　　The natural gas boiler should be installed as close as possible to the place where heat is used and convenient for operation and installation. The hot water pipeline should not be too long and should have a good insulation layer. The pipeline should be inclined appropriately from the hot water output end to the end. The water supply source must be equipped with a control valve. If exhaust gas is to be discharged, the chimney of the natural gas boiler should extend to the outside, and the outlet should be 1.5-2M higher than the boiler.

　　The natural gas boiler power supply must be equipped with supporting control switches, fuses and reliable protective grounding wires, 380v three-phase four-wire extension (or three-phase five-wire extension), 220v single-phase power supply, wiring standards follow the power cord section standards in the attached table . All wiring must comply with relevant national regulations. When the water quality does not meet the requirements, use softened water equipment. It is strictly forbidden to use deep well water, which contains minerals and silt-rich water, especially in northern sandy soil areas and mountain forest areas.

　　The natural gas boiler power supply voltage must be controlled within 5%, otherwise it will affect the use effect. The 380v voltage must be three-phase five-wire power supply, and the neutral line cannot be connected wrongly. If the ground wire of the natural gas boiler is related to the safety of use, a reliable ground wire should be installed for this purpose. The ground wire should be piled nearby with a depth of ≥1.5m, and the ground wire cable connector should be sintered on the ground wire pile head. To prevent rust and moisture, the connected joint should be 100mm above the ground.
