UDB Fault History

To view the fault codes in the UDB history file:

1.Press the UP or DOWN buttons on the membrane switch for 2 seconds to access the fault history.

2.Press either button to scroll through the recorded faults in history.

3.The most recent fault recorded will be the first fault displayed (the last 16 faults are stored in the his- tory, on a rolling basis). There is no time or date stamp associated with these faults.

4.When the history of faults has been exhausted, pushing the UP or DOWN buttons again will roll the fault history over and it will start again.

5.To exit the fault history, wait for 10 seconds and the board will automatically exit the history mode.

To clear the fault history, press and hold both the UP and DOWN buttons for 5 seconds while the power is on.

NOTE: Once the history has been cleared, it cannot be recovered.

Diagnostic information is provided any time a fault is recorded. This information is intended to assist in locating the problem with the heater, but is not exhaus- tive.

If multiple fault conditions occur at the same time, only the fault that caused the heater to shut down will be recorded in the history.

MAINTENANCE

Suggested Minimum

Maintenance Schedule

Regular service by a qualified service agency and maintenance must be performed to ensure maximum operating efficiency.

Maintenance as outlined below may be performed by the owner.

Daily

1.Check that the area where the heater is installed is free from combustible materials, gasoline, and other flammable vapors and liquids.

2.Check for and remove any obstruction to the flow of combustion or ventilation air to heater.

Monthly

1.Check for piping leaks around pumps, mixing valves, relief valves, and other fittings. If found, repair at once. DO NOT use petroleum-based stop-leak compounds.

2.Visually inspect burner flame.

3.Visually inspect venting system for proper func- tion, deterioration or leakage.

4.Visually inspect for proper operation of the con- densate drain in the venting. If leaks are observed repair at once.

5.Check air vents for leakage.

Yearly (Beginning Of Each Heating Season)

Schedule annual service call by qualified service agency.

1.Visually check top of vent for soot. Call service person to clean. Some sediment at bottom of vent is normal.
