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 replace must be electrically connected and
grounded in accordance with local codes or, in the
absence of local codes, with the current CSA C22.1
Canadian Electrical Code Part 1, Safety Standards
For Electrical Installations, or The National
Electrical Code ANSI / NFPA 70 in the US.
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.
