3 INSTALLATION
3-1 LOCATION
3-1.1 Ovens shall be located to protect them from damage by external heat, vibration
and mechanical hazards.
3-1.2 Ovens shall be located to minimize exposure to power equipment, process
equipment and sprinkler risers. Unrelated stock and combustible materials shall
be maintained at a fire-safe distance but not less than 2-1/2 feet from an oven or
ductwork.
3-1.3 Ovens shall be located to minimize exposure to people from the possibility of injury
from fire, explosion, asphyxiation, and hazardous materials and shall not obstruct
personnel travel to exit ways.
3-1.4 Ovens shall be located to prevent an ignition source to flammable coating dip
tanks, spray booths, storage and mixing rooms for flammable liquids, or exposure
to flammable vapor or combustible dust clouds. Ovens should not be located in
hazardous (classified) locations unless they are designed to comply with the
applicable requirements of NFPA 70 ANational Electrical Code@ (see Appendix A).
3-1.5 Equipment shall be protected from corrosive external processes and environments,
including fumes or materials from adjacent processes or equipment that produces
corrosive conditions when introduced into the oven environment.
3-1.6 The oven is not intended for outdoor installation and must be sheltered from
weather. Unheated shelters may result in non-uniform temperatures or insufficient
heat to attain maximum operating temperature. Condensation may also occur
which would be detrimental to the steel structure and electrical components.
3-1.7 Suitable portable fire extinguishers should be available and operators trained in
their use. All such fire protection equipment should be inspected periodically in
accordance with appropriate standards. Reference NFPA 10 AStandard for
Portable Fire Extinguishers@ (see Appendix A).
3-2 BUILDING CONSIDERATIONS
3-2.1 When selecting the location for an oven, consideration must be given to the
possibility of fire, building damage and personal injury. Hazards to be considered
include overheating of material in the oven and escape of exhaust into the work
place.
3-2.2 Ovens shall be located so that the building structural members are not affected
adversely by the maximum anticipated temperature or by the additional loading
caused by the oven and load.
3-2.3 Ovens should be placed on noncombustible surfaces.
3-2.4 Level the oven using shims, if necessary. Where mounting holes are provided,
anchor the oven securely. Shims should be permanently mounted to the oven
after installation. Mounting holes are provided on leg stands; anchor the stands
securely.
3-3 CLEARANCES
3-3.1 Ovens shall be located with adequate space above and on all sides to allow
inspection and maintenance. Provisions also shall be included for the installation
of automatic sprinklers, if applicable.
