Clearances to combustibles must be maintained at
all times in order to prevent the ignition of
combustible materials. In locations used for the
storage of combustible materials, signs must be
posted to specify the maximum permissible stacking height to
maintain the required clearances from the heater to the
combustibles. Signs must either be posted adjacent to the
heater’s thermostats or, in the absence of such thermostats, in a
conspicuous location. Clearances are provided on the heater’s
safety label and in the heater’s Installation, Operation, and
Maintenance manual. Product installation and operation must
comply with applicable standards, codes, and regulations. Post
this tag adjacent to the heater’s thermostat or controls before
operating the heater.

2.0 Installation •Design
Read and understand the installation, operating, and maintenance instructions
thoroughly before installing or servicing this equipment.
Design
To ensure a safe, properly designed heating system, a layout should be developed for the correct
placement of the infrared heater(s).
Aside from safety factors such as clearances to combustibles (see Chart 1.1 on page 6), consideration
should also be given to factors such as the environment (e.g., cold/drafty, average, protected), heat
coverage (sq. ft.) needed, heater centers, and the distance behind a person or work station(s). Also,
theeectiveinfraredsurfacetemperatureofapersonorobjectmaybediminishedwithwindabove5
mph. Wind barrier(s) may be required. Most importantly, clearances to combustibles must always be
maintained! Refer to hazards on page 5.
When positioning the heaters, keep in mind the location(s) of combustible materials, lights, sprinkler
heads, overhead doors, storage area with stacked materials, gas and electrical lines, parked vehicles,
cranes, etc. Refer to page 6 for minimum clearances to verify that a safe installation exists.
This installation manual, along with national, state, provincial, and local codes, addresses these issues.
It is critical that you read, understand, and follow all guidelines and instructions. Always inspect and
evaluate the mounting conditions, application, and wiring.
When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehydes,
etc.) can evaporate and/or degrade. This may result in odors or fumes being emitted into the
environment. To correct this problem, clean the area and/or introduce additional ventilation. Heaters
installed and serviced in accordance with the installation manual do not emit foul odors into the
environment.
IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater to avoid
an inadvertent discharge. This distance may exceed the published clearance to combustibles.
Certain applications may require the use of high temperature sprinkler heads or relocation of the
heaters.
Firesprinklersystemscontainingpropyleneglycol,antifreeze,orotherpotentiallyammable
substances shall not be used in conjunction with this heater without careful consideration for, and
avoidance of, inadvertent discharge hazards. For further information consult NFPA 13. Always
observe applicable state and local codes.

The heater can be suspended with chains or rigid threaded rod. Local codes or conditions that would
cause the unit to move (e.g., wind drafts, blowers, crane rails, etc.) may require rigid threaded rod.
Consult all applicable codes before installation.
The DSS series is to be ceiling-mounted only. The heater must be level from side to side and may be
0° to 45° on horizontal. Refer to Figure 2.2.
* This dimension does not include the mounting bracket. The
mounting bracket is 4” high in its vertical orientation.

Heater Installation
The mounting bracket, electrical cord (plug on 120 V models only), and screws required to install this
heater are provided with the unit. To install the unit:
1Determine the area where the heater is to be mounted. The DSS series is to be ceiling-mounted
only. Clearances to combustibles must be maintained at all times and should be taken into careful
consideration when determining the mounting location of the heater. Note: If the mounting surface
isacombustiblematerial,additionaleld-suppliedbrackets,chains,gripple,etc.mayberequiredto
maintain clearances to combustibles.
2Using a level, determine where the screw holes will need to be drilled and mark the area. Drill the
holes then place a plastic anchor into each hole before mounting the hanger using the supplied
screws.
4Verify the hanger is level. At this point, the hanger can be adjusted according to desired mounting
angle. Once desired angle is achieved, tighten the screws on the hanger.
5Wire the electrical connector according to the diagram below. A plug may be added to connect the
unit directly to a power supply. Do not install the heater directly underneath a wall plug.

Heater Usage Tips
It is important to ensure that the heater is installed properly and safely and in accordance with all local,
state, municipal, and federal laws. If unsure of the local laws governing electric heaters, contact your
localremarshal,insurancecarrier,orlicensedandapprovedelectricalcontractortoensureasafe
application and installation.
Disconnect the electrical supply when the heater is not in use.
Fluctuations in electrical voltage can reduce the life of the lamp element. Take all proper precautions
andstepstoensurethatuctuationsinvoltagedonotoccur.
Ensureheatersaremountedoutofreachofchildren,pets,andanythingelsethatmaycomeinto
contact with the lamp element(s). Do not operate the heater if the protective guard is not installed and
do not touch the lamp element. The protective guard is in place to prevent larger items from reaching
thelampelementbutsmalleritems,suchasngers,maystillbeabletopenetratetheguard,and
serious injury and/or burns can occur.
Do not put anything inside of the heater, on top of the heater, or against the heater. When the heater is
in operation, stay at least 4 feet away from the unit. Looking directly at the lamp element when the
heater is in operation for prolonged periods of time can result in damage to the eyes. Do not look
directly at the unit when the unit is in operation.
Protect the heater against shock, impact, and vibrations.
Iftheheaterisnotworking,donottrytoxtheheater.Disconnecttheelectricalsupplyandcontact
the nearest licensed electrician or electrical contractor for maintenance.
Thereectorsarecraftedfromhighlypolishedaluminumanddonotrequirefrequentcleaning.
However,shoulditbecomenecessarytocleanthereectors,followtheprocedurebelow:
• Disconnect the power supply to the heater and wait until the heater is completely cooled
down.
• Remove the protective guard.
 •Cleanthereectorwithadrycloth.
• Do not touch the lamp element with bare hands while cleaning. If the lamp is touched,
carefully wipe down with a soft cloth dipped in rubbing alcohol.
• Reinstall the protective guard.
• Reconnect the heater to the power supply.
Placementofexplosiveobjects,ammableobjects,liquids,andvaporsclosetothe
heatermayresultinexplosion,re,propertydamage,seriousinjury,ordeath.Donot
store or use explosive objects, liquids, or vapors in the vicinity of the heater.
Failure to comply with the published clearances to combustibles could result in
personal injury, death, and/or property damage.
The outside surfaces of the heater are hot during operation and after operation. If
contact is made, permanent skin damage may occur. Do not move, handle, or service
the unit during operation or while hot.
