1. The portable tankless water heater requires a minimum of about .75 GPM and a minimum of about 25 PSI.

Note: water pressure is at the lower end of operating parameters. You will need a sustained water pressure of approximately 25 – 60 PSI for adequate use if you are using a 12/18/120 volt pump. See adjustment in previous section.

2. High Wind: for safety reasons the tankless heater will not start in sustained wind. Find an alternate location for the tankless water heater.

3. Out of, or low on gas. Propane gas cylinders sometimes are contaminated with air. Especially new tanks upon their first filling. Cycle the portable tankless water heater on and off by letting water run through the L5 to purge the air from the gas.

4. One of the ignition sensors is bent and/or too close to the burner. Look to ensure that the ignition pins and the heat sensor are completely vertical and they do a 90 degree to the back of the box. If they are not straight (i.e. a 45 degree angle) then you can straighten them with pliers. Please visit support.eccotemp.com or call 1-866-356-1992 for assistance with this matter.

5. The gas sensor wire might have come loose or is no longer connected. Please visit support.eccotemp.com or call
