2 FCC rules
FCC: This device complies with Part 15 of the FCC rules. Operation is
subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.

The chart below shows the relationship between water temperature and
time until there is a risk of scalding. It can be used as the basis for
determining the safest water temperature for your application.
3Appliance details
3.1 Features
Parts
• Key Pad interface control.
• High power pre-mix compact burner with low NOx emissions.
• Modulating Gas Valve with constant gas:air ratio control.
• Modulating water valve for improved comfort and temperature
control.
High quality materials for long working life
• Copper heat exchanger.
• High efficiency Ceramat Burner.
• Compact space saver: mounts on a wall with a supplied bracket.
Features
• Easily removable one-piece cover.
• On/Off and Temperature control switches.
• Reset button.
• Program button (Selectable temperature default).
• Failure codes for easy diagnostics and repair.
• Real-time diagnostics for troubleshooting/informational purposes.
• Built in freeze prevention.
Note: The freeze prevention kit is designed to provide protection for the
water heater down to approximately 5°F for short term conditions only.
It will not protect the appliance in areas where the temperature is
routinely expected to be below freezing.
- The freeze prevention kit will not protect plumbing outside the
appliance from freezing. Precautions should be taken.
WARNING: Personal Injury from toxic chemicals.
▶ A water heater which will be used to supply potable
water shall not be connected to any heating system
or component(s) previously used with a nonpotable
water heating appliance.
