DoorKing 6500-480 Quick Start Manual

115 VAC - 3.3 AMP HEATER AND FAN ASSEMBLY KIT
This kit is designed for 6500/6524 model gate operators for cold weather climates where temperatures routinely drop below
40°F (4°C). A built-in thermostat will automatically control the temperature inside operator housing.
115 VAC Input Power for the 6500/6524 Gate Operator with a Heater
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.

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.
