tank. The regulator contains a flexible
diaphragm and should not be allowed to touch
the grill body or its surroundings.
8. Ensure that the burners and drip tray are clean
and free from obstructions.
LP (PROPANE) UNITS
· Is the cylinder almost empty? Almost-empty
cylinders may not have sufficient pressure
to run the burners at high heat. Have the line
pressure checked by a qualified technician.
· Flow Limiting Device - improper lighting procedures
may have activated the LP cylinder's flow control
device, reducing the heat output. These are a built-
in safety check valve that prevents the fuel from
being supplied (or may reduce the gas flow). The
check valve is there to detect hazardous leaks in
the system. If there is a leak, the drop in pressure is
detected, and the tank goes into check, which
restricts or stops the gas flow. This will make the
cylinder appear to be empty. See below on how to
reset the flow control device valve.
TO RESET THE FLOW CONTROL
1. Shut OFF all burner control knobs and close the
valve on the LP cylinder.
2. Wait 30 seconds and then very slowly, reopen
the cylinder valve.
3. Wait a few seconds and re-light a burner.
BULK LP TANK USERS
Bulk LP cylinder lines must be properly regulated.
Ensure that you are using a 4/11 appliance
regulator converted to LP gas. Also ensure that you
do not have more than one regulator in-line.
NATURAL GAS UNITS
1. Make sure that the supply line is at least 3/4"
ID (inside diameter) or 1" OD (outside
diameter).
2. Check line pressure, natural gas inlet pressure
should be at least 5" W.C. and manifold
pressure not less than 4" W.C. under full load
(with all burners on).
3. Check burners for blockages.
4. Check flame characteristics.
5. Clean or adjust air shutter. See 'Adjust the Air
Shutter' in the section entitled
'TROUBLESHOOTING GUIDE'.
BURNER GOES OUT
1. First determine if the location of your grill is
causing the problem.
2. If the grill is subject to high winds, reposition it
to provide some protection.
3. Check the gas supply and flame characteristics.
See 'Adjust the Air Shutter' in the section
entitled 'TROUBLESHOOTING GUIDE'.
4. Check to ensure that the burners are correctly
positioned in the grill. See 'Cleaning the
Burners' in the section entitled 'CLEANING
YOUR GRILL' for further details.
BURNER GOES OUT ONLY WHEN SET TO "LOW"
The burner valves on the grill feature an adjustable
low setting. Fluctuations in gas pressure, gas
conversion and even in the quality of the gas itself
may affect burner performance at the LOW setting.
It could be either too high or too low. Please see
'Low Heat Burner Adjustment' in section entitled
'FINAL CHECKS' for further information.
IF YOUR GRILL DOES NOT LIGHT IN 4 TO 5
SECONDS, you may need to purge the line. See
'Gas Line Purging' in section entitled 'GAS
CONNECTIONS' for further details
