3.6 Test by Fire Mode
WARNING Fire Containment Lid and pivot shaft be kept clean to function
properly. Do the damper check before testing by fire mode.
As some fire may not be extinguished completely by the Fire
Containment Lid, the operator may have to extinguish the fire
manually. Prepare fire-resistant gloves and other necessary
objects to protect against burns.
Use knob when resetting the fire containment lid.
The following shows only differences from Normal mode. See Section
3.4.1
to

When the flash point is detected, the buzzer beeps and the RUN lamp flashes. At this point, test
flame application at the 2

START
switch while the

lamp is flashing will stop the buzzer, and the test is continued
until the fire point detection. If the

terminated and the cool down cycle is initiated.

Once flash detector detects 5 seconds of continuous burning (or press
START
