Doctor, how to reset the fan of the wall-hung boiler when C6 appears?

1. Causes of "C6" code of newly installed gas wall-hung boiler

The smoke pipe is not completely out of the wall or there is an obstacle above the smoke pipe.

The inner core of the smoke pipe is installed backwards. The smoke pipe is not installed according to Bosch standard, resulting in air leakage. Before the gas wall-hung boiler is turned off, the machine will have a "bang" abnormal sound.

Power cord socket is loose.

Solution:

The smoke pipe should be installed outside the wall according to the standard, and there should be no obstacles above the smoke pipe to ensure smooth air intake and exhaust, and the power cord plug should be pressed tightly.

2. The reason why the "C6" code appears in the wall-hung boiler that has been used for two or more heating seasons.

Outdoor dust enters the fan through the smoke pipe, resulting in too much dust in the fan over time, so that the fan speed can not reach the specified value, and the wind pressure switch can not be turned off.

Solution:

Remove the fan and fan hose and clean with cleaning agent.

3. The reason why "C6" code appears on the wall-hung boiler after rain and snow.

The flue installation of wall-hung boiler is not standardized, with high outside and low inside. Snow melting and rainwater enter the fan hose through the flue pipe, so that the wind pressure switch cannot be turned off.

Solution:

Reinstall the smoke pipe according to the standard of low outside and high inside, remove the fan hose, blow out the rainwater in the hose, and then press the "reset" button to make the wall-hung boiler run again.

Extended data:

1. Please read the instructions carefully and operate correctly as required before using the wall-hung boiler.

2, the use of wall-mounted boiler room must be well ventilated.

3. Regularly check whether the gas pipe of the wall-hung boiler leaks. The inspection method is to brush the pipe joint with soapy water. If bubbles appear, it proves that the gas pipe is leaking and needs maintenance.

4. Check the connecting hose of the wall-hung boiler, and replace it immediately if it is found to be aged and worn; The service life of the hose shall not exceed 18 months and the length shall not exceed 2m; When replacing a liquefied petroleum gas cylinder, whether the rubber ring at the interface between the pressure reducing valve and the cylinder falls off, ages or is damaged, and whether the pressure reducing valve is tightened, it is forbidden to twist it with tools such as pipe tongs.

5. When air leakage is found, immediately turn off the air source, remove the fire, do not start the exhaust fan and smoking machine, and open the doors and windows for ventilation and maintenance.

6. When using the wall-hung boiler, don't leave for a long time, so as to avoid air leakage and explosion caused by soup spilling or fire fighting by wind.
