Certifications

• UL Listed Control Panel
• Meets the Requirements of the Following Standards:
  • NFPA 86 (Standard for Ovens and Furnaces)
  • NFPA 70 (National Electric Code)
  • FM (Factory Mutual)
  • OS

Caution:

• • Ovens processing combustible materials are required to have a fire suppression system per NFPA 86
  • If flammable solvents or vapors are present in an oven, OSHA requires conformance with NFPA 86 Class A Oven requirements.  A powered forced exhauster and other non-standard safety equipment must be added.  See Class A Oven Equipment for Solvent Processing resource page for more information.

Safety Equipment

• Adjustable manual reset excess temperature interlock to turn off heat on malfunction of main temperature controller
• Recirculating blower air flow safety switch to turn off heat on loss of recirculated air flow

• Electric Heat Includes
  • Separate heating element control contactors to turn off heat on malfunction of main control contactors
• Gas heat includes:
• • Modulating burner for 1000 BTU per cubic foot natural gas at 6” water column pressure – propane available.
  • Automatic pre-ignition purge period to clear accumulated gas or fumes
  • Push button electric ignition
  • Microprocessor based electronic flame safeguard protection to continuously monitor flame and close gas valves if flame is not present
  • Powered forced exhauster to provide combustion venting
  • Exhauster air flow safety switch to close gas valves on loss of venting
  • Two pilot valves to guarantee gas flow to pilot can be stopped
  • High and Low gas pressure switches to confirm safe operating pressure range
  • Two main burner safety shut off valves with valve seat position indicator to assure gas flow to main burner can be stopped
  • Proof of closure switch on one main valve to prevent igniting pilot unless main valve is closed
  • Leak test station at each pilot and main burner valve to allow testing for leakage through valve

Controls:
