Important Guidelines
1
Do NOT cut or bend the thermocouple.
2
Keep thermocouple wires and the thick end of the thermo-
couple completely out of the firing chamber. Only the 1/8"
diameter tube should be inserted into a firebrick hole.
3
Keep the thermocouple wires from touching the hot kiln
case. The thermocouple itself must not touch anything metal-
lic during operation.
4
Even though protected by insulation, thermocouple wires
are sensitive to electromagnetic interference. Position the lead
wires away from electrical appliances and wires such as the
kiln cordset.
5
The thermocouple must protrude into the firing chamber at
least ½" to 5/8” for accurate readings. (Over 1” is not recom-
mended.) Keep the thermocouple at least ½” away from ware
or furniture.
6
Position the thermocouple hole approximately midway be-
tween the firing chamber floor and roof.
7
Before using your TnF 2, please read the digital controller
operating instructions.
Step 1: Position the TnF 2
Position the TnF 2 far enough away from your kiln to avoid
heat damage. If your TnF 2 uses a mercury relay, the TnF 2
must be wall-mounted so that it is vertical. TnF 2s that have
mechanical rather than mercury relays can hang vertically on a
wall or lie flat on a table.
How to tell if your TnF 2 has a mercury relay: If the TnF 2 is
placed horizontally on a table,the mercury relay will turn on
power to the kiln, even when the controller is idle. When the
TnF 2 is held upright, the power will shut back off.
Step 2: Attach the
thermocouple to the kiln
You can install the thermocouple (temperature sensor)
through an existing ½” thermocouple hole, through a drilled
peephole plug, or by drilling a new hole in the kiln.
