CLEANING AND CARE
As with all appliances, proper care and maintenance will keep
them in top operating condition and prolong their life. Your new
gas BBQ is no exception. By following these cleaning procedures
on a regular basis, your BBQ will remain clean and in good
working order with the minimum of effort.
BEWARE OF SPIDERS AND WASPS. BURNER TUBES
SHOULD BE INSPECTED AND CLEANED PERIODICALLY!
Spiders and small insects occasionally spin webs or make nests
in the burner tubes during warehousing and transit. 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 your BBQ and
create an unsafe operating environment 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. (See page 9)
To reduce the chance of FLASH-BACK , the procedure listed
below should be followed at least once a month in late summer
or early autumn when spiders are most active, or when your BBQ
has not been used for an extended period of time.
BURNER TUBE CLEANING
Follow the procedure that is most convenient for you:
1. Use a small bottle brush with a flexible handle. Run the
brush up through each venturi tube and into the burner
several times.
2. Lay the burners down with the venturi tubes facing up, and
force water through them. At this time, observe each burner
port. Make sure water comes out of every hole. If not, clean
the burners as follows
BURNER CLEANING
Regardless of which venturi cleaning procedure you used, we
recommend that you complete the following steps to help prolong
burner life.
1. Scrub the entire outer surface of the burner with a
non-metallic scouring pad to remove any loose corrosion.
2. Clean any clogged holes with a stiff piece of wire
(for example: an open paper clip).

All cleaning and
maintenance should
be carried out when
the BBQ is cool and
with the gas supply
turned OFF at the gas
cylinder.
Never attempt to
operate your barbecue
without the burner
tube being correctly
located. A serious and
immediate fire hazard
would result.
VERY IMPORTANT
The location of burner
with respect to the
orifice is vital to safe
operation. Check to
ensure the valve ori-
fices are inside of the
burner tubes before
using your gas BBQ
(See Rotary piezo
ignitor diagram). If the
burner tubes (venturi)
are not fitted over the
valve orifices and you
start lighting the burn-
ers, an explosion and
or fire might occur.
