The fan is thermostatically controlled and
it will not operate if the appliance is cold.
A few minutes after the appliance is lit and
the variable speed control is set at a desired
setting, the fan will automatically turn on.
The fan will automatically turn off after the
appliance has cooled down.
The fireplace must be electrically grounded
in accordance with local codes or, in the
absence of local codes, with the current
Canadian Electrical Code CSA C22.1, or The
National Electrical Code ANSI / NFPA 70 in
the US. This appliance must be connected
to a line-voltage electrical supply.
WARNING: The electrical grounding
instructions must be followed. The fan kit
is equipped with a three-prong (grounding)
plug for your protection against shock
hazard, and should be plugged directly into
a properly grounded three-prong outlet. DO
NOT cut or remove the grounding prong
from this plug.
