1.0 Safety
WARNING
Improper installation, adjustment, alteration, service, or maintenance can cause property
damage, serious injury, or death. Read and understand the installation, operating, and
maintenance instructions thoroughly before installing or servicing this equipment. Only
trained, qualified gas installation and service personnel may install or service this
equipment.
Safety Symbols
Safety is the most important consideration during installation, operation, and maintenance of the infrared
heater. You will see the following symbols and signal words when there is a hazard related to safety or
property damage.
Warning indicates a potentially hazardous situation
WARNING
which, if not avoided, could result in death or injury.
Caution indicates a potentially hazardous situation
CAUTION
NOTICE
which, if not avoided, could result in minor or
moderate injury.
Notice indicates a potentially hazardous situation
which, if not avoided, could result in property
damage.
Applications
This is not an explosion proof heater. Consult your local fire marshal, insurance carrier, and other authorities
for approval of the proposed installation.
Commercial / Industrial (Indoor Use Only)
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.
Residential
This heater is NOT approved for use in any residential application. This includes, but not limited to, attached
garages, living quarters, solariums, etc. Consult the local fire marshal and/or insurance provider if unsure
of your application.
Not For Residential Use.
Installation of an infrared heater system in residential indoor spaces, RV’s,
mobile homes, etc. may result in property damage, asphyxiation, fire, serious
injury, or death.
WARNING

1.0 Safety • Clearance to Combustibles

IHR Series Manual
Clearance to Combustibles
WARNING
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.
CAUTION
Signs shall be posted specifying the maximum permissible stacking height in order to
maintain clearances 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
• Combustion and ventilating air supply
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 infrared surface, or reflector,
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:
• Vehicle parking areas
• 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
The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room
temperature. Building materials with a low heat tolerance (such as plastic, vinyl siding, canvas, tri-ply, etc.)
may be subject to degradation at lower temperatures. It is the installer’s responsibility to assure that adjacent
materials are protected from degradation.
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 gas fired
infrared heaters for approval of the proposed installation.

Gas Connection
WARNING
An approved connector, suitable for the environment of equipment usage, is required.
Visible or excessive swaying, flexing, and vibration of the gas connections must be avoided
to prevent failure. Neither the gas pipe nor the connector shall be placed in the ‘flue
discharge area’. In no case shall the gas supply support the weight of the heater.
To ensure your safety, and comply with the terms of the warranty, all units must be installed in accordance
with these instructions.

Safety Signs and Labels
It is important to provide warnings to alert individuals to potential hazards and safety actions. ANSI Z83.19
and the National Fuel Gas Code require you to post a sign “specifying the maximum permissible stacking
height to maintain the required clearances from the heater to the combustibles” near the heater’s thermostat
or in absence of such thermostats in a conspicuous location. Signs should state the hazards for the
particular application and be legible to the building occupants. Consult the factory or a factory representative
for additional information on signage compliance.
Safety warning labels must be maintained on the
infrared heater. Illustrations of the safety labels,
and their locations, are pictured below.
