Dayton Patio Heaters
Description
Dayton high-intensity patio 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 stainless
steel housing and a preset mounting bracket for mounting the heater.
Typical applications are restaurant patios, 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. Inspect the
heater annually. Failure to comply could result in
personal injury, asphyxiation, death, fire and/or
property damage.
WARNING
Not for indoor residential use.
This heater is not approved for use in
garages, solarium, living quarters, etc. Installation in
residential indoor spaces may result in property
damage, asphyxiation, serious injury or death.

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.
Warning Symbols
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.
NOTICE
Applications
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 outdoor
restaurant patios, 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.
Outdoor Residential
This heater may only be used in outdoor residential
applications and is NOT approved for use in any indoor
residential application. This includes, but not limited to,
attached garages, living quarters, solarium, etc. Consult
the local fire marshal and/or insurance provider if unsure
of your application.
Notice indicates a potentially hazardous situation which,
if not avoided, could result in property damage.
residential indoor spaces may result in property
damage, serious injury or death. In residential
applications this heater may only be used outdoors.

WARNING
Improperly connected gas lines may result
in serious injury or 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 the heater.
Failure to comply with the published
clearances to combustibles could result in
personal injury, death and/or property
damage.
Hazards Include:
For maximum safety the building must be evaluated for
hazards before installing the heater system. Examples
include, but 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
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:
Combustible items include :
• Wood
• Paper
• Fabric
• Chemicals
• Wall or roof insulation
Moving objects include:
• Overhead doors
• Vehicle 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 minimum clearance to combustibles label
(F/N: LLPCL002) found 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.
Signs shall be posted specifying the
maximum permissible stacking height in
order to maintain clearances to
combustibles.

WARNING
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.
Design
To ensure a safe, properly designed heating system, a
layout should be developed for the correct placement of
the infra-red heater(s). Aside from safety factors such as
clearance to combustibles (see Chart 1.1 on page 5),
you should take into consideration:
• The environment (e.g., is it cold/drafty, average,
protected)?
Note: The effective infra-red surface temperature
of a person or object may be diminished with
• What is the area of heat coverage (e.g., sq. ft.) needed
wind above 5 mph, wind barriers may be required.
(Chart 2.1, Figure 2.2)?
CAUTION
This heater cannot be used in a building with a roof that
is not insulated or where condensation problems can
occur.
This installation manual, along with national, state,
provincial and local codes, address these issues. It is
critical that you read, understand and follow all
guidelines and instructions. Always inspect and evaluate
the mounting conditions, space for exhaust, gas supply
and wiring.
IMPORTANT: Fire sprinkler heads must be located at
an appropriate distance from the heater. This distance
may exceed the published clearance to combustibles.
Certain applications will require the use of high
temperature sprinkler heads or relocation of the heaters.
• Is the heater being used in a social gathering area, or
work station(s)?
• The mounting height of the heater (Chart 2.1, Figure 2.3).
• The type of mounting to be used.
• Physical space needed for the heater (Figure 2.1).
• Gas supply and connections.
• Combustion, ventilating air supply and exhaust path.
• Electricity and wiring to the heater.
Potentially flammable substances, such as Propylene
Glycol or antifreeze solutions, are not to be used in
conjunction with this heater.
For further information consult NFPA 13. Always
observe applicable state and local codes.
