Combustible Items Include: Moving Objects Include:
• Wood • Overhead doors
• Paper • Vehicles on lifts
• Fabric • Cranes
• Chemicals • Hoists
• Wall or roof insulation
• Plastics
When installing the infrared heater system, the minimum clearances to combustibles must be
maintained. These distances are shown in Chart 1.5 and on the heater. If you are unsure of the potential
hazards,consultyourlocalremarshal,reinsurancecarrier,orotherqualiedauthoritiesonthe
installation of infrared heaters for approval of the proposed installation.
A critical safety factor to consider before installation is the clearances to combustibles. Clearance to
combustiblesisdenedas
the minimum distance you must have between the indicated surface and
the combustible item
. Considerations must also be made for moving objects around the infrared heater.
The following is a partial list of items to maintain clearances from:
Hazards Include:
For maximum safety the building must be evaluated for hazards before installing the heater system.
Examples include, but are not limited to:
• Gasandelectricallines
• Combustible and explosive materials
• Chemical storage areas
• Areas of high chemical fume concentrations
• Provisions for accessibility to the heater
• Adequate clearances around air openings
• Vehicle parking areas
• Vehicles with lifts or cranes
• Storage areas with stacked materials
• Lights
• Sprinkler heads
• Overhead doors and tracks
• Dirty, contaminated environment
Signs shall be posted specifying the maximum permissible stacking height in order
to maintain clearances to combustibles.
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.

* Heaters mounted on an angle between 0° and 45° must maintain clearances posted for 0° or 45°,
whichever is greater.
** Clearances to combustibles must be maintained when using recessed mount kits (P/N: ELx-FRxx). For
additional information, refer to form # LSH123a - Recessed Mounting Frame Installation Instructions
or contact the factory.
NOTE: Ensure that building materials with a low heat tolerance (i.e, awnings, fabrics, plastics, sprinklers,
insulation, etc.) are protected against degradation. This may require the heater to be mounted at a
distance in excess of the published clearances to combustibles. Contact the material manufacturer for

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, operation, 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 1.5 on page 8), consideration
should also be given to factors such as the environment (e.g., cold/drafty, average, protected), heat
coverage (sq. ft.) needed, heater centers, the distance behind a person or work station(s), etc. 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 7.
When positioning the heaters, keep in mind the location of combustible materials, lights, sprinkler
heads, overhead doors, storage areas 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 clearances 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 applicable NFPA codes.
Always observe applicable state and local codes.

Heater Mounting
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.
Clearances to combustibles must be maintained when using recessed mount kits (P/N: ELx-FRxx). For
additional information, refer to form # LSH123a - Recessed Mounting Frame Installation Instructions or
contact the factory.
The heater must be level from end to end and may be 0° to 45° on horizontal. Refer to Figures 2.2 and
