TROUBLESHOOTING

10. TROUBLESHOOTING
A. BLOCKING ERRORS
1. When a Blocking Error occurs the controller will
display a message and an "E" error code on the
display module.
2. These error messages and several suggested corrective
actions are included in Table 10.1.
3. Certain Blocking Errors will, if uncorrected, become
Locking Errors as described is Paragraph B.
B. LOCKING ERRORS
1. When a Locking Error occurs the controller will
display a message and an "A" error code on the
display module.
2. These error messages and several suggested corrective
actions are included in Table 10.2.
3. Press the reset key to clear the Locking Error and
resume operation. Be sure to observe the operation of
the unit to prevent a recurrence of the fault.
4. The Infinite Energy control will retry for ignition after
one hour of being in a lockout condition. This will
prevent lockout errors from resulting in "No Heat"
calls if there is an intermittent problem.
5. The Infinite Energy control logs the flame signal four
times during the last 2 seconds of the ignition period.
This is to aid in troubleshooting ignition errors. A
flame signal below 2 micro-amps at the end of this
period will result in a lockout. If the flame signal is
low, remove the flame sensor and igniter for
inspection. Also, be sure that the lead to the flame
sensor is not grounded.

WARNING
Do not use this appliance if any part has been under
water. Improper or dangerous operation may result.
Contact a qualified service technician immediately to
inspect the boiler and to repair or replace any part of
the boiler which has been under water.
CAUTION
If overheating occurs or the gas supply fails to shut
off, do not turn off electrical power to the circulating
pump. This may aggravate the problem and increase
the likelihood of boiler damage. Instead, shut off the
gas supply to the boiler at the gas service valve.
CAUTION
Label all wires prior to disconnection when servicing
controls. Wiring errors may cause improper and
dangerous operation. Verify proper operation after
servicing.
CAUTION
The convenience outlet is powered even when the
service switch is off.
