INSTALLATION
WARNING:
Risk of personal injury
Installation procedures must be performed by a qualified technician with full knowledge of all applicable electrical codes.
Failure can result in personal injury and property damage.
IMPORTANT:
If necessary, contact a licensed electrician to install an appropriate 15 amp electrical circuit with correct NEMA receptacle.
DO NOT use an extension cord.
CAUTION:
Electrical Shock Hazard
The ground prong of the power cord is part of a system designed to pro­tect you from electric shock in the event of internal damage.
DO NOT cut off the large round ground prong or twist a blade to fit an existing receptacle.
Location
For proper operation and maximum performance, locate the unit in an ambient air temperature of 70F (21C).
Avoid placement in areas near exhaust fans where there are active air movements.
For safe operation, locate the unit at least 2” from combusti­ble walls and materials, on a solid level surface.
GROUNDING INSTRUCTIONS
This appliance is equipped with a cord having a grounding wire with a grounding plug which must be plugged into an outlet that is properly installed and grounded. In the event of an electrical short circuit, grounding reduces the risk of elec­tric shock by providing an escape wire for the electric current.
WARNING—Improper use of the grounding can result in a risk of electric shock. Consult a qualified electrician or
serviceman if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded.
IMPORTANT: Not under warranty:
Damage to unit due to being connected to the wrong voltage or phase is NOT covered by warranty.

NORMAL OPERATION
THERMOSTAT CALIBRATION
If additional heat range is required in the cabinet, unplug the heating unit, remove the thermostat knob, insert a small straight blade screwdriver into opening in center and turn limit control set screw counter-clockwise one full turn. See diagram on left.
Replace thermostat knob and turn clockwise to reach new maximum temperature. Repeat this until desired tempera­ture is reached. Each 1/4 turn of the calibration set screw will raise the element heating capacity by approximately 25­35ºF.
If a reduction of heat is desired, turn limit screw clockwise one full turn. Hold the door open allowing unit to cool until inside temperature is below the desired temperature. Close the door and allow unit to rise to a new maximum temperature. Repeat this until desired temperature is reached.
THERMOMETER CALIBRATION
Place an oven thermometer or accurate temperature meter in the geometric center of the cabinet. Power heating sys­tem up and turn thermostat clockwise, to maximum setting and wait approximately 45 minutes.
Open the door and check inside thermometer temperature. In recalibration is required, pry the plastic cover off the dial body and with a small flat blade screwdriver, insert into the pointer as shown.
Carefully turn the pointer with your finger to match the sta­bilized internal temperature. Be careful not to bend the pointer, as it is very fragile.
