Variable Flame Height Adjustment
(Millivolt Appliances)
All Millivolt appliances are equipped with a variable gas control valve. Flame height for these models
may be adjusted through a range between fixed low and high settings while the appliance is in
operation. Adjust the flame height as desired after lighting the appliance by rotating the variable
adjustment control knob (HI/LO) located on the front of the valve (refer to Figure 3).
