CAUTION

FOR HOUSEHOLD AND INDOOR USE ONLY.

SAVE THIS INSTRUCTION

ATTENTION

Increasing the water temperature setting 

may improve the cleaning performance of 
dishwashers. 

The user can adjust the temperature setting 

to meet their needs. Always read and 
understand the safety instructions contained in 
the manual before adjusting the temperature 
setting. 

If the water heater is to remain idle for an 

extended period of time, the power and water 
to the appliance should be turned off and the 
water heater drained to conserve energy and 
prevent a buildup of dangerous hydrogen gas. 
The water heater and piping should be 
drained if they might be subjected to freezing 
temperatures. After a long shutdown period, the 
water heater’s operation and controls should be 
checked by qualified service personnel. Make 
certain that water is flowing to water heater 
again before placing it in operation. 

Statement: ENVO does not assume any
responsibility for the losses caused by the
improper installation and behavior listed 
above or other improper operations.

It is extremely important to FLUSH the 

pipes to wash away sundries and residue in 
the pipes before connecting the water heater 
to it.

Risk of Fire - Hydrogen gas can be produced 

in a hot water system served by this water 
heater that has not been used for a long period 
of time(generally two weeks or more). 

HYDROGEN GAS IS EXTREMELY FLAMMABLE!!

 

To dissipate such gas and to reduce risk of 
injury, it is recommended that the hot water 
faucet be opened for several minutes at the 
kitchen sink before using any electrical 
appliance connected to the hot water system. 
If hydrogen is present, there will be an unusual 
sound such as air escaping through the pipe 
as the water begins to flow. Do not smoke or 
use an open flame near the faucet at the time 
it is open. 

Safety regulations require a factory setting no 

greater than 125°F (52°C) for all new water 
heaters. Therefore, if your old water heater was 
set to a hotter temperature than your new water 
heater with a factory setting of 120°F (49°C), the 
new water heater may seem to provide lower 
capacity than your old water heater. This can be 
corrected by increasing the temperature setting.
