115 VAC - 3.3 AMP HEATER AND FAN ASSEMBLY KIT

DoorKing Part Number

6500-480

This kit is designed for 6500

/6524

 model gate operators

 f

or cold weather climates where temperatures routinely drop below 

40°F (4°C). A built-in thermostat will automatically control the temperature inside operator housing.

DO NOT

 use the “high voltage wire size and distance requirements” table in the Installation/Owner’s manuals to determine the high 

voltage AC input power wire size and distance requirements for the gate operator because of a 

much greater

 current draw when 

using the heater. Use the table below to determine the wire size and distances for your chosen gate operator when a heater is 
installed. The primary operator should have a 

“Dedicated”

 circuit breaker at the power source.

If the high voltage AC input power wiring is greater than the maximum distance shown, it is recommended that a service feeder be 
installed. When large gauge wire is used, a separate junction box must be installed for the operator connection. Wire run distances 
are based on NEC guidelines for copper wire allowing a maximum 3% voltage drop on the line. The calculated distance was then 
further reduced by 10% to allow for other loses in the system. 

Never 

run low voltage rated wire insulation in the same conduit as 

high voltage rated wire insulation.

 Gate Operator with a Heater

Wire run distances are shown for ONE gate operator with heater. In bi-parting (dual) gate

applications, reduce the distance by one-half.

DO NOT USE THIS HEATER KIT IF THE 6500 OPERATOR IS POWERED FROM THE 2600-266 HIGH 

VOLTAGE KIT

, OR IF THE 6524 IS POWERED FROM A 230 VAC SOURCE

.  THIS HEATER KIT CAN 

ONLY BE USED WITH OPERATORS POWERED DIRECTLY FROM A 115 VAC SOURCE.
