The customized propane water heater does not work, mainly because its working conditions are not met, mainly for the following reasons:
1. Insufficient gas pressure
If the air supply pressure does not reach the required pressure range, the customized propane water heater will not work normally, and even the direct protection will not start. This is a safety precaution.

2. Insufficient water pressure
Whether the customized propane water heater can be started or not, the main switch is the water flow rate, which depends on the passage of enough water to start the combustion. When our water inlet pressure is insufficient, or the water inlet valve is not opened, not fully opened, or the water outlet valve is not fully opened, resulting in a small water flow, the customized propane water heater anti-dry function is activated and will not ignite.
3. Internal failure
The internal failure of the customized propane water heater will also lead to misfire, such as the most easily damaged water flow sensor, the failure of the air pressure switch, as well as the solenoid valve, proportional valve and other problems, as well as the failure of the control circuit and various water temperature sensors , will cause the customized propane water heater to not fire.
