Heater operating LED sequence (Front Display Panel). Before commencing ensure that the power L.E.D
(Item 3) is on and burner switches are off. Switch on the heater by engaging the low and medium burner
switch, this will activate the pressure switch and the flue fan L.E.D (Item 4) will be on. Also the two burner
L.E.D’s (Items 5 & 6) will commence flashing for 35 seconds prior to ignition. Once both burners have
ignited the burner L.E.D’s will remain on. If you cant see flame on the rear burner, but the burner L.E.D is on
then there will be flame there, which will become more visible as the heater warms up. Once the heater warms
up the low speed L.E.D (Item 7) will light and the convection fan will blow warm air from the heater, as the
heater becomes warmer the medium L.E.D (Item 8) will come on and when the heater has reached its highest
operating temperature all three L.E.D’s (Items 7, 8 & 9) will light up and the convection fan will now be
running at its high speed. Refer Page 32 - Fan Operation. When the heater has been running for some time, the
water pump L.E.D (Item 10) may come on to signal that the pump has been activated.
