INSTALLATION
WARNING: To reduce the risk of fire, do not store or use gaso-
line or other flammable vapors and liquids in the vicinity of
the heater.
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 and away from the side and rear.
1. Mark the intended mounting location in the base plate under the
counter or kickspace, and remove required material to provide
for easy insertion and removal of the heater cabinet.
2. The unit will be secured in place with screws through the side
angle support brackets. Provide adequate material behind side
angle support for secure mounting.
FIELD CONVERSION TO 120 V.A.C.
If a 120 V.A.C. circuit is to be used, make wiring changes as follows:
1. Disconnect white wire from heater element terminal “2” and
connect it to terminal “4.” The heater will now operate at 120
V.A.C., 750W, 6.3A.
2. For 120 V.A.C, 1500W, 12.5A operation, add the short red jumper
wire (provided) between terminals “1” and “2”.
3. Remove alarm light wire leads from terminals “1” and “3” of
the high temperature limit. Remove white wire lead from limit
terminal “1” and reconnect at limit terminal “3”. Secure wire leads
with wire tie so there is no interference with unit operation.
NOTE: Terminal numbers are marked on the side of the blower
housing, above the heater elements.
