Step 10. Install the field-provided ON/OFF switch in a convenient  
location on a wall, near the fireplace.  
IMPORTANT: Ground lead must be connected to the green screw

appliance from operating. The appliance must be electrically  
grounded in accordance with local codes or, in the absence of local  
codes, the National Electrical Code, ANSI/NFPA 70-(latest edition).
