Flame failure or
power flue trip
Power Flue Unit
NZ Only
(PFU)
The fire has tried to light three times and failed.
- Check gas supply and other gas appliances to see if
they are affected. If you have two separate LPG
cylinders, switch over to the full bottle or contact your
gas supplier. You may need to retry igniting the fire a
few times after re-establishing gas supply.
- Check that there has not been a significant reduction
in air pressure inside the house (such as an extractor
fan in a nearby kitchen) which can pull flue gas back
down through the firebox "snuffing" the flames.
Additionally if the living space is built such that no
adventitious ventilation is available (small gaps around
doors widows etc..) the flow of exhaust gasses may stall
and snuff the flames (this may produce an E3 error
also). This can be checked by opening a nearby
window or door to the outside when the fire is faulting
to see if there is an improvement. In this case it may be
beneficial to add some ventilation to the living space
to balance the air being drawn up the flue.
- Alternatively this may indicate a problem with a PFU
installation. If for any reason the exhaust flow is stalled
or backs up, the pressure switch in the PFU will trip and
shut off the burners. If this flow disruption continues for
longer than the normal ignition period it may cause an
E2 Error. Brief wind gusts may trip the pressure switch
and shut off the burners momentarily but the fire will
attempt to relight immediately after the pressure switch
resets with normal exhaust gas flow.
