The Codes Our Panels Are Designed To Exceed


Guide to Planning School Science Facilities 2nd Edition 2007 

    “Manual shut-off switches should be located so that the teacher can easily access them and shut off the electricity, gas or water in different zones when not needed for science activities”

    “Emergency shut-off controls for electrical or gas service should be highly visible, clearly labeled, and available to the teacher, but not easily accessible to the students. They are normally located near the teacher’s station and not far from the hallway exit, but not immediately adjacent to the hall door. The placement should be such so that the students are not able to hit the switch as they exit the class each period causing repetitive problems.”

    “The clearly labeled emergency gas shut-off valve should be activated by pushing a highly visible button, with a keyed reset mechanism to turn the gas supply back on when the emergency is over. The keyed reset feature can also be used by the teacher to shut off the gas when it is not needed in lieu of the control valve mentioned above. Models that have red shut off buttons recessed into a metal frame minimize the possibility of an inadvertent shutoff. All emergency controls in the laboratory / classroom should be in a location that is readily accessible by the teacher, but not easily reached by students.”

    Designing Facilities for the Middle School (6-8) 

    “If central gas is used, it should be located at the perimeter, near the sinks. The room should have a button-activated emergency shut-off valve.”

    “Place emergency shut-off controls for electrical service, and gas near the teacher’s station, not far from the door, and not too easily accessible to students.”

    Designing Facilities for the High School (9-12)

    “When gas is provided by a central system, an emergency shut-off valve, activated by pushing a highly visible visible button, will be needed. A central control valve can enable the teacher to shut off the gas in the room when not in use. Emergency shut-off controls for electrical service and gas should be near the teacher’s station, not far from the door, and not easily accessible to students.”


    Review of NFPA Codes and Standards as they apply to to the Merlin Range for Commercial Kitchen Protection systems

      Under the NFPA (54) Code & (2002), ventilating hoods and exhaust systems shall be permitted to vent gas-fired equipment installed in commercial applications. However, certain requirements must be met, including:
      • These same requirements apply for systems with standing or electronic pilot ignitions.
      • A valve shall be located on the main gas line feeding the appliances served by the gas hood and shall stop the flow of gas to the appliances upon loss of draft. No by-pass of the gas solenoid valve is allowed.
      • Where automatically operated gas utilization equipment is vented through a ventilating hood or exhaust system equipped with a damper or with a power means of exhaust, provisions shall be made to allow the flow of gas to the main burners only when the damper is open to a position to properly vent the equipment and
      when the power means of exhaust is in operation.
      • The gas valve must be controlled by a draft proving switch measuring draft within the hood. The gas valve is allowed to be open only when the fan is operational or the damper is 100% open.
      • The gas valve shall be equipped with a manual reset (integral or otherwise). The valve must be manually reset only when the lock-out condition is corrected. The reset cannot be automatic.
