Slant/Fin KC-45, KC-90 manual What The Indicator Lights Tell You, In Case Your Boiler Shuts Down

® 3

ANNUAL TECHNICIAN INSPECTIONS

Before each heating season, call your qualified service technician to perform the following inspections (and repair any problems encountered).

Check Vent System: For corrosion, obstructions, leaks or sagging. Will require disassembling and resealing of vent tubing.

Check Water System: For water piping leaks, properly filled boiler and proper system air elimination.

Check Gas Piping: For gas valve and piping leaks.

Check Boiler Controls: For correct settings and functioning. To include safety controls and calibration.

Check Air Filter: Replace (recommended) or clean.

System Heat Exchanger and Burner: For sooting, corrosion or improper operation.

Blower and Circulator: Sealed components which do not require lubrication.

WHAT THE INDICATOR

LIGHTS TELL YOU

The PRODIGY 21 control light panel has a complete set of LED indicator lights which provide important information at a glance about boiler operation:

Power Indicator (RED): Steady ON means there is electrical power to the boiler. Light will come on when power is provided to boiler.

Diagnostic Indicator (RED): Steady ON or intermittent flashing indicates a system operation problem.

Full Input Indicator (AMBER): Steady ON means the boiler is running in high-fire mode. Light will come on when boiler starts up; will go off when the boiler enters the low-fire mode or shuts off.

Reduced Input Indicator (GREEN): Steady ON means boiler is running in low-fire mode. Light will come on when the boiler automatically switches to the fuel- saving low-fire mode; will go off when boiler returns to high-fire mode or shuts off.

IN CASE YOUR

BOILER SHUTS DOWN

Before calling a qualified service technician, check the following first:

•Room thermostat is calling for heat?

•Fuse or circuit breaker is OK?

•Boiler service switch is ON?

•Gas supply is available to gas meter?

•Manual main gas shutoff is open?

•Boiler gas control arm is in ON position?

Then, observe indicator lights: You can help provide useful information to the service technician so the technician can arrive with appropriate replacement parts.

Carefully note the red diagnostic indicator light. When a system failure occurs, and there’s power to the boiler, the indicator light will show a series of quick flashes. There will be a short interval between the series when the indicator stops flashing.

	BOILER FAILURE CODES
Continuous Flashing--		Electronic Control Failure
1	Flash -------------------	High Limit Open 1 Hour
2	Flashes ----------------	No Ignition
3	Flashes ----------------	Pressure Switch Open
4	Flashes ----------------	Hot Surface Ignitor Failure
5	Flashes ----------------	Blower RPM Too Low
6	Flashes ----------------	Low Water Cutoff Open
7	Flashes ----------------	Improper Flame Signal
Steady ON --------------		Loss Of Flame Signal

Count the number of flashes that occur after the short no-flashing interval. Using the chart above, determine correct failure code for number of flashes you counted.

Call a qualified service technician and report your boiler model plus the number of flashes you counted and the code for the flashes.

Note: The boiler will attempt restart each hour and after a power interruption. If boiler restarts, diagnostic light will turn OFF. If boiler does not restart, diagnostic light will return to either steady-on or the series of flashes.
