1. Check the boiler appearance and gas pressure - when preparing to start up the gas-fired boiler, the stoker on duty should first do a comprehensive inspection, including the appearance of the boiler, valves and various connecting parts, and then check the gas pressure to ensure that the pressure value is within the normal range rather than too high or too low. After the inspection and confirmation, the gas supply can be opened Give the valve.

2、检查供水系统-燃气锅炉在燃烧的时候里面是要有水的，否则就会发生危险。所以，在启炉之前司炉工人应该检查供水系统，看水泵能不能上水，如果不能正常上水就要将放气阀打开放气，知道水泵能够开始上水为止，然后再打开供水系统中的各个阀门。

2. Check the water supply system - the gas-fired boiler should have water when it is burning, otherwise it will cause danger. Therefore, before starting the boiler, the stoker should check the water supply system to see if the water pump can supply water. If the water can not be supplied normally, the air release valve should be opened to vent until the water pump can start to fill water, and then open the valves in the water supply system.

3、检查水位-如果燃气锅炉里面的水太多或太少都会对锅炉的运行造成影响，在启炉之前做好水位计的检查非常重要，因为水位计的作用就是为了让司炉工能够随时了解目前锅炉里面还有多少水。

3. Check water level - if there is too much or too little water in the gas-fired boiler, it will affect the safe operation of the boiler. It is very important to check the water level gauge before starting the boiler, because the function of the water level gauge is to let the fireman know how much water there is in the boiler at any time.

所以，燃气锅炉启动前要看水位计的位置是否正常，而且还要看水位计的计位器和水位色塞是否处于打开的位置，以免出现假水位的现象，然后观察是否缺水。能够满足客户的燃气锅炉厂家告诉大家，以上就是燃气锅炉在启炉之前需要检查的事项，除了这些之外，司炉工人还要检查烟道上的挡风板并确保全部处于打开的状态。只有将锅炉的各个方面都认真检查好才能正式开始启动燃气锅炉。

Therefore, before the start-up of the gas-fired boiler, it is necessary to check whether the position of the water level gauge is normal, and whether the level indicator and water level color plug are in the open position, so as to avoid the phenomenon of false water level, and then observe whether there is water shortage. The gas-fired boiler manufacturers who can meet the customers tell us that the above are the items that need to be checked before starting the gas boiler. In addition to these, the firemen should also check the wind deflector on the flue and ensure that they are all in the open state. Only by carefully checking all aspects of the boiler can the gas-fired boiler be officially started.
