A gas water heater must be installed first, if it is a plaster-like ceiling. It is not recommended to install this kind of ceiling, any product will have maintenance and other services, and the closed ceiling is not convenient for future security inspection and maintenance.

Gas water heaters that can't catch fire can be divided into no ignition sound and no ignition and no ignition sound when there is a little fire. >>>More
There is an ignition condition for gas water heaters, that is, the ignition can only be triggered when the amount of water output (adjustable but not large) reaches a certain value. This should be the case when you encounter it, see how to deal with it, or turn down the temperature to reduce the amount of mixed cold water and increase the amount of hot water output, etc.;
After the gas water heater is started, the original cold water in the pipe must be discharged before the hot water can come out, and if the hot water pipe is relatively long, it will take four or five minutes for the hot water to come out.
