I. Heat Management
The NNXT models have a variable burn rate which is
controlled by the remote control. Therefore the flame
height is adjustable.
The flame height may be adjusted as desired by locating
the flame option on the remote control and adjusting up
or down to desired flame height.

Follow the initial break-in procedure below to cure the
materials used to manufacture the fireplace and the
finishing materials around it.
