Gas water heater exhaust pipe diameter

The diameter of the exhaust pipe of a general gas water heater is 60mm. The flue type is natural air convection, and the flue type smoke exhaust pipe is relatively large, generally100 mm. The smoke exhaust hole reserved by the construction party is a suitable 60mm smoke exhaust pipe, so the diameter of the smoke exhaust pipe of the gas water heater can only be less than or equal to ≤60mm. Generally speaking, the structural design of gas water heaters is as follows: the diameter of the exhaust pipe of gas water heaters larger than 10L (inclusive) is 60mm, and that of gas water heaters smaller than 8L (inclusive) is 50mm.

Data expansion:

The purpose of smoke exhaust pipeline is to exhaust indoor smoke to the outside through smoke exhaust machinery. Because flue gas often sticks to the pipeline, the flue gas pipeline needs to be cleaned frequently. Smoke exhaust pipes are widely used, including hotels and factories.

The purpose of smoke exhaust is to exhaust indoor smoke and dust to the outside through exhaust machinery, and ventilation can force indoor and outdoor air circulation through machinery. First of all, their ventilation direction and location are different, and second, the air quality they circulate is different, so they can't use the same pipe. Otherwise, if we accidentally bring smoke into the room during ventilation, it will be counterproductive. Finally, the installation standards of smoke exhaust pipe and exhaust pipe are different, and the smoke exhaust pipe system should be equipped with smoke exhaust and fire prevention.
