Note:
The flow rate should not exceed 20 cc/min as
this will overheat the cooker and the control
equipment for the cooker.
When the required rates are obtained, the oil
line should be reconnected ensuring that
there are no leaks and that the level of the
control valve has not been affected.
VITREOUS ENAMEL CLEANING
General cleaning must be carried out when the
stove is cool.
If this stove is finished in a high gloss vitreous enam-
el, to keep the enamel in the best condition observe
the following tips:
1.
Wipe over daily with a soapy damp cloth,
followed by a polish with a clean dry duster.
2.
For stubborn deposits a soap impregnated
pad can be carefully used on the vitreous
enamel.
3.
DO NOT USE ABRASIVE PADS OR OVEN
CLEANSERS CONTAINING CITRIC ACID
ON ENAMELLED SURFACES. ENSURE
THAT THE CLEANSER MANUFACTUR
ERS INSTRUCTIONS ARE ADHERED TO.

1.
Disconnect the oil feed at the exit from the
control valve. (See Fig.34)
2.
Place the collection vessel beneath the con
trol valve to catch the oil. Turn the control
valve to 6 and start the stopwatch when the
first drop of oil falls into the vessel.
3.
Measure the oil flow for 5 minutes. (consult
table below for current rate).
4.
Turn the control valve to 1 and repeat the
above procedure.
5.
If either of the above rates is not correct, the
control valve can be adjusted. The high rate
screw is located above the control knob with
the low rate located below the control knob.
(See Fig.35) The screws are very sensitive
and the measurement procedure should be
carried out after each adjustment. The rates
are increased by turning the screws anti
clock-wise and decreased by turning the
screws clock-wise.

CONTROL VALVE RATING
The control valve must be rated by the
Commissioning Agent on site to give the required
fuel input for the cooker.
When the flame pattern is unsatisfactory, the air sup-
ply to the burner and flue passages should be thor-
oughly investigated before investigating the oil feed
rate to the burner.
Check the oil feed rate as follows:
Note:
Great care should be taken to ensure the
accuracy of the flow rate, as it greatly affects
the cooker performance.
Apparatus Required: Collection Vessel
Stopwatch
Graduated Cylinder (capable
of measuring 150ml and grad-
uated to the nearest ml)
Small flat screwdriver.
