(x) Connect oil supply pipe from tank to inlet of Oil Control
Valve - open all oil valves to allow oil into the control valve.
(xi) Depress trip lever
D
on the front of the oil control valve
P
(See Fig. 13).
(xii) Connect MAIN burner solenoid to 13A plug and
extension lead - switch on power to solenoid.
This will allow oil to flow to the burner without activating
the main controller.
(xiii) Wait about 10-15 minutes until the depth of oil within
the burner settles. Lower a dip stick through the hot plate
aperture, until it sets onto the burner base at its centre.
Remove the dip stick and measure the depth of oil which
must register 15-17mm depth.
To Correct Oil Depth
For small adjustments (1-2mm) - adjust oil control valve
height - for adjustments greater than this it may be
necessary to adjust the height of the burner base plate.
Should this be necessary then switch off the solenoid -
disconnect the pipe work and remove the boiler - release
the locking bolts on the base plate and turn the slotted
setting screws to the required position, re-check levelling
of base plate - replace burner and pipe work - switch on
solenoid and re-check oil depth.
WHEN CORRECT ENSURE THE VALVE IS LEVEL IN
ALL DIRECTIONS AND SECURE - INCLUDING THE
REAR SUPPORT SCREW. THIS MUST BE FITTED AND
SUPPORTING THE REAR OF THE VALVE.
OTHERWISE OIL RATES CAN CHANGE OVER A
PERIOD OF TIME.
(xiv) Switch
OFF
mains power supply to solenoid.
(xv) Disconnect the main inlet oil feed and the pilot feed at
the front of the burner. Collect the oil spill over into a
receptacle, then proceed to withdraw the boiler burner as
previously indicated.
(xvi) Replace the two interstage baffles, the end baffles
and the top VEE baffle. ENSURING THE CORRECT
LOCATION OF EACH BAFFLE.
(xvii) Re-insert the boiler burner into the combustion
chamber ensuring it is fully engaged, refit the tie bar and
secure with the tie bolts - DO NOT ALLOW THE BURNER
FRONT TO LIFT AS IT IS TIGHTENED UP.
(xvii) Re-connect the main and pilot oil feed pipes as
previously described.
(xix) Re-connect electrical cables to glo-coil terminals,
ensuring that the shakeproof washer is fitted under the
Glo-Plug Locking Nut - Insert Flame Sensor into burner
front plate and secure.
Adjust fire bricks so that there is a gap between them in
the centre.
(xx) Replace boiler front fire bricks, boiler cover plate and
hot plate assembly. Ensure boiler cover plate is down
correctly, that the front screw is secure and that the type
gasket is sealing.
(xxi) Check oil flow rate to main burner. - This should be
38 - 40 cc/min as measured by the DRIP FEED METHOD
FOR SETTING THE OIL RATES SEE SECTION ON
SETTING THE OIL CONTROL VALVE.
The cooker burner comes packed in its own carton.
1. Screw the carbon leg assembly into the base using an
oil resistant sealant. The carbon leg must be positioned in
line with the length of the burner base. The end which the
carbon leg faces when tightly screwed in place is the front
of the burner, where the burner support bar is located.
The support bar must be screwed into location using a
counter sunk screw before the final tightening of the
carbon leg.
2. Screw the levelling screws into the support bar.
3. Screw the adjustment leg into the rear of the burner.
Check that the height of the levelling screw in the
adjustment leg is 39mm from the top of the lock nut to the
base of the screw (Fig. 9).
4. Open outer burner door and lift remove R.H. cooker
inner burner door.
5. Place burner base into combustion chamber and check
base is level in all directions. (ENSURE THAT THE LEGS
OF THE BASE ARE ENGAGED IN THE ROUND
RECESSES PROVIDED).
There are three - two at the front and one at the rear.
It is essential this is done or any adjustment on height or
level of the burner WILL BE WRONG.
6. Connect oil supply pipe and turn cooker control knob to
No.6 this will allow oil into the burner base. Allow
approximately 15-20 minutes for the oil level to stabilise. -
then test oil depth this should settle to a depth of 6mm.
7. To correct oil depth, slacken the nuts securing the
threaded support legs and adjust the leg height to suit.
Re-check that the burner is level in all directions.
8. With the burner level and a constant oil depth of 6mm
tighten the locking nuts on the oil burner levelling screws.
IMPORTANT: THE COOKER BURNER BASE MUST BE
LEVEL IN ALL DIRECTIONS AND THE OIL DEPTH
STABLE AT 6MM.
Switch off oil, drain and disconnect.
Remove cooker burner base.
