EZ Supreme User Manual - page 19

LOW WATER PRESSURE IGNITION: 

In order to meet the needs of well users and those living at high altitudes, we specially 

designed a low water pressure ignition for this product. 

COMPUTER CONTROL: 

Computer controlled ignition and water flow sensor allow for maximum efficiency. 

MULTIPLE REDUNDANT SAFTEY PROTECTION SYSTEMS: 

Multiple safety protection devices. For example, in case of a sudden flame out or lack of 

water supply or electrical power, the systems provide an instantaneous automatic shut-off. 

TOUCH CONTROL PANEL SETTINGS: 

Design includes easy to operate LCD display of temperature settings, which can be 

adjusted using the simple “+” and “-“ buttons. - To save energy, to comply with US federal 

and state plumbing codes, and for liability reasons, the manufacturer of this water heater 

has preset the temperature control to 48C (120F) and this is the default setting. The 

temperature can be raised manually for single use purposes, but once the water is shut-off, 

the setting default returns to the 120F setting as dictated by state and federal law. 

Furthermore, to prevent tampering and danger of scalding, the pre-set temperature cannot 

be raised manually when the heater is in operation. The water flow must first be shut-off 

before the temperature can be raised via the control panel located on the front of this unit. 

(NOTE: Normal  bath  water  temperature  is  a b o u t   1 0 5 ° F   just for your reference.) 

NOTE: 

This product’s safety features are lab tested.  Please be careful and follow all State and 

Local regulations and codes when installing and using your tankless water heater. 

NOTE:  

WATER QUALITY 

No manufacturer builds a tankless heater that can hold sediment and mineral deposits 

inside. Tank type heaters often have deep sediment loads that build up over years and 

accumulate in the bottom of the tank. By design, there is no place in a tankless heater for 

this accumulation of sediments and minerals. Over time, your tankless heater will become 

less and less efficient unless you address the issue of water quality. This must be done at the 

time of installation. Even though you may have city water, there may still be unacceptable 

levels of sediment and minerals that can harm your tankless heater in a short period of 

time. Consideration of care for your water heater must include evaluation of your water 

quality. If the water quality exceeds the target levels provided in this table, to prevent 

build-up of sediment and minerals in the interior of your heater, you must pre-treat or 

condition the incoming water supply with a filter and/or softener system.
