2. Advice  the  User  that,  for  continued  efficient  and  safe  operation  of  the  appliance,  it  is  important  that

adequate servicing is carried out at regular 6 monthly intervals.   

3. Hand the User Instruction to the User and demonstrate the correct operation of the appliance and system

METHOD OF APPLIANCE CONTROL

" below.  

METHOD OF APPLIANCE CONTROL

 

An individual controlled oil burner provides heat to the two ovens, hotplate and domestic hot water. 

Appliance controls are incorporated at the left-hand side of the cooker. 

Oil Burner - 

See Fig. 11

 

The burner must be lit manually with a lighted taper to establish itself at low fire rate i.e. with the control knob set
to No.1 position. Oil flow (heat input) is increased by manually turning the control knob to a higher number setting, 
to control the desired oven temperature. 

No.1 position is the minimum (and idling) rate and setting No.6 is the maximum (and High) rate. 

Before  the  temperature  is  attained,  turn  the  knob  setting  down  to  suit  the  oven  load  and  temperature
requirements. 

When not in use, set control knob to No.1 setting. 

NOTE: 

THE BURNER IS INTENDED TO RUN IN A CONTINUOUSLY ALIGHT POSITION AT ALL TIMES -AT A

LOW  POSITION  WHEN  NOT  USED  FOR  COOKING,  THEN  TURNING  TO  THE  APPROPRIATE  NUMBER
WHEN  REQUIRED,  TURNING  OFF  THE  COOKER  IS  NOT  RECOMMENDED,  UNLESS  SERVICING  IS
REQUIRED. 

NOTE

: SMOKE/SMELL EMITTED DURING INITIAL USAGE 

Some parts  of  the cooker have been coated with a light covering  of  protective oil. During initial operation of the
cooker, this may cause smoke/smell to be emitted and is normal and not a fault with the appliance, it is therefore
advisable  to  open  doors  and  or  windows  to  allow  for  ventilation.  Lift  the  insulating  lids  to  prevent  staining  the
linings 

LEAVE THESE INSTRUCTIONS WITH THE

 

USER FOR FUTURE USE

 

SERVICING INSTRUCTIONS 

BI-ANNUAL SERVICING

 

It  is  important  that a  6  monthly service be  carried  out  by  a  competent Service  Engineer  and  it  is  recommended
that a contract be made with such an Engineer. Your Rayburn Stockist will provide advice on the location of the
nearest Servicing Engineer. 

With normal use, a boiler/cooker annual flueway clean and burner maintenance should be carried out immediately
before and after the end of the heating season. An additional cooker flueway clean, halfway through the heating
season, may be necessary in some cases. 

The householder should be advised to turn OFF 

the cooker oil valve control knob, the night preceding the day

of the service, so that the appliance will have cooled down by the following morning, in readiness for servicing.
