First, the product description: This product is a high thermal efficiency, energy saving a strong emission gas steam generator. Currently, the average restaurant, kitchen steam when needed, turn on the water in the pot are direct heating, steam is generated by burning heating, such a heating method, the thermal efficiency is very low, a great waste of energy. And this furnace structure using spiral flue, flue by immersion in water for water heating, greatly increasing the heat transfer area, improve the thermal efficiency, so as to achieve the purpose of energy conservation, this steamer normal temperature and pressure conditions set level By the time produce steam for 3-4 minutes, so this steamer, is for you to save operating costs and improve the efficiency of a good helper. The products of combustion using low pressure LPG family pack, not the use of other gas species. When in use, simply choose the appropriate tool to steam their products, this product technical parameters Power: 220V Motor power: 120W Weight: 25kg actual heat load: 20kw rated gas pressure: 2800Pa refrigerator volume: 45L Specifications: 500mmx700mm two methods of operation and a need for attention, the product family pack of ordinary low pressure liquefied petroleum gas, can be used only when you install Family Pack low pressure valves, prohibit the use of high-pressure valve. When connecting, make sure all the LPG pipe connecting the mouth sealed cylinders over at least two meters away from the furnace, when used, must not be upside down and side-mounted cylinders, in order to avoid overflow bottle residue, causing low pressure valve plug down, and the furnace body electromagnetic valve failure, low pressure will cause the valve plug down due to lack of pressure to reduce the fire and automatically turn off, bottles slag flow through the solenoid valve caused by failure will lead to extinction, and the solenoid valve is not fully closed after shutdown caused still burning at this time need to remove the valve and solenoid valve can be cleaned, if necessary, should be replaced. 2, to ensure a reliable ground use. 3, this product is no automatic inlet valve is recommended when using this device, the use of the need to ensure there is enough water pressure to avoid dry, automatic inlet valve needs its own regular checks to ensure the normal use. If the use of artificial water, the water level should be much higher than the tank fire tube position. Avoid dry, we should always observe the water level. 4, add water, ventilation, after turning on the power, the fire size knob to adjust the position of a large, open switch. At this point the fan start running empty, 2-3 seconds after ignition pulse start, begin normal operation of the overall operation. After closing the switch, the fan still operate normally 10-15 seconds, which aims to end the remaining exhaust gas discharge. So after the flame, For ignition should be completely stopped after the fan. 5, the machine is equipped with a microcomputer anti-dry device, when the water level drops below the set level, the machine is fully automatic shutdown, and sound an alarm. (Only a square fire tube furnace configuration, there is no anti-dry fire tube circular configuration, you must add automatic water tank.) Third, the failure and exclusion and inspection methods: 1, start switch is not activated. First check a reliable power supply, switching is normal use, the fan is normal, each cable is loose, if normal, replace the pulse. 2, after the start switch, fan rotation and no pulse, the pulse needs to be replaced. 3, after the start switch, there is no pulse and fan rotation, but no ignition, check valve and the solenoid valve for inverted plug, if necessary, can be removed for cleaning or replacement. 4, lit automatically turn off after a period of time, first check whether the vicious row within the fire from the fire sensor needle row too close or too far away, sensing needle end should be 4-5 mm away from the fire platoon, if normal, replace the solenoid valve while checking the wiring is normal. 5, there is no automatic water inlet valve, check for obstructions can be removed to clean themselves. 6, after a period of time, if there is deflagration. First check valve if there is a bottle of slag pour stopper, if there is a need to clean or replace. Also check whether the normal ventilation pipe, if this phenomenon is still need to replace the solenoid valve. Another check whether the fire row fumaroles have blocked debris.
