Fault Diagnosis/Troubleshooting
Every CVO fire is tested in the factory and give a 40 point check to ensure it
operates correctly. It is highly unlikely it would not operate when installed as
designed. The biggest cause of installation problems with this fire are caused
by incorrect GAS PRESSURE. This is normally due to ignoring the instructions
in the section “READ THIS FIRST” where is clearly states to check the gas pipe
work before installing the fire. This is a 12kw appliance and needs a very
strong gas supply that is maintained at within 1mBar of the appliance setting.
NATURAL GAS = 19mBar to 21mBar.
LPG = 36mBar to 38mBar.
If the commissioning procedure is not followed and the fire is left to
run with the wrong gas pressure the fire will:
1. Fail to light.
2. Light for a few seconds.
3. Shut down unexpectedly.
4. Have a low flame.
5. Have a yellow flame.
6. Cause sooting in the enclosure.
Other areas to check during installation are:
1. Has the pilot been knocked and the gap too large?
2. Are the batteries fitted properly?
3. Is the magic eye positioned correctly?
4. Is the flue operating correctly without reverse drafts or air leaks?
Common Faults
• Spark Gap incorrect [see manual]
• No Power or fuse blown [see manual]
• Gas Pressure too high or too low causing sudden appliance
shutdown or incorrect flame pattern. Low gas pressure causing a
long or repeated ignition period before the fire will light.
• Gas leak in the inlet pipe work causing a long or repeated
ignition period before the fire will light. This is due to the gas in
the pipe work being replaced by air.
• No Room Ventilation being provided.
• Incorrect Flue System causing sudden shutdown of the
appliance.
• Not following the lighting procedure [read lighting section]
• Not using the hand set properly [read lighting section]
• Incorrect wiring of the manual wall switch [see manual]
