If it is not a digression, it is better to leave a gap between the exhaust pipe of the gas water heater and the ceiling. The tight fit is good-looking, but there are minor problems in terms of heat dissipation and safety.
If it is a position on the cabinet or ceiling to give way to the water heater, let the after-sales service of the water heater come to your door first to design and explain the location and size of the holes. >>>More
Reserve enough space, the opening should be larger than the smoke pipe, and the inside of the ceiling should also be vacant, and the smoke pipe will become hot due to the heat of the high temperature exhaust gas in the use of the water heater.
Safe, but you need to buy a gas water heater with a strong discharge or balanced type. The exhaust gas generated is discharged outdoors with the smoke exhaust pipe.
It is possible to install it on an open balcony, but it is not sheltered from the wind. Blowing strong winds may have a little effect.
Gas water heaters are forbidden to be used without smoke pipes, unless they are installed on balconies.
