AIR BLEEDING FROM BOILER AND WATER HEATER
During the water heater system filling particular attention must be payed to the air bleeding.
Operate as follows:
-
Make sure that the manual and automatic air bleed valves are open;
- Turn the unidirectional valve spring exclusion screw (exploded reference) to horizontal position (perpendicular
to the water flow);
- Make sure that the main switch is off;
- Fill by turning the loading tap and making water flow in very slowly;
- Close the manual valves as they start pouring water in a sequence;
- When the manometer shows the desired pressure (0.3
÷
0.5 bar above the plant hydrostatic pressure),
close the loading tap;
- Ignite the boiler to Summer position and let the hot water circulator operate for some minutes;
- Stop the circulator, turning the main switch, and make sure that only water flows from the manual air bleed
valves. If air is released, repeat the operation;
- Turn the unidirectional valve spring exclusion screw (exploded reference) to the initial position (parallel to
the water flow);
- Check the pressure on the manometer again.
