Troubleshooting
The “eHEnergizer” contains no user serviceable parts. A shock hazard is present with the device and
under no circumstances should the end-user attempt to disassemble the electronic unit.
Please contact Unifire support for assistance with unit installation, operation and fault finding
(
The following checks may be made by the end user to help identify root cause of problems.
Fault
Cause
Remedial Action
Red LED OFF
Power Supply Failure
If the red LED is not on then the
unit is not powered. Reconnect
power and try again.
No Spark
Ground failure
Check the ground connection
between the igniter tip and
“eHEnergizer” high side “G”
terminal. Must be < 0.2Ω
High Voltage Wire Connection
Failed
Check the integrity of the high
voltage wire connection to the
“IGN”
terminal
on
the
“eHEnergizer” and to the igniter
tip.
Igniter Tip Resistance
Verify that the igniter tip
resistance is at least 1MΩ but not
infinite (this would indicate a
material breakdown of the tip).
Pilot Does not Light
Lean/Rich Fuel – Air Mixture
Check that there is sufficient fuel
supply for ignition with a close to
stoichiometric mixture.
Check for debris/obstructions in
the air register/mixer of the pilot
burner
High / Low Fuel Pressure
Verify that the fuel supply
pressure
is
within
the
requirements of the pilot burner.
Fuel Quality
Typically pilots are operated with
natural gas. “Dirty” fuel that is, for
example, heavily laden with liquids
will prove difficult to ignite.
