DANGER
!
ELECTRIC SHOCK OR FIRE HAZARD
The wire and breaker sizing chart will give a general rule of installation
size. If you have long distance wire runs, larger size wire is required
due to voltage drops. Consult an electrician if you are not knowledgea-
ble about wiring codes.
Wiring
Branch Circuit Connection
1.
Connect heater only to the voltage, amperage and frequency
specified on the nameplate.
2.
Wiring procedures and connections shall be in accordance with all
National and local codes having jurisdiction.
3.
Removing the two screws on the bottom of the heater will allow
you to gain access to the wiring compartment.
4.
A knock of 1/2 inch (12.7 mm) conduit size (7/8 inch) is provided
in the back of the heater for power to enter. Provide proper con-
duit connectors for your flexible connections.
5.
Wires will be placed in the terminal block lugs labeled L1 and L2
and tightened to 35 lbs. of torque. Lugs are approved for copper
or aluminum conductors from # 14 to #2 AWG. Minimum 600 volt
60 degree C wire is required. Copper wire is recommended. Fig.
4.2
6.
Attach ground to the green wire with a wire nut.
7.
Assemble all covers on electrical and apply power. Test unit by
turning thermostat up past room temperature. You will see a puff
of smoke as the elements are energized and the fan turns on. This
is a normal burn off of manufacturing lubricants and will dissapate
in 5 minutes.
8.
Heater will continue to run until the room temperature you set is
reached and then turn itself off until the temperature drops again.
9.
CAUTION - High temperature. Risk of fire, keep electrical
cords, drapery, furnishings, and other combustibles at least 3 feet
(0.9 m) from the front of the heater as well as away from the side
and rear. To reduce the risk of fire, do not store or use gasoline or
other flammable vapors and liquids in the vicinity of the heater.
