Caution: When switching from the front burner to the rear burner, be sure to activate the rear burner first, then turn off the front burner.
When switching from rear burner to the front burner, be sure to activate the front burner first. Simple rule - always activate the
desired burner first, then switch the other burner off. If it is switched the wrong way, the burner(s) will go out and the heater
may need to be reset. Refer to page 48 - Resetting the Heater.

(Figure 66C and 66D) will start flashing for 35 seconds
prior to ignition. Once both burners have ignited, the burner
L.E.D's will remain on. If you can't 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 (Figure 66F)
will light and the convection fan will blow warm air from
the heater. As the heater becomes warmer, the medium L.E.D
(Figure 66G) will come on. When the heater has reached its
highest operating temperature, all three L.E.D's will light up
and the convection fan will now be running at its high speed.
Refer to page 39 - Fan Operation. When the heater has been
running for some time, the water pump L.E.D (Figure 66B) may
come on to signal that the pump has been activated. Refer to
page 40 - Automatic Humidifier Operation.
