Does the exhaust pipe of the gas water heater lead to the ceiling or the wall? An exhaust pipe needs to be installed.

Many people use gas water heaters, which produce hot water very quickly and are very convenient to use. Gas water heaters are installed in general kitchens. In the process of installing the gas water heater, the exhaust pipe should be installed. The exhaust pipe of gas water heater is best installed on the ceiling or wall. We should choose according to the safety factor. Is it better to install the exhaust pipe of gas water heater on the ceiling or the wall? Look at the installation requirements by the way!

Installation requirements of exhaust pipe of gas water heater

1. There shall be no exposed wires and electrical equipment on the upper part of the water heater, and the horizontal clear distance between the side and the electrical equipment shall be greater than 30cm. If not, heat insulation measures should be taken. The distance between the water heater and combustible materials such as wooden doors and windows should be more than 20 cm. If this is not possible, flame retardant measures should be taken.

2. The gas water heater should be installed in a well-ventilated kitchen, a separate room or a well-ventilated aisle. Rooms with gas water heaters should be brick-concrete structures with windows communicating with the outside world. Room height should be greater than 2.5 meters.

3. Leak detection: After the connection is completed, it is necessary to detect whether there is air leakage. The easiest way is to apply it with soapy water, and it will be qualified without foaming.

4. The width of the space in front of the water heater should be greater than 80 cm, and the side wall should be greater than 10 cm. When installed on a non-refractory wall surface, the back of the wall should be padded with refractory material with a thickness of not less than 1 cm, and each side exceeds the shell 10 cm.

5. The threaded belt shall be wound for not less than 30 times, and there shall be no redundant belt plugging. The flat mouth of stainless steel bellows should be flat and the gasket connection should be fastened.

6. The installation height of the water heater should be around 150 cm. The inlet and outlet of gas water heater should be completely out of the wall. It is strictly prohibited to install in public flue.

7. Pipes laid along the kitchen cabinet or ceiling should not have joints. In other words, the underground pipeline is a whole, and there can be no joints in the middle. The Code for Design of Town Gas stipulates that all joints must leak.

There are two ways to connect the water heater: one is to walk along the ceiling, and the other is to walk along the kitchen cabinet to the water heater. The gas supply pipeline should use metal hose or aluminum-plastic composite pipe to transport gas, and the connection should be controlled by a separate ball valve.

9, after the connection of the pipeline should be horizontal flat vertical, appropriate position should be fixed.

Is it better to install the exhaust pipe of gas water heater on the ceiling or the wall?

If the exhaust pipe goes from the ceiling, the most direct benefit is beauty, and it will not expose the pipeline and affect the overall home improvement effect. Another key reason is that many residential properties are not allowed to make holes in the wall, so they can only take the public flue. Usually, public flue is divided into two kinds of flue, which solves the problem of easy smoke string. The master said, if you can make a hole from the wall, try to make a hole from the wall.

If it is a condensing gas water heater, its temperature can basically be controlled below 50 degrees Celsius, no problem, but if it is a constant temperature gas water heater, it is not recommended to go from the ceiling because the temperature is relatively high at this time.

The temperature of the pipeline will bake the ceiling for a long time, which will easily lead to the yellowing of the ceiling and the flue for a long time. Most importantly, if the kitchen ceiling is PVC ceiling, you can't walk from it. If you must walk from the ceiling, you should also do some corresponding treatment work. It is suggested that the pipeline be wrapped with asbestos first and then with tin foil, which can isolate the high temperature to some extent.
