ARNING
The dimensions shown in Figures 4 through 12 and defined in the fireplace
manufacturer's instructions are
minimum clearances

the front of the heater.
When heater is installed into a ventless firebox, minimum clearances, as
specified by the ventless firebox manufacturer, must be met.
Follow these instructions carefully to ensure safe installation. Failure to
follow instructions exactly can create a fire hazard.
