The weather is getting warmer and it is in the peak season of spring home improvement. Every aspect of the decoration is very important. A small oversight can lead to partial or large-scale rework, so it is sloppy. For the installation of equipment in the kitchen and bathroom, I believe many of my friends are not very familiar with it. Especially the installation of water heaters.
Water heaters have become an indispensable appliance for every family. Like most kitchen and bathroom appliances, most of them are semi-finished products. You need to contact the factory's after-sales personnel to install them. However, some families think that installation is a simple matter and they can do it themselves. In fact, it is not! ! ! Here, we warmly remind you: the correct installation of the water heater, in addition to the requirements of the installation steps, but also the installation environment, installation accessories materials have strict requirements, otherwise it may bring certain security risks.
Gas water heater installation knowledge
When the gas water heater is installed, the gas connecting pipe must use the special rubber pipe for gas (the length should not be too long and the joint is fastened with the clamp), the stainless steel special gas pipe, and the gas valve should also use the gas special valve. The water connection pipe should use a pressure-resistant and temperature-resistant water pipe such as a PPR pipe and install a waterway control valve. The exhaust pipe must use a stainless steel exhaust pipe that matches the original machine.
installation steps
1. The water storage type water heater must be installed on the load-bearing wall, otherwise there is a safety hazard. If it is to be installed on a light-weight wall, it must be supported by a bracket underneath;
2, it is also skillful to drill on the tile. First, use a fine drill to grind a small eye to fix the eye position. Then use a thick drill bit to slowly dry the tile with a slow gear, and then use the impact file to drill deep into the hole. Will not be cracked;
3, drill a dozen, the screw is fixed, the next step is to hang up the gas water heater. At the same time of hanging, it is necessary to ensure that the water heater is firm and not loose;
4. After fixing the water heater, fix its hot and cold triangle valve. It should be noted that the outlet pipe (hot water) should not be installed with a valve, otherwise it will affect the amount of water and affect the function of use;
5, at the same time do not neglect the installation of small details, the installation of the exhaust pipe is also very important. The exhaust gas of the water heater must be discharged from the outside and the atmosphere, and should not be discharged to the public exhaust passage;
6. Next, it is necessary to select a suitable water pipe to connect the reserved hot and cold water pipes and the water heater. It is recommended to use PPR sanitary water pipes preferentially, and not to use water pipes that are not resistant to temperature, pressure, and aging;
7, followed by pressure test, air tightness and waterway inspection to ensure safe use.
8. After the installation is completed, it is necessary to test the machine, pass water, electricity, gas, test, and test whether the heating function of the water heater is normal;
9, the temperature of the water heater is generally 40 degrees is enough, the use of hot water should first test the water temperature by hand before the shower, to avoid burns.
Requirements for the installation environment
1. The place where the gas water heater is installed must have good supply and exhaust conditions;
2, gas water heaters can not be installed in the bedroom, basement, living room, bathroom (except smooth machine), cabinets, corridors and security exits (unlimited 5m), must be installed in a well-ventilated place;
3. The exhaust pipe shall not be installed in the ventilation duct or public flue of the building, and must be directly connected to the outdoor atmosphere;
4, the installation height of the gas water heater is generally about 1.6m, that is, the display is roughly the same height as the user's eyes;
5. The upper part of the gas water heater is not allowed to have electrical equipment and power lines, and the water heater and electrical equipment and gas meter should be kept at a sufficient distance;
6, the water heater should not be installed directly above the gas stove or other heat source, the horizontal distance should be greater than 1 meter or a larger horizontal distance depends on the actual situation, so as not to damage the water heater, or even cause a safety accident;
7. The tap water pressure is greater than 0.02 MPa, and the water flow rate is not less than 3 L/min to meet the start-up requirements of the gas water heater.
