TROUBLESHOOTING
Scenario 1: The pulse switch (at the wall) is depressed but no spark at the electrode
•
Check that the earth wire is connected
•
Check the main power is turned on
•
Ensure correct wiring according to wiring diagram (wiring to switches/ electrodes) on page 10
of this document
•
Ensure the gap between the electrode and the earth is approx. 6mm
•
Check that the ceramic insulator on the electrode is not cracked (if so contact Warmington Auckland office for replacement)
•
Check the spark electrode is not coated by soot or dust
•
Check the spark electrode is not burnt out/ melted (contact Warmington Auckland office for replacement)
Scenario 2: The unit is sparking but failing to light
•
Verify that the gas supply to the unit is turned on
•
Check that the solenoid valve is operating correctly
•
Ensure that the electrical wiring to solenoid is correct
•
Ensure correct jet for gas supply (LPG/ NG)
•
Ensure all wiring and electronics are in a moisture free environment
Scenario 3: The unit lights but goes out after a short time
•
Check the flame rod is in the flame path
•
Check the setting of the timer in the control box. Normal timer setting is 12 minutes.
•
Ensure burner head, control box and wiring are dry and not installed where moisture could build up or affect the electronics.
Scenario 4: The flame burns well away from the burner head
•
Check the correct jet for the gas supply (LPG/NG)
•
Check the gas pressure
Scenario 5: The flame burns sooty
•
Check that the aeration setting to the unit is correct. There is a cast fitting that ensures aeration of the gas before burning. On the
flares, this fitting is on the outside of the unit (under the perf). On the rail burners and tee bars, the fitting is inside the main
housing. For natural gas, this fitting should have 4 holes exposed for aeration. For LPG, 10 holes should be exposed. If a natural
gas fitting has been supplied for running LPG, the flame will burn sooty. Contact the Warmington Auckland office if the fitting
needs to be replaced.
Note:
If unit is fitted with an LED, the LED will light up on a flame failure.
The time from starting to ignition is approx. 30 seconds.
A flame will conduct direct current (DC) through itself. Alternating current (AC) is supplied to the electrode, usually called a flame rod,
which is in contact with the flame. The flame conducts only the DC to the earthed burner, thus partially rectifying the current. This partial
rectification of the AC to DC creates a specific current wavelength, which is monitored by the control unit.
Only flame rectification produces the correct current wavelength. If the flame fails, or if there is any electrical fault or failure, the current
wavelength changes and the control unit operates the gas shut
-
off valve or system.
