6.4 Troubleshooting Guidelines

Attached are a series of troubleshooting checklists to aid the user in resolving each specific fault

code.

Note: Attempt to start the heater a total of three (3) times prior to the

initiation of Heater Maintenance.

Note: More than one action may be required to resolve a Heater Fault Code.

Note:

If the heater alternately displays a Fault Code with one of the current

Run settings (07 or 14), the heater is attempting to compensate for an

abnormal operating condition.

If the condition remains, the heater will

continue to operate as long as possible.

If safe heater operation is no

longer possible, the heater will shut down and display the appropriate Fault

Code.
