Resetting The Heater Control; Lockouts; Soft Lockout; Hard Lockout - Smith BTF-80 SERIES 210 Installation And Operating Manual

RESETTING THE HEATER CONTROL

•
Soft lockouts as diagnosed by the system error codes
require the gas control to be reset.
•
To reset the control, slide the "ON/OFF" switch to the
"OFF" position. Wait for 10 seconds and move the
switch back to the "ON" position.
•
If the problem that caused the control to lock out has
not been corrected, the control will remain or again go
back into lockout.

LOCKOUTS

Soft Lockout

•
occurs when a system safety device trips to break the
sequence of operation. The control will retry the system
in a timed basis but will not reinstate operation until the
failure is corrected.

Hard Lockout

•
occurs when the main controller fails and must be
replaced.
The gas control valve\thermostat includes a temperature
limiting ECO (Energy Cut Off) system that will shut off the
water heater if the water temperature is too high.
Should the water temperature get too high, the diagnostic
status light will indicate a code (4 fl ashes), indicating an
over-temperature condition and the main burner will be
shut off. If a high temperature condition occurs, turn the
main gas supply OFF and have the water heater repaired
by a qualifi ed service technician. Contact your local dealer
for service information.
Note: Should an over-temperature condition occur, restart
the water heater and verify the LED fl ash sequence. If the
4 fl ash sequence is observed, slide the "ON/OFF" switch to
the "OFF" position. Turn Main Gas Supply "OFF". Replace
the gas control valve\thermostat.
