Part 4   Operation 



If pre-melting of shortening is not possible, 
cut the shortening into pieces and 
packed down into the tank. 



Bringing the shortening up to frying 
temperature, when not pre-melting, 
should be done in two stages. 

 
Pre-Heating

; 

Light the main burner and manually cycle the 
burner ‘On’/ ‘Off’ until the shortening has 
liquefied.  Ideally the main burner should be 
cycled ‘On’ for 5 seconds and ‘Off’ for 10 
seconds. 
Following this procedure should allow 
shortening to liquefy gradually without 
scorching. 
Once the shortening has liquefied, it can be 
brought up to fryer operating temperature. 

NOTE: 

Running burner continuously will cause 
shortening in contact with tank to overheat, 
resulting in premature oil breakdown.  Never 
allow shortening to smoke while melting as 
this indicates that the temperature is too high.  
If the shortening starts smoking, increase the 
‘Off' intervals of the main burner. 

Lighting the Pilot Burner 

1.  With the fryer tank full of frying medium, the pilot 

burner can be lit. 

2.  Check that the gas supply is turned ‘On’ at the 

mains supply. 

3.  Open the access door at front of fryer to access 

the control panel. 

4.  Rotate gas control knob to the pilot position and 

hold the gas control knob depressed. 

5.  Manually light the pilot burner through the Pilot 

Burner Viewing Opening. 

6.  Continue holding Gas Control Knob depressed 

for approx. 10 to 15 seconds after igniting pilot 
burner, then release, pilot burner should remain 
alight. 

7.  If the pilot burner does not ignite, repeat Items 1 

to 6 above. 

Before Use 

1.  Check that the gas supply is turned ‘On’. 
2.  Check that there are no foreign articles in the 

tank. 

Filling the Tank 

NOTE: Blue Seal fryers can be used with both oil and 

shortening. 

1.  Before filling the tank, always check that the 

drain valve, behind the access door, is closed.  
A locking slide is provided on this valve and this 
should always be locked in position during use. 

a. 

OIL 

- Carefully fill fryer tank with oil until the 

'FILL-LEVEL' mark is reached.  The Blue Seal 
fryer will hold 18 litres of oil (32lbs shortening). 

b. 

SHORTENING 

- Ideally shortening should be 

pre-melted prior to putting it into the tank.  
This is normally done in a suitable vessel on a 
boiling table burner.  Liquefied shortening 
can then be poured into the tank until it 
reaches the 'FILL LEVEL' mark. 



When pre-melting shortening, only heat 
until the shortening is just liquefied.  

Do not 

bring up to high temperature as handling 
of hot shortening is dangerous

.

GREAT CARE MUST BE TAKEN BY THE OPERATOR TO USE THE FRYER SAFELY TO GUARD AGAINST THE RISK OF FIRE.
