6. Fuel Fill Model 1 (Catalog 23, p63) • Spill Containers • Model 1 In Ground Spill Container • Drains oil spilled from delivery disconnect into storage tank • Designed to handle driveway traffic • Removable bellows for easy fuel testing without pavement excavation.

7. Fuel Fill Model 2 (Catalog 23, p61) • Model 2 In Wall Spill Container • For indoor storage tanks with fill lines to building walls • Standard models from simple box to integrated digital level display and overfill alarming • We can customize many things:A bronze Model 2 was recently installed at Radio City Music Hall to contribute to the building’s décor.

8. In Wall Spill • We required that all components in the alarm station be of explosion proof construction including the alarm horn, alarm light, silencing push-button and digital remote readout (if required). • Explosion proof components are required for safety and to prevent the ignition of the fuel oil vapors generated from the sun heating the spill container.

14. Anti-Syphon Valves • Patented by Preferred Utilities. • UL Labeled & Listed Catalog 23, p74

15. Anti-Syphon Valve Manifold

16. Anti-Syphon Valve • In addition to requiring a UL listed valve we now require a Bronze valve rather than a cast iron • We state the ability of bronze not to crack or fail in a fire condition. • We have also explained the importance of the valve. • It is too important to substitute. • We want to get the sale when we get the system or not. We are the only ones that make a ½ & ¾ version. Catalog 23 Page 74

17. Anti-Syphon Valves • Used where fuel leaks will result in fuel being syphoned into areas which can cause a dangerous and costly situation • UL Labeled and listed • For No. 2 through No. 6 Oils • 5’, 10’, 15’ or 20” Head Selection • Installed at highest point in piping

18. Fire Safety Shut-off Valves • Lever Gate Valve • Fully mechanical • Emergency fuel line shut-off is mandated by many codes • Fusible links open at 165F • for pipe ranges 3/4" - 3" • Fusomatic Valve • Replaceable fusible element • Fusible links open at 165F, May be manually opened/closed • for pipes 3/4" or 1" Model 110 with alarm switch (Catalog 23, p72) Fusomatic Valve (Catalog 23, p71)

19. Type 110 Fire Valve

20. Foot Valves • Ensures maintenance of pump prime by preventing oil backflow into the tank when pumps are off • Single Poppet • 1/2” to 3” Size • Double Poppet • Double the protection • 1-1/2” or 2” Sizes • Foot Valve Extractor Fitting • Easy Removal and Inspection of Foot Valve

25. Fuel Components • Tank Selector Valves • Replaces confusing array of hand valves • Simple lever operation transfers both supply & return lines from one tank to the other • Designed with no “blind spots” where flow could be blocked to or from the tanks • Threaded or flanged connections available Threaded Connection (Catalog 23, p81)

26. Back Pressure Regulating Valves • Used in a flow loop to maintain proper pressure for burners. • Type BQ for flow rates up to 390gal/hour • Standard Ranges of 26-75psi or 76-150psi • 1/2” Size • Type V for higher flow rates • Standard Range of 30-150psi • 1” Size

27. Strainers • Duplex • No flow interruption for routine cleaning • 90° handle movement switches baskets • Handle blocks inadvertent opening of active side • Sizes from 3/4" - 6" • Simplex • Special yoke design for quick cleaning • Large basket • Sizes from 1/2" - 2" Duplex Oil Strainer (Catalog 23, p43)

28. Pump Sets Components • Multiple pumps share common suction and discharge piping • Most common is duplex set • two 100% pumps, one for backup • control system can monitor flow, start lag pump • Triplex pump sets for large plants • three 50% pumps allow for one spare • two 100% “winter pumps” - one 50% “summer pump”
