1. In order to prevent gas explosion accidents, the horizontal quick-install gas boiler needs to purge not only the boiler furnace and flue gas channel before starting, but also the gas supply pipeline. The purge medium for the gas supply pipeline is generally inert gas (such as nitrogen, carbon dioxide, etc.), while the purge medium for the boiler furnace and flue is air with a certain flow rate and velocity.
2. For gas boilers, if the fire fails to ignite once, the furnace flue must be purged again before the second ignition can be carried out.
3. During the combustion adjustment of the gas boiler, in order to ensure the combustion quality, the exhaust gas components must be tested to determine the excess air coefficient and incomplete combustion. Generally speaking, during the operation of the gas boiler, the carbon monoxide content should be less than 100ppm, and when operating at high load, the excess air coefficient should not exceed 1.1~1.2; under low load conditions, the excess air coefficient should not exceed 1.3.
4. In the absence of anti-corrosion or condensate collection measures at the tail of the boiler, gas boilers should try to avoid long-term operation under low load or low parameters.
5. For gas boilers burning liquid gas, special attention should be paid to the ventilation conditions of the boiler room. Because the weight of liquid gas is greater than that of air, in the event of a leak, it is very easy to cause liquid gas to condense and spread on the ground, causing a vicious explosion accident.
6. The boiler operator should always pay attention to the switch of the gas valve. The gas pipeline must not leak. If there is an abnormal situation, such as an abnormal smell in the boiler room, the burner cannot be turned on. The ventilation should be checked in time, the smell should be eliminated, and the valve should be checked. It can only be put into operation after it is normal.
7. The gas pressure should not be too high or too low, and should be operated within the set range. The specific parameters are provided by the boiler manufacturer. When the boiler has been running for a period of time and the gas pressure is found to be lower than the set value, the gas company should be contacted in time to check whether the gas supply pressure has changed. After the burner has been running for a period of time, the filter in the pipeline should be checked in time to see if it is clean. If the gas pressure drops a lot, there may be too many gas impurities and the filter is blocked. It should be removed and cleaned, and the filter element should be replaced if necessary.
8. After stopping for a period of time or checking the pipeline, when it is put into operation again, the vent valve should be opened and the gas should be vented for a period of time. The venting time should be determined according to the length of the pipeline and the type of gas. If the boiler is out of service for a long time, the main gas supply valve should be cut off and the vent valve should be closed.
9. The national regulations on gas should be observed. Fire should not be used at will in the boiler room, and electric welding, gas welding, etc. are strictly prohibited next to the gas pipeline.
