Flame Calibration - Char Grill

The procedure for calibrating the Char Grill flame is outlined below.
Note: This calibration procedure should be carried out by an experienced gas
technician and is performed in situ with the system fully operational.
Before calibration, check that all other kitchen appliances connected to the main Gas
supply line are running at maximum capacity. If flame calibration of the Char Grill is
done independently of other appliances being in use, the following steps will need to be
repeated when these appliances are running to ensure the main Gas supply is capable
of the supplying the required flow.
To begin adjustment, the main Gas supply pressure should first be checked on the inlet
side of the valve to confirm that sufficient pressure is being supplied.
 Remove the control knob from the Gas control valve. This is a „press fit‟ type
knob.
 Connect a Gas pressure gauge to the test point as shown below. Test for
incoming gas pressures as listed below. (For Natural Gas, adjust incoming
pressure at supply regulator prior to Gas control valve)
 With the correct pressure at the control valve, proceed to check the High and
Low Flame settings, using the relative adjustment screws as shown below.
 When the correct flame settings are calibrated, remove the test gauge and
replace control knob.
