2.2.2 “Auto-operation”
The instructor will operate the M-Fire by pressing and holding the “start” button for a while.
The M-Fire will automatically ignite the gas by electrical igniters; a specific cycle will be started
(depended by ‘selection’ switch).
Before ignition you will hear an acoustic signal; 4 beeps in 2.5 seconds.
Selector switch in position:
A: Increasing Fire:
The M-Fire will start with the low pointed flame. After 20 seconds the tray will ignite. After another 10
seconds the tray and high pointed flame join. If the tray is not ignited after 10 seconds, the ignition
stops and the Fail LED starts flashing slowly. After extinguishing (either detected by sensors or by
releasing the start button), the gas supply stops, and, an audible signal is emitted (a long beep of
approx. 1.5 seconds). After 5 seconds the M-Fire will be ready for use again. Maximum period of time
for this cycle is 60 seconds.
B. Re-ignition:
Fire: main burner and low pointed flame will burn for a maximum period of time of 60 seconds. If the
burner is not ignited after 10 seconds, the ignition stops and the Fail LED starts flashing slowly.
When extinguishing is detected, the gas supply will be reduced within the following 60 seconds. No
acoustic signal will be produced. After 2 seconds the fire increases. This cycle occurs a maximum of
two times.
When no there is no re-ignition after 5 seconds, the fire is put out sufficiently. The gas supply and
ignition are stopped, and, an acoustic signal is displayed. After 5 seconds the M-Fire is ready for use
again.
C. Intermittent:
The pointed flame will switch from high-pointed to low-pointed each time (2 seconds) and over a
period of time of maximum 60 seconds. If the burner is not ignited after 10 seconds, the ignition stops
and the Fail LED starts flashing slowly. After extinguishing (either detected by sensors or by releasing
the start button), the gas supply stops, and, an audible signal is emitted (a long beep of approx. 1.5
seconds). After 5 seconds the M-Fire will be ready for use again.
When “Auto-operation” is selected the cycle can be stopped any time by releasing the “start” button.
After a certain cycle (extinguishing observed by detectors or after releasing the “start” button in Manual
operation) the gas supply will be shut off and an acoustic signal will be audible (long beep 1.5 seconds).
This signal is a “Safe” signal.
When using the closed attachment plate only the point flames will work.
In case of an emergency the system can be shut off by switching the switch “Off-Hand-Auto” to “Off” or
by closing the valve on top of the gas bottle.
Always close the gas bottle after use.
2.3 Transport
Ensure yourself the gas bottle is closed. Disconnect the gas hose from the operating unit. We advise to
transport the gas bottle separate from the M-Fire, if possible. The operating unit and the control unit are
provided with wheels and handles to make transport easier.
