STARTING THE MAIN HOPPER DIESEL BURNER AND
SETTING THE TEMPERATURE CONTROLLER
(CONTINUED)
c)
NOTE: While performing this step, never adjust the inner air band on the diesel burner.
Whenever checking the burner nozzle, inspect the electrode tip settings (see figure 3 on
page 77 of this manual) and replace electrodes if the tips are rounded.
The burner nozzle
may be fully or partially plugged preventing the diesel burner from igniting. The nozzle should be
changed semi-annually or after 500 hours of use -- whichever comes first. To check for a clogged
nozzle, adjust the
outer air shutter (see figure 9 on page 83)
on the diesel burner to the number
1 (the lowest setting), turn the HOPPER toggle switch off/down and on/up, then
slowly
move the
outer air shutter from a position of 1 to 4 as the blower motor is running for 30 seconds to see if the
air shutter adjustment helps the burner ignite. If the burner ignites with the outer air shutter is at a
point less than a setting of "4", the nozzle needs to be replaced. Turn off/down the HOPPER
toggle switch, return the outer air shutter to the factory setting of 4 and install new burner nozzle
being careful not to touch the mesh screen. Oils from hands may plug the nozzle. After changing
the nozzle, turn the HOPPER toggle switch off/down and on/up and wait 30 seconds for burner to
light. NOTE: Cleaning the nozzle may be a temporary fix until a new nozzle can be installed. The
burner will not function properly with the outer air shutter set too low on a permanent basis. If the
burner still does not ignite, proceed to the next step.
d) Turn hopper switch off/down. Clean the blower wheel, air inlet, air guide and retention head of
any dirt, asphalt or other material. Inspect igniter spring contacts and clean or replace if corroded.
Turn hopper switch on/up and attempt to ignite diesel burner.
If burner still does not light, contact Falcon at (989) 495-9332.
