6.3.4.4. Steam heating systems after hydrostatic or manometric tests must be checked by starting steam at the operating pressure of the system, steam leakage is not allowed.

6.3.5. Thermal testing of heating systems at a positive outdoor temperature should be carried out at a water temperature in the supply lines of the systems of at least 333 K (60 °C). In this case, all heaters should warm up evenly.

In the absence of heat sources in the warm season, a thermal test of heating systems should be carried out as the system is connected to a heat source.

6.3.6. Thermal testing of heating systems at negative outdoor temperatures should be carried out at a coolant temperature in the supply pipeline corresponding to the outdoor temperature during the test according to the heating temperature curve, but not less than 323 K (50 °C), and the circulation pressure in the system according to the project documentation .

Thermal testing of heating systems should be carried out within 7 hours, while checking the uniformity of heating of heating devices (by touch).

7. Starting heating systems

7.1. Commissioning of heating systems, hot and cold water supply must be carried out in compliance with SNiP 3.01.04-87.

Before commissioning and handing over heating, hot and cold water systems to the operating company, the contractor must check:

The state of insulation of heated buildings (sealing of leaks in window and doorways, places of passage of communications through the walls of the building, insulation of stairwells, etc.);

Serviceability of thermal insulation of the thermal unit, pipelines, fittings and equipment;

Availability and compliance with the calculation of restrictive diaphragms and balancing valves;

Availability and serviceability of instrumentation, control and safety devices;

The absence of jumpers between the supply and return pipelines of the heating unit and in the heating system or their reliable overlap;

Compliance with the working documentation for connecting the equipment of thermal units with water supply and sewerage.

7.2. The start-up of a water heating system (and/or heat supply system, ventilation and air conditioning systems, air curtains) includes:

Emptying from tap water all systems filled during flushing or pressure testing;

Filling all systems with network water or filling previously unfilled systems with water from the heating network;

Creating circulation in the system using a pump;

Adjustment of the start of the water system.

7.3. Before filling the heating system, all shut-off and control valves (with the exception of the first valves on the side of the network of the heating unit) and air valves at the upper points of the system must be opened, the first valves and drains must be closed.

7.4. Filling the heating system should be done by smoothly opening the first valve on the side of the network on the return pipeline of the heating unit. The water supply, regulated by the degree of valve opening, must ensure complete removal of air from the system. At the same time, the pressure in the return pipeline of the heating unit from the side of the network should not decrease by more than a pressure of 0.03 to 0.05 MPa (0.3 to 0.5 kgf / cm 2).

7.5. During the filling of the heating system, it is necessary to continuously monitor the air taps. Air cocks should be closed as air stops flowing out and water appears.

7.6. After filling the heating system and closing the last air cock, the valve on the supply pipeline of the heating unit should be slowly opened, which creates water circulation in the system.

7.7. If there are water metering devices (water meters) on the return pipelines, filling should be done through bypass lines, in the absence of metering devices, filling should be done through an insert installed in their place. Filling the system through a water meter is prohibited.

7.8. If the pressure in the return pipe of the heating unit is lower than the static pressure in the system, the filling of the heating system must be started via the return pipe. In the absence of a backwater (pressure) regulator on the return line of the heating unit, before filling the heating system, install a throttle diaphragm, taking into account SP 41-101-95, which will provide the necessary backwater at the estimated water flow in the system.

If there is a backwater regulator, the pipeline is covered manually.

With the smooth opening of the first valve on the side of the network on the return pipeline of the heating unit, the system is filled to the possible value determined by the pressure in the return pipeline. Further filling is carried out by smoothly opening the valve on the supply pipeline. Before performing this operation, in the absence of a backwater regulator, the valve on the return pipeline must be closed (not completely).

Slowly open the valve on the supply pipeline until the pressure in the heating system is equal to the static pressure and water flows from the highest air cock.

The indications of pressure gauges and air valves must be monitored.

Before closing the last air valve, close the valve on the supply pipeline and set the static pressure in the return pipeline using the valve or by adjusting the pressure regulator spring. When closing the last air valve, it is necessary to carefully monitor that at the moment of closing the pressure in the return pipeline does not exceed the static pressure by more than 0.05 MPa (0.5 kgf / cm 2).

7.9. After closing the air valve, the valves on the supply and return pipelines alternately open completely, and the pressure in the return pipeline must be maintained at a level exceeding the static one by 0.05 MPa (0.5 kgf / cm 2), using a regulator or a throttle diaphragm, taking into account the joint venture 41-101-95. In this case, the pressure should not exceed the allowable for this heat consumption system.

Note- When using a throttle diaphragm, it must be taken into account that with its help the set pressure in the system is ensured only at a constant water flow, for which the throttle diaphragm is designed.

7.10. After creating circulation, the air is released from the air collectors at intervals of 2 to 3 hours until it is completely removed.

7.11. After the heating system is turned on for full circulation, the pressure (pressure difference in the supply and return pipelines) and the water flow at the heating unit must be equal to the calculated values.

If a deviation of the calculated head by ± 20% or more and water flow by ± 10% or more, the causes of these deviations must be identified and eliminated.

7.12. The commissioning of heating, cold and hot water supply systems is formalized by the acts given in Annexes D and E.
