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. Pure Copper Heat Exchanger * As used by other top of the line tankless gas water heater manufacturers like Rinnai, Takagi, Rheem and Noritz. Features & Benefits Super compact 14.5″ x 23″ x 5.5″ size 84%+ thermal efficiency 140,000 BTU maximum input 6.6 gallons/ minute capacity at 35F degree rise Minimum activation flow rate of 0.5 gpm Electronic ignition. Has a Power vented fan that Vents directly vertically or horizontally with 3” stainless steel flue 3′ long flue and elbow included. Can be used in recirculation and space heating application . Delivers 6.6 gpm of hot water with a 35°F Instant Temperature Rise (Equivalent to 5.5gpm with a 45F temp Rise). European Model Digital Display is in Celsius.

Description:
1. High efficient energy saving : the heater exchanger and main burner adopt mostly advanced energy-saving and combustion technology to decrease gas consumption and burning noise.
2. Low water-pressured startup : the water control linkage valve makes the heater start up under low water pressure and shortage areas and those living in high stairs.　
3. Manifold auto protection : for the sake of your safety　
4. Ion flame inspection : to automatically shut down gas power under unexpected flameout.　
5. Over water pressure protection function : to automatically decrease pressure under excessive high water pressure.
6. Controller design : both cold water and warm water can be properly controlled
7. Magnificent thin-shaped appearance : it is designed by modern fashionable line shape.
Attention:
We have adapters which can convert G thread connector to NPT connector (not include in the list) ,if you need ,please search ASIN: B01N03LFUF on our shop.
