continuous operation without receiving a command from
the remote control. If this occurs, restart the appliance.
H. Heat Management
Heat Output
The Mercury models have a variable burn rate which is
controlled by the HI/LO knob on the gas valve. Therefore
the flame height is adjustable. The HI/LO knob is shown
in Figure 3.6. It is located in the control cavity of the
appliance. The HI/LO knob may be adjusted as desired
by turning clockwise to the HIGH position and by turning
counterclockwise to the LO position.
If an optional fan is installed, the fan speed is controlled
by adjusting the speed control knob. Turn the knob to
increase the fan speed as desired.
