INSTALLATION INSTRUCTIONS

COMMISSIONING

3. CHECKING OIL FLOW RATES

NOTE: THE OIL CONTROL VALVE IS FACTORY SET.

THIS ONLY NEEDS TO BE CHECKED OR ADJUSTED IF IT

IS SUSPECTED THAT THE BURNER IS USING TOO

MUCH OIL

 •TurntheOilControlValveOFFbyturningtheControl

Knob fully clockwise

 • Disconnecttheoilfeedpipeaftertheoilcontrolvalveat

the compression elbow and place a suitable calibrated

measuring vessel under the outlet port of the oil control

valve

 • Lifttheoilcontrolknobslightlyandturntothemaximum

setting 6 for approximately two minutes to establish oil flow

 • Turntheoilcontrolknobtothesetting1tocheckthe

LOW FIRE SETTING, this should be 4.0cc/min.

ALLOW AT LEAST 10 MINUTES FOR OIL FLOW RATE TO

STABILISE BEFORE CHECKING. If adjustment is necessary,

this can be altered by turning the Low Fire adjustment

screw 11 clockwise to decrease and anti-clockwise to

increase the flow rate.

Care must be taken when adjusting flow rates. The adjusting

screw should only be turned a quarter of a turn at a time.

Allow the control to stabilise between adjustments then

re-measure the rate.

 • Turntheoilcontrolknobtomaximumtocheckthe

HIGH FIRE SETTING, this should be 8.0 cc/min.

ALLOW AT LEAST 10 MINUTES FOR OIL RATE TO

STABILISE BEFORE CHECKING. If adjustment is necessary,

this can be altered by turning the High Fire adjustment

screw 8 clockwise to decrease and anti-clockwise to

increase the flow rate.

 • Allowatwominuteperiodinbetweenscrewadjustments

for the oil rate to stabilise

 • Reconnectoilfeedpipework

NOTE: AVOID KINKING IN THE OIL FEED PIPE; IT

CAUSES AIR LOCKS. ALWAYS RUN THE PIPE TO A LOW

POINT, THEN PROVIDE A GRADUAL UPWARD SLOPE

TO THE BURNER.

4. BURNER LEVELLING

4.1 Open the Burner Door and remove the Burner Cover

4.2 Remove the Burner Lid, Burner Shells, Vapour Chamber

Lids and Wicks

4.3 Place a Cross Test Level on the Burner Base, adjust the

levelling studs until the base is level in all directions. Tighten

the lock nuts on the levelling studs and recheck for level.

4.4 Turn the Oil Control Knob to maximum and allow oil to

enter the Burner Base. Allow 15 minutes for the oil to

stablise. Check the oil depth, this should be between 5mm

and 6mm. Correct if necessary by adjusting the height of

the Oil Control Valve as in 4.3 above.

4.5 Replace the wicks ensuring that the cut outs are arranged in

line with radial ports facing downwards.

4.6 Replace the Vapour Chamber Lid. Make sure that both

surfaces are clean and free from damage. Place the Lid in

position and rotate applying hand pressure; remove the Lid

and check that a complete witness mark is evident, then

replace the Lid.

NOTE: UNDER NO CIRCUMSTANCES MUST ANY

SEALANT (FIRE CEMENT OR SILICON) BE USED. THE

WEIGHT OF THE VAPOUR CHAMBER LID ITSELF IS

SUFFICIENT TO EFFECT A SATISFACTORY SEAL.

4.7 Replace the Burner Shells ensuring that they locate on their

respective spigots. The seams of the Shells should be

orientated at 90º to one another to prevent a local

starvation of air.

4.8 Replace the Burner Lid.

5. LIGHTING TO CHECK SMOKE & FLUE

5.1 After checking the high and low oil flow rates:

 • Turnthecontrolknobtothemaximumsetting,6

 • Liftthelightingportcoverlocatedatthefrontofthe

burner shell

 • Insertasuitabletaperthroughthelightingporttolight

the wick. It is then important to close the lighting port

cover.

5.2 Immediately after lighting:

 • Turntheoilcontrolvalvetoitslowestsetting,1

 • Replacetheburneraccessdoor.Itisimportantthatthe

door is correctly located and sealed

 • Closetheoutercontroldoor

SMOKE TEST

5.3 Wait half an hour before carrying out a smoke test:

 • Drillaholeinthefluepipetoacceptasmokepump

probe. (This hole will require plugging after testing)

 • Samplethefumeproductsthroughtheholeusinga

Barrach smoke pump where all readings should indicate a

smoke number 0-1 at low and high fire

 • Setthecontrolknobtosetting3foraTwoOvencooker

and setting 4 for a Four Oven cooker

FLUE DRAUGHT

NOTE: ALL NATURAL DRAUGHT BURNERS DEPEND FOR

EFFICIENT OPERATION ON REASONABLE FLUE

CONDITIONS.
