If your Eccotemp Portahot will not ignite, please review the following troubleshooting guide:
1. Check your propane tank to determine if you are out of gas.
2. Check your batteries to see if they are properly installed. Are your batteries new? If not, try another set. When checking your batteries and encounter corrosion, gently clean the connections with a wire brush and install a fresh set. Be careful when doing this, as battery acid is extremely harmful and poisonous.
3. Disconnect the incoming water line. There is a screen immediately inside of the incoming water pipe that may have clogged over time and is reducing the water flow and water pressure. After following these steps, test to see if the water heater is working. If you are running your L5 / L7 with something other than the showerhead connected to the outgoing water line, such as plumbing, disconnect this and try to operate the water heater to determine if your plumbing is the issue. You need to have a minimum of 20 pounds per square inch of water pressure to activate and sustain operation of the L5 / L7 water heater. If you cannot achieve and maintain adequate water pressure, your water heater will function erratically or not at all. If you have low pressure that is near adequate, please follow the link below to access instructions on increasing your L5's / L7's sensitivity to water pressure:
If those steps did not help, turn off your gas supply. Take the cover off by removing the 2 screws at top and 2 on the bottom and the knobs pull off. Disconnect and reconnect all wire connections to ensure that everything is properly seated. To test your electrical system, please click on the link below:
