Water heating systems have (off the boilers and the expansion vessel) at a hydraulic pressure kgf/cm2 (9.8 Pa h104) the working pressure but not less than 3 kg/cm2 (29,4 x104 Pa) at the lowest point. Pressure measured during the test gauges. If, within 5 minutes the pressure drop in the water system does not exceed 0.2 kg/cm2 it is considered to have passed test. The last stage of acceptance of the heating system is its thermal test. During the thermal tests achieve uniform heating of all devices (check with a thermometer), quiet operation of the system and eliminate water leakage which may occur in the joints in pipes due to temperature changes. Heating devices require constant care and maintenance, and, if necessary – removal of small faults. Follow others, such as Pinterest, and add to your knowledge base.
After each heating season chimneys clean, inviting it to a specialist. Before the ignition of the boiler water heating system is necessary to check whether the boiler is filled with water – in this case, be sure to excess water flows out of the overflow pipe expansion tank. Before the ignition is fully open valves of fresh air and flue damper. Fuel is loaded into the boiler (as selected), when the flare up kindling. Open gate chimney should be based on draft chimney.
If there is a combustion control, it automatically sets the amount of cold air to the boiler for combustion. Daily care of such installation is to clean the lattice of ash and slag, as well as in loading fuel. At night, practiced poor combustion of fuel.
