Frequently Asked Question ("FAQ")

Q1: What is the purpose of the On/Off switch at the bottom of the unit?
A1: It allows you to have water flow through the unit without the water being heated. Turning off the gas regulator will achieve the same effect.

Q2: What is the purpose of the flat, angled piece of metal that is attached to the top and back of the heater?
A2: This part was a vent hood, and is no longer shipped with the L5. When it was included, its only purpose was to reflect heat forward.

Q3: How do I add the high temperature sensor?
A3: Inside the unit, at the top right-hand corner is the original sensor. Remove it and replace with the new sensor. For further assistance, please contact Eccotemp at

Q4: Is it possible to use the the small Coleman-type propane canisters, or the 1 lb camp stove size bottles as a fuel source?
A4: Yes. Simply use an adapter for the regulator to convert the standard connection to the smaller thread size. These adapters are not included, but available elsewhere at most hardware or outdoor supply stores.

Q5: How long will a 20 lb tank last as the fuel source for this heater?
A5: One of our customers reported that a 20 lb tank lasted one month for two or three showers per day. Or, that's one shower per day for two to three months.
