13. Turn on the electrical power.
14. Check the set-points parameters on the panel temperature controllers to ensure the proper
settings. The process chamber set point should be set at 250
0
F, which corresponds to the
first curing level. The process alarm (water mist) should be set at 50
0
F. The oxidizer
chamber set point should be set at the temperature specified by the local air pollution
control authority (generally between 1450
0
F - 1600
0
F). The oxidizer alarm (OTS mist)
should be set at 100
0
F.
Note: The process chamber’s 50
0
F alarm setting and the oxidizer chamber’s 100
0
F alarm
setting will activate the OTS mist system. These settings remain constant and will activate
above set-point values.
Example: Process chamber - 200
0
F set point---------OTS activates at 250
0
F
400
0
F set point---------OTS activates at 450
0
F
800
0
F set point---------OTS activates at 850
0
F
Oxidizer chamber - 1600
0
F set point--------OTS activates at 1700
0

15. With the oven doors open press the OTS test button located on the control panel to ensure
that the water nozzles mist properly. Hold the OTS button on and adjust the OTS valve
block water valve to the pressure indicated on the tag. Turn off the water supply. Water
is not required during the cure cycle.
16. Leave the oven doors open and start the oven by pressing the RUN/RESET button on the
programmable process controller. The burner firing sequence will start. The oven has a
purge cycle and a yellow jumper wire to bypass the oxidizer preheat cycle. The oven will
be purged with air equal to four times the system volume. The oxidizer and primary
burner pilots will then ignite.
Note: Normally the factory air damper setting is proper. The gas supply may be
adjusted if required.
17. After the purge the process burner will ignite. Look at the flame to ensure that it is either
contained in the firebox or flickering slightly from the heat ports.
18. If the flame is excessive, decrease the gas flow by the manual flow valve. Adjust the
valve by turning the black indicator. DO NOT LOOSEN THE NUT.
19. If the flame is a dirty yellow colour or is sooty, open the air damper slightly, a 1/4 turn at
a time.
