Gas water heater installation, flue from the ceiling, what installation details need to be paid atte

Gas water heater installation, flue from the ceiling, are there any installation details that need to be paid attention to are as follows:

Since fixing the gas water heater needs to be nailed in the wall, you should deliberately avoid the nailing place where the water heater needs to be fixed in the future when running the pipe. Similarly, the circuit routing of the socket reserved for gas water heaters should also avoid the nailing.

Today's gas water heaters are all strong exhaust type, which needs to be exhausted to the outside, and this gas generally has a certain temperature, so the exhaust pipe of the gas water heater is metal. In the future, this metal exhaust pipe also has temperature, so the installation of this exhaust pipe should pay attention to avoid the exhaust pipe of the range hood that is generally in the ceiling, because the exhaust pipe of the range hood is plastic, and it is easy to age and damage when heated locally for a long time.

Gas water heaters cannot be installed in bathrooms. The water heater must be installed in a well-ventilated and easily accessible place.

Gas water heater refers to a gas appliance that uses gas as fuel to transfer heat to the cold water flowing through the heat exchanger through combustion heating to achieve the purpose of preparing hot water. It is mainly composed of valve body assembly, main burner, small fire burner, heat exchanger, safety device, etc. It also includes the flue of flue water heater and the strong exhaust device of strong exhaust water heater.

The basic working principle of the gas water heater is that the cold water enters the water heater, flows through the water-gas linkage valve body, and under the action of a certain pressure difference of the flowing water, the water-gas linkage valve is pushed, and at the same time, the DC power supply micro switch is pushed to turn on the power supply and start the pulse igniter. Gas water heaters are highly regarded by users because of their characteristics of instant on-the-flying, no need to wait, and small footprint.

1.Punching: Before punching, the master should first take a measurement, and then punch the hole on the wall according to the measured data.

The storage water heater must be installed on the load-bearing wall, otherwise there are potential safety hazards, if it has to be installed on the light wall, it must be installed below the bracket or other treatment. It is also a skill to drill holes in the tiles, first use a fine drill bit to grind a small hole to fix the hole position, and then use a thick drill bit to slowly grind the tiles through with a slow gear, and then use the impact gear to drill the hole deeply, so that the general tile will not crack.

2.Hang the gas water heater: drill a dozen, fix the screws, and then hang the gas water heater.

At the same time, it is necessary to ensure that the water heater is firm and not loose. The installation height is generally 165 175 cm, and the fire window is parallel to the person's line of sight. After fixing the water heater, it is necessary to fix its hot and cold triangle valves.

It should be noted that the outlet pipe (hot water) should not be equipped with a valve, otherwise it will affect the water output and affect the use function.

3.Exhaust pipe and threaded pipe installation: connect the reserved cold water pipe to the water heater.

To choose the right water pipe to connect the reserved cold water pipe with the water heater, you can generally use a special metal hose and choose a water pipe that is not easy to age. At the same time, don't ignore the installation of small details, the installation of exhaust pipes and threaded pipes is equally important. The exhaust gas exhaust hole of the water heater should be opened separately, and the public exhaust hole should not be used.

After the installation is completed, the overall test should be carried out, and the gas should be turned on, the electricity should be turned on, and the test should be carried out to test the heating function of the water heater and whether the water pipe is leaking. After that, it is necessary to test the pressure and carry out the compactness test to ensure the safety of use.

Note: 1. It stands to reason that the flue of the water heater cannot go from the ceiling, because it is unsafe, and the insecurity is mainly manifested in two aspects, the first is that the carbon monoxide produced by the insufficient combustion of the water heater may leak to the ceiling, and the second is that the water heater is in use, the flue will be very hot, and there are sparks flying out.

2. If it must be safe, pay attention to the sealing of the pipeline, and pay attention to the end of the gas outlet must be shorter than the end of the water heater, which can effectively prevent the condensate from flowing back into the body.

I'm doing this, I'll tell you about it, first of all, I'm the dry energy rate, I don't know about others, the flue length is not a problem, it is recommended that you choose a condenser, because the condenser adds a two-stage heat exchanger on the basis of the existing gas water heater, and the exhaust gas generated by combustion goes through the two-stage exchanger, and the temperature is about 50 degrees after heat exchange, like the situation said upstairs, it is the earliest old machine, and the current technology is not to use the condenser, you take the flue, as long as you decorate the wooden square inside the gusset plate, and the distance from his flue is more than 5cm, it is safe After a long time, there will be a little yellow, but there is no problem with safety, and then when you install the water heater, there will definitely be a joint in such a long pipe You ask the installer to wrap the joint with sticky tin foil so that it will not leak in the room no matter how high the temperature of the combustion of the exhaust gas is now a patent for the smoke exhaust pipe of the gas water heater, which is very safe to prevent strong wind and rainwater backflow If you are not at ease, spend more money Buy a condenser When installing, the joint is wound with tin foil to be well Adopt it at all!

1. First of all, read the "product-related installation instructions" carefully to have a rational understanding in your mind. 2. The "exhaust pipe" of the gas water heater should be made of stainless steel. 3. The fewer joints, the better, the shorter the total length, the better, the total length is less than 10 meters (the jargon is 2 meters and 3 curves, a bend is equivalent to 2 meters,) the vertical pipe should not be higher than 2 meters, and the air outlet should be lower than the horizontal pipe (slope 5%).

Each joint should be wrapped with heat-resistant "acetate tape". 4. In the process of using the gas water heater, properly open the window that can communicate with the atmosphere at the place where the water heater is installed. Just pay attention to the above points and you'll be fine.

The installation of the plumbing of the "water heater" with condensing technology is exactly the same. Theoretically speaking, "water heaters with condensation technology" have energy saving and reduce the exhaust temperature, but they are of little significance to household use and are the "selling point" of manufacturers. Acetate tape is highly resistant to pulling, and it is best not to use "tin foil tape" to tear nails.
