Features and Differences
From “inFire HTC” to “inFire HTC speed”
HTC speed = 90 minutes vs. 5-7 hrs.
Only 90 minutes needed
 to sinter a zirconium oxide substructure
Only 90 minutes needed
 to sinter a 5 unit bridge substructure
Only 90 minutes to sinter
 Full contour single unit/bridge
inFire HTC speed Furnace
What remains the same?
External design – only the name has been changed
Previous sintering programs still available
Ability to freely set sintering programs if desired
REF# is the same
inFire HTC speed Furnace
What kind of changes are there in the new inFire HTC speed?
Two additional fast sintering programs:
inCoris ZI speed in 90 minutes
VITA In-Ceram YZ speed in 90 minutes
Improved internal insulation
High performance heating elements
Eight additional drying and ventilation programs
For restorations which have been treated with staining liquids

Installation
inFire HTC speed- Installation Requirements
inFire HTC speed Basic Installation
- Connect Power Cord to NEMA 6-20 Outlet
- Turn on power switch
- Door will open
- SENSOR BROKEN error and loud beep due
to thermocouple not connected yet
- Turn power switch OFF
-
Remove packing material from inside the furnace
- Install door insulation
inFire HTC speed Basic Installation
inFire HTC speed Basic Installation
- Shown here on unit, do
assembly on table first
- Insert ceramic tubes
into holes in lower
door insulation block
inFire HTC speed Basic Installation
Insert the guide tubes into the upper door insulation block such that they
go in flush. Note that there are also 3 holes in the block that will fit onto the 3
tubes on the lower insulation.
inFire HTC speed Basic Installation
- Now attach the lower
and upper blocks together
by fitting the upper block
over the ceramic tubes. It
may be easiest to do this
by holding the blocks on
edge to keep the guide
tubes from falling out.
- Place the completed
insulation into the door
such that the open area
between the pins faces
forward.
inFire HTC speed Extended Installation
- To be performed by Patterson Technician ONLY
- Heating elements and wiring braids must be installed.
- Make
sure the bolts that secure the power cables to
the heater element braided cable are tight
- Thermocouple must be installed.
- Run Program 00 to test and calibrate the voltage.

Sintering Trays
Original Infire traysCANNOT be used on
speed cycles
Infire speed trayscan be used on ALL
cycles
inFire HTC speed Operation
Sintering Balls
DO NOT pour entire
contents into tray.
Use about 2 layers of
balls in the tray.
inFire HTC speed Operation
A tray can be loaded with up to about 25 units, depending on type.
Restorations must have room to move and not contact each other or the
side of the tray.
inFire HTC speed Operation

When using color or staining liquids, the
sintering balls will become stained. This can
discolor any non-stained restorations that are
sintered in this tray.
A separate sintering tray should be used for
stained restorations.

Programming Steps
S1-S4 buttons relate to
Step 1 – Step 4
Step 3 and Step 4 are
always used
For an unused stage,
enter 0 for Temperature
inFire HTC speed Operation
Programming Steps
-
Create a new program cycle
- Contact the material manufacturer for specifications
and recommended heating and duration values
- Make a programming chart with the desired values,
going in reverse order from top to bottom
inFire HTC speed Operation
Load an empty
program
Enter values from
chart, top to bottom
Use S4 key to step
through the fields
for Stage 4
inFire HTC speed Operation
Use S3 key to step
through Stage 3
entries
Press S3 again to
close the stage
Data entry is
complete
inFire HTC speed Operation
inFire HTC speed Operation
Press the Memory (Store)
Button to save the program
Enter a name for the
program if desired
Press the “F” button to
select a letter, then “S4”
to move to the next letter
inFire HTC speed Operation
When finished, press
S2 to confirm.
This is how the program
will display when it is
loaded. The name will
display while you are
entering the number, but
will go away when you
press S2 for YES.
inFire HTC speed Operation
Example of entering a “speed” program
In a speed cycle, the heating
velocity must be 30 C/min or
greater.
inFire HTC speed Operation
Using S4 to enter the
Stage 4 data
Continuing data entry
through Stage 2. Stage 1
can be left alone since
the temp is set at 0.
inFire HTC speed Operation
Save and name the
program as before.

CASTING TIME FUNCTION
To start a program with the
casting time function, press the
“Casting Time” button. Note that
the status changes to “AUTOST”
Use the S1 key to position the
cursor, and the numeric keys to
enter the day and desired
completion time. The start time
shown to the left will update.
Press START/STOP, the function
is now activated. To quit the
program, press the “Casting
Time” button again.

Additional Functions
inFire HTC speed Operation
Default Settings
By pressing the “F” button, the
following settings may be
changed. S2 sets the current day
and time.
“Lift temp” is the temperature at
which the door will open. 300 C is
the maximum setting.

Installation problems
If the thermocouple
wires are reversed,
there will be an error
regarding polarity.
The orange wire
must be connected
to the “+” terminal.
inFire HTC speed Support
Installation problems
If the door closes and
then opens again, the
upper door switch is
probably not being
actuated. This switch
may need to be
adjusted downward
slightly.
inFire HTC speed Support
Installation problems
If the door switch is
adjusted, you must
verify that the door
still fully closes.
inFire HTC speed Support
User Errors
COMPLAINT- “When I start
the oven, the door closes
but it never heats up.”
PROBLEM- The user thinks
that “START/STOP” is just
a label for the UP/DOWN
button and presses the
UP/DOWN by mistake. The
door closes but the status
never changes to RUN.
inFire HTC speed Support
Voltage Calibration
- The furnace controller assumes an average voltage of 230V
- When calculating the start time, the time may not be
accurate if the site voltage varies from 230V
- Load program 00 to run the correction program to correct
the values on the controller board for accurate calculations.
- The program takes 3-4 hours to run. If necessary, you can
stop it by pressing the Start/Stop key.
inFire HTC speed Support
Performance
- The restorations come out discolored
- This is NOT due to using a tray that is used for coloring
- Run program 00 with empty chamber
