FIRING
your furnace to begin firing at
in your studio, your furnace will have only one hour to
go before the firing is completed.
When programming a delay fIre for wax elimination,
you must be present to remove the wax before the
temperature rises above 3500 F. Otherwise you will ruin
your furnace!
You must be near the furnace near the end of a firing
to make sure the furnace turns off. If something goes
wrong and the furnace does not shut off at the end of the
firing, your furnace could be damaged or your ware
ruined. Overfire is not covered under warranty, no mat
ter what the circumstances.

To program a delay, begin the firing schedule with
segment two.

Set the temperature of segment two

How to Store More Than One Firing Schedule in
the SPPROG Program
You have 12 segments to work with. If you use fewer
than 12 segments for a firing, the remaining segments
can be used to store a different firing schedule. For
instance, if your first firing schedule uses only two
segments, you have ten segments left for other firing
schedules.
Let's say your firing schedule uses segments 1 and 2.

How to Tell if There Was a Power Failure
When you program a delay in firing, you will probably
be away from the furnace for much of the fIring. When
you come back to the furnace, how do you know if there
was a power failure? This is important, because
was a power failure, your ware may not have fired to
maturity.
Return to the furnace before
the firing program is to finish. If
the controller is in normal
temperature display when you
return, you had a power failure.
If there is a power failure
during a fIring, the controller
will exit from the firing program
and go back to the n ormal
temperature display. So

there was a power failure, or the firing schedule fired to
