7.5 B-1. INTRODUCTION
This troubleshooting guide is intended to aid
service/maintenance personnel in isolating the
cause of a fault in a Benchmark Series Boiler,
KC1000 Boiler or KC1000 Water Heater. The
troubleshooting procedures contained herein are
presented in tabular form in Table B-1 and B-2.
Table B-1 pertains to Benchmark and KC1000
Boilers and Table B-2 pertains to KC1000 Water
Heaters. Each table is comprised of three
columns labeled: Fault Indication, Probable
Cause and Corrective Action. The numbered
items in the Probable Cause and Corrective
Action columns correspond to each other. For
example, Probable Cause No. 1 corresponds to
Corrective Action No. 1, etc.
When a fault occurs in the Boiler or Water
Heater, proceed as follows to isolate and correct
the fault:
1. Observe the fault messages displayed in the
Control Box display.
2. Refer to the Fault Indication column in the
following troubleshooting tables and locate
the Fault that best describes the existing
conditions.
3. Proceed to the Probable Cause column and
start with the first item (1) listed for the Fault
Indication.
4. Perform the checks and procedures listed in
the Corrective Action column for the first
Probable Cause candidate.
5. Continue checking each additional Probable
Cause for the existing fault until the fault is
corrected.
6. If the fault cannot be corrected using the
information provided in the Troubleshooting
Tables, contact your local AERCO
Representative.
