6 Flame Projector Firewall Operating manual 1. Note: please read and follow the safety instructions closely 2. Preface The Firewall is a propane gas driven flame projector, capable of emitting effect flames up to 1.3m high and 1.5m wide. Latest electronic safety and control systems allow operating the unit with the highest possible safety. The device is basically designed for in-door use; the use on outdoor stages is only possible if the unit is fully protected against precipitation, humidity, strong drafts and winds (also see safety instructions). Up to 12 Firewalls can be fired in parallel with only one control panel: the trigger signal can easily be looped through from burner to burner. 3. Components of the unit The unit consists of: Main control panel (multicontroller) Flame projector Firewall (effect burner) Gas hose with reducing valve Connecting cable 4. System functionality By switching the button to position I, an electromagnetic valve in the flame projector opens and releases propane gas into the flame lance. At the same time a highvoltage arc is generated in the head of the burner, igniting the expanded propane gas and emitting a flame column of up to 1.3m of height. The flame height can be adjusted with a reducing valve. A built-in flame monitor in the burner constantly controls the effect flame and immediately shuts of the gas supply if the ignition fails. The device will try to re-ignite if the flame extinguishes. 6

7 5. Installation of the unit with the multicontroller Flame projectors: start with installing the flame projectors. Ensure that there are no flammable materials in the safety area and make sure that nobody is in the safety area during operation (see safety instructions). The flame projectors shall be mounted on a horizontal, flat and fire-proof base. Flammable materials in the safety area must either be impregnated flame-retardant with appropriate agents or covered with fire-proof materials, so no ignition can occur. Dust accumulations above the flame, also outside the safety area, must be removed at all costs, as they can be stirred up by the flame and cause dust explosions. Keep in mind that the flames drift in winds or draft, probably necessitating a considerable increase of the safety distance. The device may only be operated on outdoor stages if a sufficient protection against the effects of weather, as heavy draft or winds, and precipitation (rain, snowfall, etc), is ensured. The flame projectors must be secured against dislocation or falling over. Perforated steel straps deliver a good performance in this task, they can be screwed easily and safely to the base. For the place of installation, select a location that is not exposed to impacts or strong vibrations. Propane bottles and hose lines: 11.4 kg bottles turned out to be ideal for the purpose, they can be obtained at outdoor equipment suppliers or specialty shops. The bottles must be set up on a site that is easily accessible, so it is ensured that they can be closed and removed quickly in case of emergency. The bottles must be placed in an upright (vertical) position on a stable and horizontal base, and secured against falling over. A steel chain, losely tightened around the bottle, delivers a good performance in practice; the loose tightening allows a quick removal of the bottle. There should be no rooms or hollow spaces below the installation site of the propane gas bottles. Propane is heavier than air and would collect in lower situated areas when leaking out, thus forming an explosive air/gas mixture. These rooms must be monitored with a gas detector (available as accessory) if this situation can not be avoided. Now check the included gas hose for visible damage. Cracked or damaged hoses or fittings must not be used; any defective equipment must be replaced immediately. If the hose is intact, connect it to the propane gas bottle by tightly screwing it on with an open-end wrench of proper size. CAUTION: LEFT-HAND THREAD Now connect the other end of the hose to the effect burner in the same manner, after removing the protective cap from the thread of the burner's connection. Ensure safe routing when installing the hose at all costs; it must not be exposed to the heat of the burner and mechanical or abrasive influences (e.g. kinking, running over by equipment) and must not present a tripping hazard. The hose must possibly be secured with a protective host duct. After the hose is connected, it must be checked for leak tightness: Open the propane bottle shortly and set the reducing valve to a pressure of 3 bar. Now close the bottle again. There must be no noticeable pressure loss after a holding time of 5 minutes. If necessary, the source of the leak must be detected with a leak spray or soap water (bubbling from the leakage) and eliminated. A leaky system must not be operated 7

8 Main control panel (multicontroller): set up the main control unit now. Choose a position from which the flame projectors can be directly observed at all time before setting up. Be sure to place the panel firmly on a stable surface where it is protected against the effects of weather and moisture. Open the cover of the device. Ensure that the EMERGENCY STOP BUTTON is not activated by gently pulling on it. Now lay out the control cable for the flame projector and make sure it is safely routed (also see gas hose installation). Now connect the controller and the burner with the control cable. Turn the male connectors clockwise into the jack until they snap in. You can use either one of the jacks of the burner (to remove the connectors, pull back the metal safety, turn the connector counter-clockwise and pull it off). Connect the power cable to a socket fused with 16 A (230 V). The unit is now ready. 6. Operating the unit with the multicontroller Open the valve(s) of the propane gas bottle(s) and set the desired pressure (0.5 bar to max 4.0 bar). Now insert the key into the key switch and turn it a little clockwise. The green "power" LED indicates presence of voltage. The flame of the Firewall will burn as long as you push and hold the button to position "I". ENSURE THAT THERE ARE NEITHER PERSONS NOR FLAMMABLE OBJECTS WITHIN THE SAFETY AREA OF THE BURNER WHEN TRIGGERING THE FLAME DURING OPERATION, THE PERSON TRIGGERING THE BURNERS MUST OBSERVE THEM AT ALL TIME NEVER FIRE THE BURNERS CONTINUOUSLY FOR MORE THAN 4 MINUTES DOING SO WILL IRREVERSIBLY DESTROY THEM ALLOW AT LEAST 30 MINUTES FOR COOLING DOWN THE BURNERS BEFORE FIRING THEM AGAIN If you wish to run multiple burners in parallel, simply loop the trigger signal through from burner to burner. Connect the controller to one of the burners. Now connect the control cable of the next burner to the 2 nd connector of the 1 st burner, the cable of the 3 rd burner to the jack of the 2 nd burner and so on. Up to 12 units can be operated simultaneously. 7. Shut-down Turn the unit off by first switching the button to position "0" and then turning off the key switch. Please note: depending on the selected gas pressure, the burner may still emit flames for up to 30 seconds. Pull out the key and keep it with you. The key should always be removed from the key switch to prevent unauthorized activation of the unit. Now close the valve(s) of the gas bottle(s). Then re-activate the unit as described above and depressurize it by pressing and holding the "I" button. An initial flame should very quickly (< 2 sec.) become smaller and eventually extinguish. If one or more burners are still emitting 8

9 flames for any length of time, the respective valves were not properly closed and the procedure must be repeated. The unit can now be turned off again with the key switch and disconnected from the power source. Disassembly can now begin in reverse order. Please keep in mind that the burners become very hot, do not dismount them before they have cooled off. Do not forget to put the protective caps back on the burner's threaded connectors. It is imperative that no dirt particles get into the gas inlet pipe CAUTION BURNERS MAY BECOME VERY HOT DO NOT TOUCH BEFORE THEY HAVE COMPLETELY COOLED DOWN 8. In case of emergency If serious malfunctions occur that pose a threat to persons and property, the device must immediately be shut down. Hit the EMERGENCY STOP BUTTON to do so. The unit then immediately shuts off the gas and power supply. Now immediately close the valves of the propane bottles. In case of a fire in the immediate area, remove the bottles from the site at once. 9. Care, maintenance and storage Dirt on the unit should be removed with a soft and moist cloth. Suck up sooting from the lattice of the burner head with a vacuum cleaner and wipe it clean with a cloth afterwards. Never try to clean the electrodes inside the burner head by inserting your hand or any other object Do not use aggressive cleaning agents. Maintenance of the device can only be carried out by the manufacturer. Maintenance must be carried out annually, please make an appointment with the manufacturer, or send the unit in. 10.
