There can be no power wires, electrical equipment and other flammable items above the gas water heater, and the horizontal distance between the water heater and the electrical equipment should be greater than meters.

According to the national standard, flue gas water heaters do not need to prevent incomplete combustion, but they must install smoke exhaust pipes to discharge exhaust gas outdoors to prevent carbon monoxide poisoning. The total height of the smoke pipe should be greater than 2 meters, the length of the horizontal section should be less than 3 meters, and the hood of the smoke pipe should be H-shaped, circular or oblique H-shaped to prevent the exhaust gas from backflowing.
