1.0 About your HotZONETM HeatProjector
Congratulations on your purchase of a revolutionary HotZONETM HeatProjector from Radiant Op-
tics. The HeatProjector line of electric infrared heaters are the most efficient spot heaters on the
market today – and not by just a little bit. Our high efficiency heat “projector” is made possible by
the combination of two proprietary and innovative features. Infrared heat is generated with our
unique Inverted Cone IR element and focused using our precision Compound Reflective Lens.
These act to generate, collect, and concentrate heat rays into a beam that can be pointed at a tar-
get area.
HotZONEM HeatProjectors come in 2 models: HZEHPe7500w and HZEHPe15000w
The e7500 delivers the equivalent energy of a 7500w non-lensed heater with only 1500w input;
The e15000 delivers the equivalent energy of a 15000w non-lensed heater with only 3000w input.
HeatProjectors are very low cost to run, have a smaller carbon footprint and can deliver a beam of
heat to a target over a longer distance and with a defined edge between the heated and unheated
areas.
Plan your installation by identifying the area you want to heat and how much of a temperature
increase is desired. The temperature increase depends on the power of the heater, the mounting
angle, and the distance from the target. See the HZE HeatProjector Product Guide available at
www.radiantoptics.com and refer to the Temperature Increase Map.
HotZone™ electric heaters are listed with ETL and ETLc (for Canada) by Intertek and are approved
for use in dry and wet locations.

3.0 Mounting and Electrical Installation
3.1 Mounting
Mount the heater according to the following installation instructions:
1. Mount the heater at or above the MINIMUM MOUNTING HEIGHT (See Table on page 5)
2. Ensure the MINIMUM DISTANCE TO COMBUSTIBLES is maintained above, below and around the
heater. (See Table on page 5)
3. There are several methods for mounting your HZE HeatProjector. Each HZE HeatProjector comes
with a 3/4” EMT compression fitting and enough high temperature lead wire for mounting at the
minimum distance to combustibles.
Options:
a. Use 3/4” EMT conduit
(1) Radiant Optics recommends using the 3/4” EMT compression fitting provided to mount
your heater using 3/4” EMT conduit.
(2) Enough high temperature lead wire is provided to mount the heater at the minimum dis-
tance to combustibles: 6” for the HZEHPe7500 model and 9” for the HZEHPe15000 model.
Additional lengths of lead wire and ground wire can be attached to the wires provided using
a butt splice or connection inside a conduit body. Splices must be done per the NEC and local
codes.
(3) Comfort is best obtained with the heater off to one side and angled at 30º. Straight EMT
from heater to wall or ceiling will give a 45º mounting angle. Bend EMT as necessary to attain
desired mounting angle.
b. Use chains and flexible conduit
(1) the heater can also be hung by 4 corners using chain. Connect chain to the heater lip by
drilling 4 holes for hooks or attach chains mechanically. Position the heater to obtain a
mounting angle between 20º and 45º.
(2) Use metal flexible conduit to electrically connect leads per NEC and local codes.
c. Optional Mounting kits from Radiant Optics—Radiant Optics offers several different mount-
ing kits for both wall and ceiling mounting as well as in-ceiling mounting options (continued
on next page).

The Radiant Optics HeatProjector projects a beam of energy at a target area. Items placed too
close to the heater can overheat and can catch fire. Installers must mount the heater at or
above the MINIMUM MOUNTING HEIGHT and ensure the MINIMUM DISTANCE TO COM-
BUSTIBLES is maintained above, below and around and the heater. (See Table on next page)
1. At minimum distance to combustibles, heaters will not raise the temperature of a highly
absorptive surface >90° F
2. Many heater manufacturers exaggerate the minimum distance to combustibles to exag-
gerate the performance of their heaters. Our distances are true minimums.
3. The bulk of the heat radiates from the lens of the heater in a heat beam and care must be
taken to keep combustibles out of the Combustible Avoidance Zone

3.2 Electrical
All wiring must be in accordance with the National and Local Electrical Codes. The heater housing must be properly
grounded. Refer to the label on the heater for model identification.
1. Install circuit protection for each heater or bank of heaters as required by the NEC and local codes.
2. Connect the service to the heater with properly sized conductors. Use waterproof conduit or flex if installed out-
doors or in wet areas.
3. Use high temperature grounding lead (identified with green tape) to connect to ground per NEC and local codes.
4. Connect service to the high temperature wires according to the wiring schematics below. Heaters have two, three
or four wires with the neutral and/or ground marked accordingly.
5. Supply heater control equipment as required to turn heaters on and off. Consider additional controls to allow the
heater to a) come on in stages for heaters with staged elements b) be dimmed or c) be controlled by timers.

4.0 Maintenance
HotZone™ heaters have no moving parts and require very little maintenance. We recommend the
following be done at least once a year:
• With an air hose regulated to 30 psi or less, blow off any dust and dirt that has accumulated on
the reflective surfaces of the heater and reflective lens. Accumulated dirt can degrade perfor-
mance .
• Blow off any accumulated dirt on the vent gaps of the heater and make sure the cover is not
bent such that the vent area is reduced.
• When not installed or in use, store the heater in a dry, dust-free place and be sure the lens as-
sembly is protected from any possible damage.
5.0 Troubleshooting
At full power and after two to three minutes of warm-up time, the heater element should glow a
warm orange color, similar to the color of coals in a hot fire.
If the element does not warm up at all:
• Check that the power is on at the circuit breaker and/or any installed switch or dimmer.
• Check that the element has not failed. Burned out elements normally have visible burn marks
on the face of the element. If there is no evidence of damage, and you still suspect the element,
turn off the power at the circuit breaker, disconnect the service power and check element re-
sistance. It should be between 10 and 50 ohms, depending on the element.
If the heater barely glows:
• Check any installed dimmer is turned full on and operating correctly,
• Check for the correct line voltage (under load condition).
• Confirm the heater is wired correctly. See Wiring Diagrams.
If the heater glows a bright orange-white, and heats up very quickly, the heater is receiving
too much power and will burn out very quickly if it is not turned off.
• The line voltage is too high.
Lens Repair
Heater lenses are manufactured from thin aluminum and are easily bent and damaged. Heater
performance deteriorates when the lenses are bent or damaged. In most cases the lenses can be
bent back into shape by hand or with pliers. If the lens cannot be repaired, it can be replaced.
