TROUBLESHOOTING GUIDELINES
These guidelines should be utilized by a qualified service
agent.
LOCKOUTS
Soft Lockout
• Occurs when a system safety device trips to break the
sequence of operation. The control will try to start 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.
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.
