VALVE ADJUSTMENTS
The valves on your Hestan grill are preset at the factory for optimum performance. However, the
low setting on these valves are adjustable if altitude, low-heat performance, converting from one
gas to another, or other factors indicate an adjustment is needed. It is not recommended to adjust
the Rotisserie or Sear Burner valves.
NEVER ADJUST THE BURNER SO LOW THAT IT MAY GO OUT DURING USE.
DO NOT OPERATE THE GRILL WITH THE LOW HEAT SCREW REMOVED. GAS
CAN ESCAPE AND CAUSE A POTENTIALLY HAZARDOUS CONDITION.
ADJUSTMENT STEPS:
1. Remove the control knobs, drip tray, and control panel from the unit.
2. Follow lighting instructions by setting the control knob on “HI” and allow the burner to
preheat for 10 minutes.
3. Turn the control knob to “LOW” and wait for the burner temperature to drop and stabilize,
about 10 minutes. Attempting adjustment at any setting other than LOW can create a
dangerous condition.
4. Insert a small flat-blade screwdriver into the valve stem to begin the adjustment
(see Fig. 5). The screw only has 2-3 complete revolutions of adjustment. After this, the screw
may continue to turn, but is actually coming out of the valve and could result in a gas leak. DO
NOT turn more that 3 revolutions!
5. Turn counter-clockwise very slowly to INCREASE the low flame. The flame will take a few
seconds to respond to the adjustments you are making.
6. Adjust the flame so the burner is still fully lit on all ports, without fluttering or going out. Turn
off the burner and re-light. Check the new low setting once again to assure proper adjustment
is reached. Reattach the control knob.
