Part Number
Definition:
A DEVICE CAPABLE OF PRODUCING HEAT FROM GAS, LIQUID FUEL, OR AN ELECTRICAL HEATING ELEMENT DESIGNED FOR PERMANENT INSTALLATION IN SHEET METAL DUCTS OF A FORCED AIR CIRCULATING SYSTEM. IT CONSISTS OF (1) A FINNED, STEEL BURNER TUBE, A COMBUSTION AIR BLOWER, A CONTROL PANEL, AND A CONSTANT LEVEL FUEL SUPPLY SYSTEM OR (2) A DEVICE HAVING A HEATING ELEMENT WHICH WHEN CONNECTED TO AN ELECTRICAL SOURCE, DIRECTLY IMPARTS HEAT. IT MAY BE PROVIDED WITH A FLANGED OUTER CASING TO FACILITATE MOUNTING IN PLANNED OR EXISTING DUCT WORK. CIRCULATION OF THE HEATED AIR IS ACHIEVED BY USE OF A BLOWER OR FAN NOT INTEGRAL WITH THE HEATING UNIT.
