Certain materials or objects, when stored under the heater, will be subjected to radiant heat and
could be seriously damaged. Observe the Minimum Clearances to Combustibles listed in the manual and on the heater
at all times.
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 the openings
•
Combustion and ventilating air supply
•
Vehicles parking areas
•
Vehicles with lifts or cranes
•
Storage areas with stacked materials
•
Lights
•
Sprinkler heads
•
Overhead doors and tracks
•
Dirty, contaminated environment
This heater is approved for both INDOOR and OUTDOOR installation. Both installation options have different clearances
to combustibles as described below. These must be observed.
INDOOR clearances to combustibles are defined as a surface temperature of 90°F above ambient temperature.
OUTDOOR clearances to combustibles are defined as a surface temperature of 117°F above ambient temperature.
OUTDOOR Spaces are defined as a shelter no more inclusive than:
a)
with walls on all sides, but with no overhead cover.
b)
within a partial enclosure which includes an overhead cover and no more than two side walls. These side
walls may be parallel, as in a breezeway, or at right angles to each other.
c)
Within a partial enclosure which includes an overhead cover and three side walls, as long as 30 percent or
more of the horizontal periphery of the enclosure is permanently open.
For the purposes of clearances to combustibles and ventilation all applications not classified as
outdoors according to the definitions above shall comply with the requirements for indoor installations.
Minimum clearances shall be measured from the outer surfaces of the heater or heat shield if installed, as shown in
the diagrams for the different installation positions.
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.
Sprinkler systems containing propylene glycol or other flammable substances are not to be used in conjunction with
this heater without careful consideration for and avoidance of potential fire or explosion hazards. For further information
consult the authority having jurisdiction. Always observe applicable state and local codes.
Always maintain minimum clearances and post signs where needed. This heater is supplied with a
wall mounted sign shown below. It is the installers responsibility to ensure that the sign is completed with the correct
clearance to combustible distances for the installation and that the sign is posted in a location where it is easily
accessed.
