Having trouble with out eight year old Trianco Utility. Initially we
were getting many lockouts (shuts down with warning light, which needs
resetting) and bad ignition. After the service gent replaced the oil
pump (twice, the first one failed) and sensor and disconnected the
Tiger Loop, these went away. He also replaced the coil/transformer but
concluded this was not at fault and re-fitted old unit. Had been
regularly serviced previously and we do have confidence in the current
Lockouts/bad ignition have gone away. Problem now is that the flame
extinguishes briefly after 5/10mins running, leaving the oil pump still
running, and then reignites shortly after. This cycle occurs
The boiler man now thinks the balanced flue is leaking fumes into the
air inlet, which extinguishes the flames. This sounds a convincing
argument, except I hadn't noticed this problem before the latest round
of changes. When he runs it with the air pipe disconnected from the
flue (and the flue inlet blocked), the problem seems to go away.
Problem is, so much has changed and before I add significantly to an
already-high bill, I want to be sure. Not sure extent to which the
problem is caused by:
- the flue (and I assume I hadn't noticed it previously), and/or
- the new pump, more powerful than the OEM (a Danfoss 11L3, now a
- the removal of the Tiger Loop.
Anyone had this experience before?
Happy New Year
