Our portable water heaters have a control system operated by water pressure. This includes the models L5, L10, EL5, EL7, EL10, CEL5 and CEL10.
This control system senses when there is a demand for hot water and activates the gas and ignition sequence. The system also senses when there is insufficient water pressure to operate without overheating. The operating water pressure range is 25-40psi. Water must maintain pressure between these ranges to operate properly. Fluctuations in water pressure can cause the water heater to shut off or overheat.
If your water heater is not igniting but you continue to hear it click, below are some things you can check.
1. Solenoid
Your gas solenoid may be stuck. This can be easily fixed by removing the cover of the heater and gently tapping on it. Please do not attempt to remove the solenoid. Below is a picture of the solenoid.
2. Wire Connections
The connection on the wire coming from the solenoid may have come loose. Simply disconnect and reconnect the connector.
3. Propane Tank Valve
The valve on your propane tank may not be open. Please verify that this valve is in the “Open,” position. You may also be out of gas. Please contact your propane provider.
4. Overfilled Propane Tank
Also, if you refilled your propane tank recently, it may have been overfilled. You will know this because when you try to operate the water heater, the regulator on the hose gets extremely cold. Follow up with the company that filled the tank.
