7. SERVICE

FOR YOUR SAFETY, ALL SERVICE WORK MUST BE CARRIED OUT BY AN AUTHORISED
PERSON AND USE ONLY ORIGINAL SUPPLIED AND SPECIFIED PARTS.
TEST ALL FITTINGS, PIPES AND PIPE CONNECTIONS FOR LEAKS IN ACCORDANCE
WITH APPROVED GAS LEAK TEST PROCESSES AND METHODS. DO NOT USE A FLAME.

7.1 RECOMMENDED SERVICE

It is recommended that your appliance be serviced by an authorized person every 12 months. This period is for
guidance purpose only and may vary based on usage of the equipment and operator care. Prescribed service
tasks include;
• Functional test of all components and clean and adjust as necessary.
• Inspect and clean all gas valves and lubricate with an industry approved lubricant.
• Inspect all gas piping.
• Check and adjust specified gas pressures.
• Leak test.
• Full operational, performance and safety test.

7.2 BURNER ADJUSTMENTS

Leak Test
1) Ensure that all control valves are in the OFF position.
2) Turn on the main gas supply valve.
3) Light all pilots.
4) Leak test all valves and fittings using approved methods.
5) Correct any leaks as required and re-check.
6) Shut off all valves and set the control knobs to "OFF" position.
Test Point Pressure
The pressure test point is located on the gas manifold. The gas manifold and pressure test point is accessed by
opening the fryer door. The test point pressure is shown in the 'Nominal Gas Consumption Table' and is set with
the burners operating at maximum setting.
Pilot Burner Adjustment
Set all pilots so that the flame envelops the tip of the thermocouple by adjusting the pilot flame adjusting screw
on the gas valve - clockwise to decrease, or counter clockwise to increase.
Service adjustment should not be necessary unless you're changing the gas valve or performing a gas conversion.
Burner Adjustment
The burner orifices are fixed as specified and cannot be adjusted. The specified gas rate will be achieved if the
gas supply pressure and test point pressure is correct.
A distinct blue flame over the entire port area of the burner will be achieved at full rate when the air supply is
correct and the injector and burner are properly aligned.
If the flame is yellow and wavy, the cause needs to be established.
WARNING: If you are not competent in performing any service task or require assistance, please contact your
