Fault Treatment
|
The phenomenon of malfunction |
Analysis of the causes |
Solution |
| The machine has no response after the heating starts up |
1.No power with electrical outlet
2.The plug doesn't work well
3.Functional switch is not set on heating place
|
|
Examine the condition of power service
Re-insert the plug
Adjust the functional switch in the right place |
| The noise is too loud when the heating system runs |
1.There is air block in the circulating-water system
2.There is dirt block in the circulating-water system
3.The tube of in the circulating-water system is too thin or too long
4.The fixed bolts of the machine aren't tight |
Examine whether the auto-delivery valve and air-escaped cap loosens or not
Other air-escaped valves discharges or not
Clean up the water-inflow filter web and systematic filter web
Enlarge the tube diameter and shorten the length of it
Firm the fixed bolts
|
|
| The revolving pump refutes during heating but no other response |
1.The temperature is set too low during heating
2.The of heating water system pressure
|
|
Increase the setting temperature of heating to a proper degree
Examine whether the system leaks or not Water-supplied door isn't shut tightly and causes to leak water |
| The air-blower rotates but no firing pulse |
1.The smoking tube blocks up
2.Pressure sebific duct has fallen down
|
|
Clean the smoking tube Re-install the falling tube |
| Firing pulse can be activated, but it's hard to fire |
1.The gas value hasn't been opened or hasn't been opened completely
2.The air in the gas-tube isn't discharged completely
|
|
Open all the gas valves
Restart the machine and discharge the air completely |
| The tempera age of heating water is too high |
1.The in the system causes air block
2.The air in the system causes dirt block |
Discharge the air in the system completely
Clean up the filer web and tube |
| The machine starts up frequently during heating |
1.The volume of circulating water flow is small |
Discharge the air in the system completely clean up the filter web |
| Some radiators becomes hot but others not |
1.There is air in the radiators
2.There is air in partial tube
3.The tube is too long or too thin |
Discharge the air completely
Enlarge the diameter and shorten length of tube as much as possible |
| There is no hot water flowing when is open during washing |
1.The volume of flow is smaller than the volume of flow when the machine starts
2.Gas valve isn't open |
Enlarge the volume of flow
Open the gas valve |
| The firepower often burns down automatically |
1.The volume of circulating water is small |
Discharge air block and dirt block |
| The gas boiler starts up frequently |
1.The volume of flow is small, difference in temperature is large
2.The radiator is forgotten to turn on after turned off
3.The filter web blocks up |
Decrease the resistance of system and thicken the circulating tube.
Open the valve on the radiator
Open up the dirt |
