STORAGE
We recommend that you minimise the exposure of the Outdoor
Range to the elements.
High moisture content in the air (rain, mist, salt spray etc.)
can affect metal components and lead to material breakdown. If
left in an area subjected to high moisture content, we strongly
recommend that you observe the cleaning procedure on a regular
basis and cover the appliance whilst not in use.
Material breakdown from high moisture conditions can be
avoided if the appliance is well protected from the weather and
regular cleaning is performed.
ANNUAL CLEANING OF THE
APPLIANCE INTERIOR
General cleaning of the Outdoor Range Barbecue will keep it
ready for instant use, however, depending on how much it is
used you must thoroughly clean the entire appliance to minimise
risk of grease fire and keep the appliance in top condition. Follow
these steps:
1. Turn all burner valves to full 'OFF' position.
2. Turn LP gas cylinder valve to full 'OFF' position.
3. Disconnect regulator from gas cylinder. Inspect hose with
regulator assembly for cracking, cuts or any other damage,
and replace as necessary. Refer to Parts List in this operator's
manual, pages 22 - 23.
4. Remove and clean cooking plates and burners.
5. Cover each gas valve orifice with aluminum foil.
6. Brush inside and bottom of the Outdoor Range Barbecue
with a fibre pad or nylon brush and wash with a mild soap
and warm water solution. Rinse thoroughly and let dry.
7. Remove aluminum foil from orifices and check each orifice
for obstruction.
8. Check each spark electrode, adjusting as needed. The
space between the spark electrode tip and spark receiver
should be approximately 4 - 5 mm.
9. Replace the burner and adjust the gas collector box. The
edge of collector box should be overlapping the burner port.
10. Reconnect gas source and observe burner flame for correct
operation.
11. Replace flame tamers and cooking plates.
M A I N T E N A N C
• BEWARE OF SPIDERS.
BURNER TUBES SHOULD BE
INSPECTED AND CLEANED
PERIODICALLY.
• SPIDERS AND SMALL INSECTS CAN
OCCASIONALLY SPIN WEBS OR MAKE
NESTS IN BURNER TUBES.
THESE WEBS CAN LEAD TO A GAS
FLOW OBSTRUCTION WHICH COULD
RESULT IN A FIRE IN AND AROUND
THE BURNER TUBES.
• THIS TYPE OF FIRE IS KNOWN AS
'FLASH-BACK' AND CAN CAUSE
SERIOUS DAMAGE TO APPLIANCE AND
CREATE AN UNSAFE OPERATING
CONDITION FOR THE USER.
• ALTHOUGH AN OBSTRUCTED BURNER
TUBE IS NOT THE ONLY CAUSE OF
'FLASH-BACK' IT IS THE MOST
COMMON CAUSE AND FREQUENT
INSPECTION AND CLEANING OF THE
BURNER TUBES IS NECESSARY.
• KEEP APPLIANCE AREA CLEAR AND
FREE FROM COMBUSTIBLE MATERIALS,
GASOLINE AND OTHER FLAMMABLE
VAPOURS AND LIQUIDS.
• DO NOT OBSTRUCT FLOW OF AIR FOR
COMBUSTION AND VENTILATION.
• KEEP VENTILATION OPENINGS OF
CYLINDER ENCLOSURE CABINET FREE
AND CLEAR OF DEBRIS.
• VISUALLY CHECK BURNER FLAMES
OCCASIONALLY TO ENSURE PROPER
FLAME PATTERN AS SHOWN BELOW.
• FAILURE TO COMPLY WITH THESE
INSTRUCTIONS MAY RESULT IN A
HAZARDOUS SITUATION WHICH, IF
NOT AVOIDED, MAY RESULT IN
INJURY.
