• Burn Rate
The Novus direct vent 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 3.5. It is located in the control cavity
of the appliance.
The HI/LO knob may be adjusted as desired by turning
clockwise to the HI position and by turning counterclockwise
to the LO position.
• Change fan speed
If an optional fan is installed, follow the instructions
included with the fan.
