Do I need a permit for a wood, pellet, coal stove or fireplace insert?

Yes.  Along with your permit application, you must supply the Inspections Dept. with a copy of the manufacturers installation instructions for the appliance.  The appliance must be listed and tested to UL 1482 and/or ANSI/UL 737.  Pellet stove must be listed and tested to ASTM E1509.
