Thermostat - Brant Radiant Heaters DX3L Series Manual

3.0 Installation •

Thermostat

The power supply to the heater must be within +/- 5% of the voltage rating as indicated on the rating
plate of the appliance. If input power does not meet these specifications, contact your utility company.
A means shall be provided to disconnect the heater from all ungrounded conductors, and is
recommended to be located within 5 feet of the service access panel. If conditions do not allow for this,
then the branch-circuit switch or circuit breaker shall be permitted to serve as the disconnecting means
where the switch or circuit breaker is within sight from the appliance or is lockable in accordance with
the National Electrical Code.
The main electrical supply enters at the rear of the heater utilizing 1/2" electrical knock-out. When
routing the electrical supply conduit to the unit, ensure that it does not interfere or obstruct the heater's
service access panel.
Thermostat Connection
NOTE: Different thermostats operate according to their particular features. Refer to the thermostat's
specifications for details.
Prior to connecting the thermostat wire to the heater, check to make sure the wires will be long enough
to allow for the heater to freely expand and contract without causing undue strain on the wires or
terminal. Use 18 gauge wire (or larger) that is suitable for a NEC Class 2 rating for thermostat
connections.
Each DX3L series heater requires a thermostat rated for 24 VAC to operate. The heater comes standard
with a terminal strip for making the thermostatic connection, located on the back panel.
Edges of sheet metal holes may be sharp. Use gloves as a precaution when
routing wires.
