After the Chinese New Year holiday has ended, people returning to work have started to arrange various matters in the home. In particular, gas water heaters, if they are not properly installed and are not used for a long time, are prone to various minor problems such as: Ignition, water leaks, leaks, etc. Let us add more trouble on the day of rare rest.
So, how to maintain the gas water heater at home before leaving?
First, turn off the power, air supply
Some consumers returned home during a small long holiday and found a gas smell in their home. Not only that, when they bathed, the water was very hot. What happened? This was due to the fact that the water heater was not turned off in time before leaving home. Gas source.
Therefore, when the gas water heater is not used for a long time, for safety reasons, the power supply should be cut off.
In addition, there are many brands of water heaters on the market with gas detection systems, such as the double gas alarm system of Fangtai’s magnetized constant temperature water heater, if the harmful gas in the home is seriously exceeded (CO: ≥300ppm, CH4: ≥10%v/v (5000ppm)), the machine will report to 90/91, and push it to the mobile phone APP, send SMS, remind the user, let consumers use it more peace of mind.
Second, drainage
After the Spring Festival, the weather in many parts of our country is still very cold, but some consumers leave their homes before leaving home, the water storage of the water heater is not discharged, and when it comes back home again, the gas water heater in the home is often 'frozen'. The blisters broke the floor, and some even soaked downstairs.
In fact, the exhaust pipe nozzle of the gas water heater needs to extend outdoors. In winter, cold air will flow from the exhaust pipe into the water heater. When the temperature is lower than 0°C, the water in the heat exchanger tube will freeze. Expansion pipe fittings.
Therefore, the water in the gas water heater should be drained before leaving.
We can refer to the figure for drainage:
have to be aware of is:
1. After the water is finished, first turn on the hot water end of the faucet. At this time, the water should not be discharged. If water is discharged:
1) See if the current position of the faucet is in the direction of cold water, if yes, please go to the hot water direction;
2) The inlet valve of the gas water heater is turned off;
3) It is determined that no water will be available before proceeding to the next step.
Second, the water heater enters (or exits) the water outlet (where the water pipe and the water heater are connected). There is a screw on the side of the pipe. Turn it counterclockwise to open it. The water in the water heater pipe will flow out. Wait till the water does not turn out.
Third, there will be a rubber ring at the bottom of the screw, do not lose it or damage it (for sealing water).
In addition, regardless of whether the home is anti-freeze or non-freeze models need to be drained, because the anti-freeze model is the need for live work, the power supply should also be the same as the non-freeze model for drainage.
Third, clean
Many consumers barely clean the water heaters in their homes. Most of the water heaters in the home are installed in the kitchen. Over time, you will find that the keys on the surface of the water heater have failed. In fact, this is not a good job for cleaning.
In order to avoid this happening, the water heater should be cleaned and maintained in time.
During the Spring Festival, the home cooking frequency is high and the fumes are also large. After a long-term exposure to fumes, the machine surface will accumulate oil. If it is not cleaned in time, it will result in insensitive contact and cause the water heater's keys to malfunction. Therefore, we must perform the water heater in time. Cleaning and maintenance:
A. External cleaning
1) Wipe with a wet towel, but be careful not to use acidic, alkaline cleaners.
2) The outer layer of the gas water heater pipe is also very important for cleaning, but it must be ensured that the main valve of the gas pipeline is closed before cleaning.
3) When cleaning, do not use hot water and wipe directly with a damp cloth.
B. Internal cleaning
The external cleaning of the water heater can usually be handled by itself. However, internal cleaning needs to disassemble the water heater. It is recommended not to disassemble it. We must contact professional after-sales service personnel for cleaning. Therefore, we must also have a good after-sales service for all brands. Learn. If Futura Gas Water Heater will provide cleaning and maintenance services - After the water heater has been used for a certain amount of time, the machine display will show 'Maintenance'. At this time, you can call the service hotline and contact a professional service personnel to perform cleaning and maintenance services.
Fourth, check
Gas water heaters have been put on hold for a long time, and some consumers find it impossible to use them after they return home, such as: No fire, no hot water, etc. However, they do not know where the reasons are and they will have headaches.
Therefore, when using the water heater again, the water heater must be checked.
First, pipeline inspection
1) Check the pipeline for leaks (no further operations are performed);
2) Check if the gas supply pipe (rubber hose, main valve) is intact, has no aging, and cracks;
Method: After foaming with soapy water, spread evenly on the hose connection (the valve is the same). Observe whether any air bubbles appear. Determine if there is a leak. If there is a leak, you should try to stop or contact the maintenance personnel.
Second, the power check
1) Plug in the water heater power supply;
2) Turn on the water heater power switch to see if the water heater turns on normally;
Finally, turn on the faucet in your home and go to the hot water side to check if the water heater is normally started. If you do not start the switch first, try several times and try again. If you still can't open it normally, please look for the after-sales service personnel. Do not repair yourself.

Therefore, after the Spring Festival is over, we must properly arrange the gas water heaters in our homes so that the Spring Festival will have a more successful ending.
