Dayton High-Intensity Heaters
Description
Dayton high-intensity heaters become highly efficient generators
of infrared radiation by heating a ceramic refractory material to
incandescence. The principal operation is to pass a gas-air mixture
through a perforated ceramic refractory, and ignite it on the refractory
surface. This causes the ceramic material to be heated to approximately
1780°F and generate large amounts of infrared radiation that may be
directed anywhere heat is desired. Infrared radiation heats people and
objects it strikes and not the intervening air. Included is a direct spark
ignition system, manifold pressure tap, porous ceramic grids, a polished
aluminum reflector and a chain set for hanging the heater. Typical
applications are loading docks, warehouses, service garages, factories,
aircraft hangars, etc.
WARNING
Improper installation, adjustment,
alteration, service or maintenance can
cause property damage, injury or death.
Read and understand the installation,
operating and maintenance instructions thoroughly
before installing or servicing this equipment.
This heater must be installed and serviced by trained
gas installation and service personnel only. Failure to
comply could result in personal injury, asphyxiation,
death, fire and/or property damage.
WARNING
Not for residential use!
This heater is not approved in any
quarters, attached garages, etc. Installation in
residential indoor spaces may result in property
damage, serious injury or death.
residential application. This includes
(but is not limited to) the home, living
the required clearances from the heater to the
combustibles. Signs must either be posted adjacent
to the heater thermostats or in the absence of such
thermostats, in a conspicuous location.
For Your Safety
If you smell gas:
• Do not try to light any appliance.
• Do not touch any electrical switch.
• Do not use any phone in your building.
• Immediately call your gas supplier from a
neighbor’s phone.
• Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier,
call the fire department.
Keep these instructions for future reference.
WARNING
In locations used for the storage of
combustible materials, signs must be
posted to specify the maximum
permissible stacking height to maintain

Safety is the most important consideration during
installation, operation and maintenance of the infra-red
heater. You will see the following symbols and signal
words when there is a hazard related to safety or
property damage.
WARNING
Warning indicates a potentially hazardous situation
which, if not avoided, could result in death or injury.
CAUTION
Caution indicates a potentially hazardous situation
which, if not avoided, could result in minor or moderate
injury.
This is not an explosion proof heater. Consult your local
fire marshall, insurance carrier and other authorities for
approval of the proposed installation.
Commercial / Industrial
Infra-red 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.

in serious injury and death, explosion,
poisonous fumes, toxic gases,
asphyxiation. Connect gas lines in
accordance to national, state, provincial
and local codes.
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.
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 infra-red surface, or reflector,
and the combustible item. Considerations must also be
made for moving objects around the infra-red heater.
The following is a partial list of items to maintain
clearances from:
Signs shall be posted specifying the
maximum permissible stacking height in
order to maintain clearances to
combustibles.
CAUTION
Combustible Items Include:
Failure to comply with the published
clearances to combustibles could result in
personal injury, death and/or property
damage.
• Wood
• Paper
• Fabric
• Chemicals
• Wall or roof insulation
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
• Vehicle parking areas
• Vehicles with lifts or cranes
• Storage areas with stacked materials
• Lights
• Sprinkler heads
• Overhead doors and tracks
• Dirty, contaminated environment
Moving Objects Include:
• Overhead doors
• Vehicles on lifts
• Cranes
• Hoists
• Car wash equipment
When installing the infra-red 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 marshall, fire insurance carrier or
other qualified authorities on the installation of gas fired
infra-red heaters for approval of the proposed
installation.

Maintain Clearances to Combu stibles to Prevent the Risk of Fire.
Clearances to combustibles must be maintained 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 thermostats or in the absence of such
thermostats in a conspicuous location. Clearances are provided on
the heater’s safety labels and in the heater’s Installation & Ope ration
Manual. Refer to applicable ANSI or NFPA-54 Standards or local codes
for further information. Post this tag adjacent to the heater’s
thermostat or controls before operating the heater.
