Introduction: Electric water heaters, like ordinary household appliances, will more or less have some minor faults during use. Therefore, it is very necessary to master some maintenance knowledge and skills. Below I will explain to you how to install an electric water heater yourself and how to repair common problems with electric water heaters. How to install an electric water heater yourself? Principles:
1. Determine the installation location of the water heater in advance
Consumers should try their best to include water, electricity and other items related to the installation of the water heater during the home decoration stage. To do this, please ask the decoration company to lay the hot and cold water pipe lines of the gas water heater in place during construction. In this way, the installation cost of the gas water heater is basically limited to necessary items such as the flue (the part beyond the distance given by the manufacturer is borne by the user), bellows, figure-eight valve, etc. Generally, the material cost of this part is 300-500 yuan.
2. Pay attention to the route design of pipelines and avoid long detours
Consumers need to pay attention to whether the door-to-door installers have reasonable design of pipeline routes, and consciously avoid waste such as pipelines not running in straight lines and long detours. Material situation arises. If the kitchen and bathroom are far apart, and there are holes in the wall and re-routing of pipelines during construction, the initial installation cost may be higher, but the installation cost can also be saved. How to install an electric water heater by yourself? The whole process:
1. Unpack the water heater package
It is best to check whether the packaging of the water heater is intact and unopened when purchased, and whether it is damaged, etc. When unpacking, you need to check whether the accessories in the box are complete. For accessories in the water heater package, please refer to the water heater manual. In addition to the manual, expansion tube, and wood screws, there is also an elbow joint and a smoke pipe.
2. Pipe laying and valve installation
When laying out pipes, if the reserved holes are slightly smaller, it will be very difficult to intubate, so it is necessary to install pipes around the holes. Knock off a little bit so that the threaded pipe can penetrate smoothly. Before installing the hot and cold water valves, first completely close the water valves in your home to prevent water from flooding the mountain. Then install the hot water valve to the left in your direction and the cold water valve to the right.
3. Gas valve installation
When connecting the gas pipe of the water heater to the gas meter, a triangular valve needs to be installed to convert the gas pipe that was originally only for the stove into a gas pipe that can be used for the stove at the same time. and pipes for water heaters.
4. Setting up the smoke exhaust pipe
The smoke exhaust pipe is an important part of the gas water heater. If this link is not set up properly, it will have a great impact on the safety of future use. . It is best to arrange the flue pipe before the water heater is installed on the wall, otherwise the position will not be easy to adjust.
5. Preparation for drilling holes before installing the water heater on the wall
Determine the location, drill holes, and install expansion screws. After carefully measuring, first determine the upper position. After drilling the hole, hang the water heater first, then mark the position of the lower hole, and then use the drill to drill.
6. After the water heater is installed on the wall, final adjustments need to be made.
After the water heater is installed on the wall, final adjustments need to be made. The yellow hose on the outside of the threaded pipe needs to be cut off to maintain the appearance. After everything is installed, do the test run. How to install an electric water heater by yourself? Things to note:
1. Water heaters should be of high-quality brand products, and do not buy low-quality products and cause trouble for yourself. The gas source type and gas category specified on the water heater nameplate must be consistent with the gas source type and gas category used. Also pay attention to water pressure and gas supply. Everyone already knows that almost all gas instantaneous water heaters currently supplied at home and abroad are started by water pressure (or water differential pressure). However, due to current residence conditions, the water pressure in some residences cannot meet the requirements for starting water pressure, so you can purchase a Wanrong brand low water pressure (or water pressure-free) water heater. Sufficient gas supply is also one of the conditions to ensure the normal operation of gas water heaters.
2. When installing a gas water heater, the gas source type must be determined and the gas valve must be closed.
3. Gas water heaters can only be installed outdoors, on verandas, balconies, well-ventilated kitchens or non-residential rooms, but are strictly prohibited from being installed in bedrooms, basements, bathrooms (except for balanced water heaters), Near stairs and safety exits (not restricted beyond 5 meters), storage areas of flammable and explosive materials, rooms with corrosive media, wires and electrical equipment. The room where the water heater is installed should meet the following requirements: the height of the room should not be less than 2.4 meters. The room should have good natural ventilation conditions. The upper part of the outer wall or window of the room should be equipped with an exhaust fan or blinds (an exhaust fan is recommended). The lower part of the outer wall of the room should have an air inlet with an area of ??no less than 0.02 square meters. The exhaust fan should be installed in a place that is directly connected to the atmosphere, and the suction inlet of the exhaust fan should be higher than the water heater; the water heater must be installed in separate rooms (except for balanced water heaters), that is, install the water heater in one room and take a bath in another room. There should be no holes or small windows connecting the two rooms, and the two rooms can be separated by closing the door.
The room where a fashionable water heater is used cannot be connected to the bathroom and bedroom to form a large closed space, because using a water heater under such conditions is more dangerous, not only affecting the safety of the bather, but also affecting other people in the room, especially When the water heater is used continuously, if the environment is not well ventilated, it can easily cause a vicious accident in which a whole family is poisoned at the same time.
4. The installation height of the water heater should be such that the fire viewing hole of the water heater is at the same height as the human eye, generally 1.5 meters from the ground, and the distance between the smoke exhaust outlet and the ceiling should be greater than 600 mm;
< p>5. The water heater should be installed on a fire-resistant wall, and the clear distance from the wall should be greater than 20 mm. When installed on a non-fire-resistant wall, a heat insulation board should be added. Each side of the heat insulation board should be larger than the size of the water heater shell. 10 cm;6. The horizontal clear distance between the water heater and the gas meter and gas stove shall not be less than 300 mm;
7. There shall be no open electric wires, electrical equipment and flammable materials on the upper part of the water heater. The horizontal clear distance between the water heater and electrical equipment should be greater than 300 mm, and there should be a safe distance of no less than 200 mm around it; the water heater should not be sealed in a wall cabinet. If the water heater is installed in a wall cabinet or closet, it cannot provide sufficient combustion support. Air, the result is incomplete combustion, causing an increase in carbon monoxide in the waste gas, leading to poisoning accidents; secondly, the radiant heat generated when the water heater is working cannot be dissipated, affecting the service life of the water heater, and even a fire; sealing it in a wall cabinet will also It is inconvenient to maintain and repair gas water heaters. Gas pipes should be installed in the open. The gas pipes connected to the gas water heater should be galvanized pipes and should not be connected with rubber hoses.
