FAN OPERATION
The 3-speed main convection fan will automatically start approximately 3 to 5 minutes after the heater has warmed up.
Note: The 3-speed main convection fan is automatically controlled and will operate on three preset speeds. Depending on your burner
setting and the surrounding ambient temperature, the L.E.D lights (Page 36, Figure 43) for the fan will light up. The bottom L.E.D light
(Figure 43F) is low speed setting, and middle L.E.D lights (Figure 43G) is the medium speed setting, the bottom, middle and top L.E.D
lights (Figure 43H) is the high-speed setting (both burners on).
Note: The fan will operate totally independent of burner setting - it is controlled by temperature only.
a. Front burner only - low fan speed
b. Rear burner only - medium fan speed
c. Both front and rear burners - high fan speed
On changing the burner setting from high to medium, or from high to low, there will be a delay on the operating speed of the fan until
the firebox has cooled down sufficiently for the fan to change speed.
Note: It can take up to approximately 20-30 minutes before the fan speed will change and settle on the next setting. The firebox tempera-
ture and the outside ambient temperature will regulate how quickly the fan responds to speed changes.
HEATER SHUT DOWN INSTRUCTIONS
Turn medium burner switch (Figure 42) and low burner switch (Figure 41) to the “OFF” position.
Note: Do not cut main electrical supply to the heater after the heater has been switched off to stop main fan operating. Main fan will
stop operating automatically after the heater has cooled down sufficiently.
