Commercial / Industrial (Indoors & Outdoors)

Infrared heaters are designed and certified for use in industrial and commercial buildings such as
warehouses, manufacturing plants, aircraft hangars and vehicle maintenance shops. For maximum safety,
the building must be evaluated for potential hazards before installing the heater system. A critical safety
factor to consider before installation is the clearance to combustibles.

Clearance to Combustibles

Placement of explosive objects, flammable objects, liquids and vapors close to the heater
may result in explosion, fire, property damage, serious injury or death. Do not store, or use,
explosive objects, liquids and vapor 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.

Signs shall be posted specifying the maximum permissible stacking height in order to
maintain clearances to combustibles.

WARNING

!

CAUTION

1.0 Safety • Clearance to Combustibles

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

A critical safety factor to consider before installation is the clearances to combustibles. Clearance to
combustibles is defined 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:

• Vehicles with lifts or cranes

• Storage areas with stacked materials

• Lights

• Sprinkler heads

• Overhead doors and tracks

• Dirty, contaminated environment

Combustible Items Include: Moving Objects Include:

• Wood • Overhead doors

• Paper • Vehicles on lifts

• Fabric • Cranes

• Chemicals • Hoists

• Wall or roof insulation • Car wash equipment

When installing the infrared heater system, the minimum clearances to combustibles must be maintained.
These distances are shown in Chart 1.1 and on the heater. If you are unsure of the potential hazards,
consult your local fire marshal, fire insurance carrier or other qualified authorities on the installation of
infrared heaters for approval of the proposed installation.

SW Series Manual

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
specific details.
