What parts should be checked before using condensing gas boiler

　　Before using the condensing gas boiler, check whether the pressure parts such as the furnace tube, furnace bladder, flue pipe, head and bracing are normal, whether there is serious corrosion, deformation, or cracking, and whether there is scale, impurities, or presence in the condensing gas boiler furnace Tools and objects are left inside. At the same time, make sure that no one is in the boiler before closing all manholes, hand holes, loading holes, and hand holes. When covering, the gland should be placed in the correct position, and asbestos should be placed between the hole and cover. Rubber ring or asbestos rope pad woven with asbestos rope. In order to prevent the mat from sticking to the hole cover or the edge of the hole after use, the two contact surfaces of the mat should be coated with a mixture of engine oil and black lead powder to prevent the use of white lead oil.

　　In addition to checking for damage to the exterior of the condensing gas boiler body, it is also necessary to check whether the heating surface and thermal insulation layer in the furnace are intact. Check whether there is residual fuel or soot in the furnace. Whether the chimney installation is reasonable. Check whether the position of the extinguisher device is reasonable, whether the extinguisher can be easily repaired, whether the heating pipeline is smooth and tight, whether the barometer indication is correct, whether the rotation of the fan and motor is correct, and whether the damper switch is sensitive. Whether the installation position of load conditioning is correct, whether the ignition electrode, ignition position, low fire position, and high fire position can be preset. The circulating pump has no water leakage, noise, and temperature rise during trial operation. The oil level in the bearing box is maintained to be normal, and the water inlet and outlet pipes are unblocked.

　　Test operation of condensing gas boiler water disposal equipment and deaerator, and check whether the boiler make-up water can reach the national request.
