Please Note:

1、When install the water heater please do not over tighten the connectors and pipes to prevent it from bursting and leaking.

2、The exhaust and top will get hot, please check around area for flammables, especially gasoline or other vapors which may ignite. Please make sure there are no foreign objects around the portable tankless water heater or have fallen into the top.

3、A gas leak detection is needed before use and please do not use flame for leak detection. Soapy solution, gas detectors, etc. are recommended to detect leaks.

4、Please use only liquid propane as fuel and use it in a well-ventilated place.

5、Please make sure there is enough water pressure. If the water pressure is below 2.5 PSI, the water heater cannot be ignited.

6、If the outside temperature is around or below freezing(0℃/32℉), please ensure to drain out the water after each use to avoid internal damage to the heat exchanger.

7、This water heater is not suitable for high altitude areas over 3300 feet and strong wind conditions.

This compact , yet powerful unit – with gas inputs up to 140,000 BTU per hour – can meet all the hot-water needs of a small to medium American home or apartment. Designed to virtually do anything a 40-gallon tank-type water heater can do and much more The Wall mounted Excel Pro is design to work with hydronic baseboard or radiant floor heating applications, as well as provide domestic hot water to plumbing fixtures and appliances. LCD Display Control: Just set the desired water temperature The Excel Pro has an energy factor of 0.84-0.85. Excel Pro: Modulating Technology Tankless water heaters can be further divided into two categories according to their heating capability: “full on/full off” versus “modulating”. Full on/full off units do not have a variable power output level; the unit is either fully on or completely off. This can cause an annoying and possibly hazardous variation of hot water temperature, as the flow of water through the heater varies. Modulated tankless water heaters change their heat output in response to the flow rate of water running through the unit. The Excel Pro comes with a display panel where you can set the output temperature and regardless of water flow the unit modulates the fire power.
