COMMISSIONING AND TESTING

CHECKING BOILER FLOW RATES
1. After checking the burner is level and that the oil is
the correct depth in the burner disconnect the oil
feed pipe to the burner and attach adaptor for
measuring by the DRIP FEED METHOD.
2. Turn the cooker oil control valve knob C on the oil
control valve to No.6 setting to establish oil flow,
allowing 2 min. Always set low fire rate first.
3. Turn the cooker oil control valve knob C on the oil
control valve to No. 1 setting - check low fire setting
- this should be between 4.0 to 4.25 cc/min.
NOTE: ALLOW 7 MINUTES FOR THE FLOW TO
STABILISE BEFORE TAKING THE RATE. IF THE
RATE IS INCORRECT THEN ALLOW 2 MINUTES
BETWEEN RE-SETTING AND THE NEXT RATE.
4. If the rate is incorrect then turn the low fire setting
screw as shown on the cover plate to increase or
decrease the flow. See Fig.10.
5. Now turn the cooker oil control valve C on the oil
control valve to No.6 (High Fire) and check rate -
AGAIN ALLOW TIME AS ABOVE FOR THE OIL
RATE TO SETTLE. If incorrect adjust high fire rate
by turning the high fire setting screw as shown on the
cover plate. See Fig.10. This should be between
12.75 to 13.0 cc/min for the boiler model or 8.5 to
9.0 cc/min for the non boiler model. ALLOW TIME
FOR RATE TO SETTLE.
6. Smoke Test: On Burner
Identify a sampling hole in the front of the flue hood
assembly. See Fig. 5.
Sample the flue products through the hole for a
Smoke Test utilising a Baccarach Smoke Pump
where all reading should indicate a Smoke Number
0-1 under the following checks:
(i) At low fire rate.
(ii)At high fire rate.
WARNING: NEVER ATTEMPT TO RELIGHT A HOT
BURNER - DO NOT TURN ON UNTIL THE BURNER
IS COOL.
LIGHTING THE OIL BURNER - See Fig. 9
1. Remove the oil control valve cover, then depress the
trip lever D on the front of the oil control valve and
turn the cooker oil control valve knob C to No.6
setting.
Allow 15 minutes for oil to enter and settle in cooker
burner base.
2. Open outer burner door adjacent to the bottom
warming oven door, remove/lift out inner burner
door.
3. Lift hinged lighting cover on the front of the burner
shell and expose the lighting port.
4. Insert a taper through the lighting port and light the
front wick, then close the lighting cover.
5. Replace inner burner door and close outer burner
door.
NOTE: ENSURE INNER COOKER BURNER DOOR IS
CORRECTLY LOCATED AND SEALED.
6. Return oil control valve knob C to its No.1 setting for
about 20 minutes, until the burner is hot, then re-set
to No.6 for cooking.
7. The cooker burner will gradually increase its oil rate,
and raise the temperature of the oven, talking about
2 1 / hours from cold to attain an oven temperature
2
of 200ºC (400ºF), leaving the cooker oil control
valve knob C at its No.6 setting.
Re-set the cooker oil control valve knob C to an
intermediate setting and the oven temperature will
maintain the desired temperature.
8. Set the cooker oil control valve knob C to No.1 which
is the minimum setting when cooking is not required
and idling rate is needed.
9. Ensure both hotplate insulating covers are closed
down to conserve heat in hotplate.
