2. Range Hood: how to use and maintain?
        A. Power Outlet of Range Hood must use a reliable Outlet earth, which is the exclusive outlet;
        B. to install Range Hood in accordance with the specification, the general installation height should not be less than 650 mm, possible installation is above the top of the stove;
        C. to open Range Hood 1 -2 minutes before cooking, in order to obtain better results to remove soot;
        D. when replacing the lamp, power must not exceed lampholders nearby and the maximum on the label of brochures, otherwise, the rapid growth of temperature will appear in the connections of the wires and lampholders. Then wire insulation layer accelerated aging, which will result in the potential risk of electric shock, even result in a fire;
        E. when the oil dirty of the oil cup accumulates to 80%, please abandon it, so as to avoid overflow;

        (3) To use soft plastic brush to clean the dirt pass filter pores, and then use a dry rag to wipe off.
        (4) As the way one take down filter enclosures to install them as before.
        (5) After installation, please check whether the oil road of apparatus is smooth and the sealing gasket is in work.
        (6) To wash strainer, cover as the cycle in the brochure.
        I. Range Hood's internal electrical connections, and sealed part flow were not suitable for regularly demolition and wash. Demolition of seal is easy to bring aging and deformation, and oil dirty connected location, which will harm their safety performance and lower the life expectancy of Range Hood.

        2). dust reason: When there is dust in the house or when the water and oil gas in the air around increases, also it is prone to be red..
        3). wind-door reason: poor regulation in wind-door may result in this situation, then, can only regulate door.
        4). pan-support reason: Because the surface enamel of pan-support is becoming red in the high temperature heating, Due to the special ceramic material supporting, people will find that flame red when the pan-around, which is the color of metal ion under high temperature.
        Therefore, the redness in fire is not a problem of stoves, but because of the above reasons. It will not affect normal use, and will not harm people's health either.

5. In the event of gas stoves have failed to start fire, what to do?
        If a gas stove fire has failed to start fire, the following procedures shall be conducted: First, please check whether gas source switches is at “on” state, if the state is on, then Secondly, check whether there is a connecting hose collapsing or bending, if not collapsing or bending, then, finally, picked up the pot -support racks, see whether the nozzle spurs fire:
        1). if not spur fire, then see whether the discharge needle release a discharge, if not, that isa discharge needle fault, please replacing discharge needle. B, if yes, that is the valve failure, then the valve should be replaced.
        2). if it spurs fire: if it can have normal combustion, ignition note is in the higher the position. Then users will be guided that ignition should be gently turned down a few, and add pan-supported. B, if it spurs fire, but the flame was too weak and fail to get the furnace then the gas pressure is too low, so LNG users should focus on the replacement on valve, users of coal gas and natural gas should talk to the gas companies.
