2.6  Safety — NFPA Explosion Relief

Explosion relief required at 15:1 ratio: 6,667.9 cu.ft. volume / 444.5 sq.ft. relief area required.

RELIEF AREA PROVIDED

(2) Man Access Doors: 30.7 sq. ft.

(2) Part Openings: 66.6 sq. ft.

(1 lot) Ceiling Panels: 460.6 sq. ft.

(1) Heater Box Access Door: 4.8 sq. ft.

Total Relief Available: 562.7 sq. ft.

Do not place, block, or install objects on, in front of, or next to any explosion relief panels, ceiling panels, man doors, or product doors. The oven roof is designed to provide the necessary explosion relief area; the exhaust fan must be located so that no more than two roof panels are prevented from lifting in the event of a deflagration within the oven. Ceiling panels and explosion-relief side walls require a minimum of 3'-0" clearance, and doors must be able to swing fully open.

2.7  Other Operating Notes

Adjustable ductwork slides should be half-open at start-up.

Minimum 6" clearance from part to ductwork recommended for optimum cure performance and to prevent powder blow-off.

Oven is not designed to support any additional loads.

Exhaust fan location is approximate; final placement by customer/installer.

Maximum gas train (safety shutoff valve) to burner pipe run: 15 ft.

Pre-ignition purge interval: 5.3 minutes.

Exhaust blower rated for 18.7 gallons of solvent per hour at maximum operating temperature of 500°F.
