SEDIMENT TRAP ASSEMBLY
To Connect the Direct Wired Thermostat Kit to the Control
Box on the Heater:
1. The installation and wiring of a thermostat must be
done by an authorized electrician.
2. The thermostat cordset must use a minimum of 18
gauge wire consisting of a hot lead, neutral lead, and
a ground lead.
3. Disconnect the brown and white wires at the six wire
terminal block on the ignition controller. Connect the
thermostat wiring between these two wires. Refer to
the heater’s electrical connection diagram for
thermostat connection.
4. The heater must be tested for proper operation after
the thermostat has been connected.
WARNING
Electrical Shock Hazard
■
Disconnect the electrical supply before connecting the
thermostat to the heater.
■
Failure to follow this warning can result in electrical
shock, leading to personal injury or death.
THERMOSTAT INSTALLATION
The heater shall be connected to an approved electrical
supply by an authorized installation agency.
An electrical disconnect such as a circuit breaker should
be installed to allow shut-down of the heater in the event
of servicing, maintenance, or repair.
The heater’s power cord is wrapped around the motor
at the end of the heater opposite the gas inlet end of
the heater.
Unwind the cord and route it through the case for
connection to an approved electrical supply. See image
to the right
.
ELECTRICAL CONNECTIONS
The heater’s gas hose and regulator is not supplied by the
L.B. White Co. The regulator and hose shall be supplied by
an authorized gas installation agency.
The gas hose and regulator shall be of proper diameter
and capacity to provide required gas supply pressure to
the heater. See page 4 of this manual for required gas
pressures.
