recoat with high
fire kiln wash before each firing. Failure to do this will cause the cone to stick to the metal
parts (when the cone softens at high heat) and will cause overfiring.
5. Lift the weight up and press down on the release claw to hold it up in position.
6. While holding the release claw down with one hand, place a small cone (1 1/8” long) under
the actuating rod using your other hand. Be careful not to knock any kiln wash off the metal
parts while inserting the cone. The cone should be resting with a flat side down on the cone
supports.
[Insert FIGURE 3-5 INSERTING SMALL CONE]
WARNING
Keep the cone away from the refractory tube. If the cone touches the tube during firing, it
will stick to it and cause over firing.
7. When loading, keep shelves and objects at least ½” from the tube, cone supports, cone and
actuating rod (interior of kiln), also keep the area around the kiln and Kiln Sitter
® (exterior)
clear of all objects. Nothing must interfere with the weight when it falls or the kiln will
overfire. Set limit timer pointer to desired time.
8. Push plunger in so that it remains locked in. The indicator pointer on the limit timer must be
above the “off” position to allow the button lock to engage.
9. FIRE WARE CHECKING LARGE PYROMETRIC CONES BEHIND PEEPHOLES. (SEE
METHODS OF TEMPERATURE INDICATION PAGE 7-1) DO NOT USE KILN
SITTER
® AS AN AUTOMATIC SHUT OFF BUT ONLY AS AN AID TO REPEATABLE
FIRING. A PYROMETER IS USEFUL TO CHECK ON FIRING PROGREESS
(OPTIONAL).
10. TURN TIMER “OFF” MAKING SURE THE PILOT LIGHT GOES OUT. MAKE SURE
THE KILN SITTER
® BUTTON POPS OUT AND TURN THE THUMBWHEEL TO “▲”
AND THE SPEED CONTROL TO “MANUAL.” UNPLUG THE KILN IF THE KILN
WILL NOT BE USED FOR LONG PERIODS OF TIME. UNPLUG CORD CAREFULLY:
DO NOT PULL OR TUG CORD TO UNPLUG: GRASP MOLDED CAP ONLY WHILE
UNPLUGGING.
