ELECTRICAL/CONTROLS
ELECTRICAL REQUIREMENTS
120VAC / 60 Hz / Single Phase / 1A / 3 Wire Grounded
Starting Current: 3 amps
Running Current: 1 amp
1. Electrical installation must be grounded in accordance with CSA Standard C22.1
part 1 in Canada or The National Electrical code ANSI NFPA 70 (latest edition) in
the United States.
2. Polarity of line voltage and neutral wires must be maintained.
3. The total load of all heaters in a circuit must be considered so as to not overload
the circuit.
4. Ensure that thermostat wire polarity is maintained.
THERMOSTAT CONTROL
Heaters are designed for compatibility with either 120 Volt (line) thermostat controllers
or 24 Volt thermostat controllers. For use with 120 Volt controllers, the heater must be
plugged into a “switched” 120 Volt duplex receptacle, where the receptacle is switched
by the thermostat controller. Heating zones may be established where one 120 Volt
thermostat controls more than one heater, provided the total heater electrical load does
not exceed the maximum allowable amperage on the circuit.
For a 24 volt thermostat control, plug the heater into a 120 Volt duplex receptacle.
Remove the jumper wire on the control box marked “24 Volt thermostat” and connect
the thermostat wire to the terminals.
Do not allow live thermostat wires to contact
appliance chassis, or damage to the appliance transformer/controls may occur .
Ensure that if the thermostat has a heat anticipator, the heat anticipator is set at
maximum. When using a 24 Volt thermostat, only one heater may be directly controlled
by one thermostat unless a system of field supplied relays are utilized.
For 2 stage appliances, connect wires as marked on appliance terminal. Polarity must
be maintained. If required, connect thermostat ground to appliance ground post.
