Status Icons - Smith XWH 150 Instruction Manual

STATUS ICONS

The Status Icons are displayed on the Desktop screen and convey operational and diagnostic information. The icons are described in
the table below. Ensure the water heater is properly grounded. Flame sensing requires an adequate earth ground. If the water heater
is not properly grounded it will cause ignition failure.
