IMPORTANT INSTRUCTIONS
When using electrical heating appliances, basic precautions should always be followed to
reduce the risk of fire, electric shock and injury to persons, including the following:
1. Read all instructions before wiring or using this heater.
2. Heaters outlet grill is very hot when in use. To avoid burns, do not touch hot surfaces with bare skin.
Keep combustible materials, including furniture, pillows, bedding, papers, clothes, curtains, and boxes at least three feet (.9 m)
from the front of the heater and keep them away from the sides and rear.
3. Do not use outdoors.
4. Heater is not intended for use in bathrooms, laundry areas or similar indoor locations.
Never locate heater where it may fall into a bathtub or other water container.
5. Do not insert or allow foreign objects to enter any inlet or outlet openings as this may cause an electric shock,
fire, or damage to the heater.
6. To prevent a possible of fire, do not block air intakes or exhaust in any manner.
7. Heater has hot surfaces. Internal thermostat and limiting parts will arcing or create sparks inside. Do not use this heater in areas
where gasoline, paint, or flammable liquids or gases are used or stored.
8. Use this heater only as described in this manual. Any other use is not recommended by the manufacturer
and may cause fire, electric shock, explosion or injury to people and or property.
9. If heater shows signs of overheating immediately turn the circuit breaker off to the heater. Remove and inspect for any objects
on or adjacent to the heater that may cause the high temperatures. Have a professional Inspect the internals until the reason
is clear why the heater is overheating. Do not reinstall until it has been professionally serviced.
10. Do not operate heater after it malfunctions. Disconnect heater at service panel and have heater inspected by a reputable
electrician before reusing. To disconnect heater, turn controls to off position, and turn off power to heater circuit at main
electrical panel or operate internal disconnect switch to off if provided.
11. Extreme caution is necessary when any heater is used by or near children or invalids and whenever the heater is left

General information and Guidelines:
Heater is intended for garage shop and studio heating of large areas from 400 to 1250 square feet depending on your location and
climate. Colder climates require more heat or wattage per square foot than warmer climates. In some cases it may be necessary to
use multiple units to obtain ideal temperature control. If more than one unit is required. Arrange the heaters so they create a circular
air pattern around the outside of the room, or across the coldest walls.
Insulation will aid in retaining heat provided by your new heating system, and will reduce energy costs associated with heating.
The thermostat in the EKB has a range from 40 to 90 degrees with a freeze protection setting of approximately 50 degrees. Freeze
protection temperature is approximate and should be verified with the digital thermometer if is important that freeze protection is
critical or a potential freeze could cause damage. The heater is equipped with a bracket that allows it to be mounted to either the
ceiling or the wall. The heater can then be tilted 25 degrees to direct heated air towards the floor. Never point at the ceiling, toward
other appliances or objects that obstruct the airflow, or toward objects that could be damaged by excessive heat or have the potential to catch fire due to prolonged exposure to heat. Following these simple guidelines will have provide you with a comfortable safe
heating system for years to come.
Heater inner workings:
The EKB cast aluminum motor incorporates a large oil reservoir that is maintenance free and recirculates the oil across the shaft at a
rate of 5 drops per minute. The motor is Thermally protected for safety. The 80/20 Ni-Chrome elements allow for quick heating and
cooling type leaving all the heat in the room by time the fan stops. A self-holding over-temp limit is provided on each element as well
as one main self holding limit located between the elements for total shut off. If the total heater shut off limit trips the heater is disabled until the power to the heater is shut off for 10 minutes at which point it will reset. There is no fan delay on start up or shut off
so no special complicated feed wiring is required for remote thermostat connections. (i.e. switch loops circuits).
Operation:
The EKB heater requires mounting in a clear, open-air location for optimal performance.
Heater should be installed in a location that is clear and will remain of storage items. The heat outlet of the unit should be able to
push warmed air to the far side of the room. Ample space should be left behind the heater to allow air to be drawn in through the
back of the unit. Clearance recommendations within these instructions are the minimum, providing more space will result in improved
airflow and safer operation.

Motors are maintenance free and do not need to be oiled. Heater will need to be blown out and cleaned every year, in order to be
kept free of all dust, dirt and fibers that may accumulate. Use compressed air to free up any particles that may have entered the
heater. Fan blades should be clean and able to move freely. Wipe both the front and rear grills and continue to keep clear all debris
and wiped clean with a soft towel.
