ex) low combustion damper open : 2/10 open.
medium combustion damper open : 4/10 open.
high combustion damper open : 6/10 open.
ⓐ see each CAM of the damper open scale. accord with marked CAM scale
according to the setting position.
ⓑ when adjustment is over, and adjust damper plate to the low combustion
damper opening using the knob on the opposite side of the motor.
㉢ turn on the power. and adjust damper again while reviewing the operating
conditions of combustion. in this case make it sure to confirm that each switch
turns off sequentially from the low combustion damper CAM.
㉣ overrun protection s/w
when low or high combustion damper CAM is mistakenly adjusted.(for example,
low combustion damper CAM is set below zero in the damper scale or high
combustion damper CAM is set adove 10 in the damper scale) or when the low
or high combustion damper s/w is out of order. press the overrun protection s/w
to stop damper operation.
ⓐ when pressing the low overrun protection s/w.
readjust the low combustion damper CAM when the s/w is out of order,
replace the s/w. when it is completely closed, use the manual adjuster knob
to set in ti the low combustion opening position.
ⓑ when pressing the high overrun protection s/w.
readjust the high combustion damper CAM when the s/w is out of order,
replace the s/w.
3) HOW TO DISASSEMBLE, CLEAN AND REPLACE NOZZLE.
① the nozzle sprays fuel through fine hole(㉠)
② air flow rate and pump pressure are adjustable per the capacity of nozzle which is
specified in terms of spray rate, angle and patten.
③ capacity
G/H (gallon/hour): the capacity id specified as to consume 3.785 liters of
kerosene per hour under the pressure of 7㎏/㎠.
④ 80°: fuel is sprayed from nozzle hole in 80 degree angle.
⑤ when burning conditions are not satisfactory bue to inappropriate splay of fuel,
remove, disassemble and clean nozzle using kerosene.
a) how to replace nozzle.
ⓐ disconnect power.
ⓑ pull out one side of hinge pin to open the burner flame.
ⓒ hold nozzle adapter with spanner, and loosen nozzle counter clockwise.
ⓓ after changing nozzle, check and adjust the place of ignition by with referring to
assembling dimension of combustion head.
ⓔ replace nozzle in the reverse order.
