Gillette Generators SPS-100, SPH-120, SPS-120, SPV-160 Installation Manual

If you’re staring at a crate with a Gillette Generators SPS-100, SPH-120, SPS-120, or SPV-160 and the only thing between you and a working standby system is a pile of wires and gas fittings, this is the paper you need. Not a generic PDF scraped off some forum – the actual Gillette Generators SPS-100, SPH-120, SPS-120, SPV-160 Installation Manual from the manufacturer. Thirty pages of factory installation data that tell you where every conduit goes, what pressure the fuel regulator needs, and how to wire the control panel without letting the magic smoke out.

Fuel System Setup: Natural Gas and LPG

Pages 12-15 cover the gaseous dry fuel system for both Natural Gas and Liquid Propane Gas. The manual splits them into separate sections because the orifices and regulator adjustments are different. Don’t assume you can swap NG for LPG without re-reading the conversion procedure on pages 19-20. The fuel line sizing chart, pipe length restrictions, and manifold pressure specs are all there – use them. I’ve seen generators that wouldn’t start because someone ran NG through a line meant for LPG. That’s a call-back you don’t want.

What Are the Critical Safety Warnings Before Installation?

Pages 3-6 aren’t lawyer filler. They spell out danger points: never install indoors, keep clear of air intake, use listed gas shutoff valves, and follow NFPA 70. The manual states this generator does not comply with emergency power as defined by NEC – that means you can’t run life-support loads on it without additional gear. If you ignore the warnings on page 3, you’re risking a fire or carbon monoxide event. Read them twice before you uncrate the unit.

30 Pages of Factory Installation Data

Twenty-nine pages of tightly packed instructions plus a maintenance record sheet on page 27. The table of contents alone will save you time: from un-packing and inspection (pages 6-7) to dimensional prints for each model (pages 23-25). The service schedule on page 26 lists oil changes, valve adjustments, and battery checks at specific hour intervals. No guesswork – just the intervals Gillette tested.

Wire the Electrician’s Wiring Installation Correctly

Pages 15-18 walk you through battery selection, interior access, and the electrician’s wiring installation. The 8-point diagnostic panel is highlighted on page 18 – that’s your go-to for troubleshooting a no-start condition. The manual shows the control system connections for the automatic transfer switch and the DC control wiring. Use stranded wire of the gauge listed; solid wire will crack in the vibration. If you’re unfamiliar with control logic, check the wiring diagram on page 11 – “Know your Gillette Automatic Control System”.

Dimensional Prints: Models SPS-100, SPH-120, SPS-120, and SPV-160

Pages 23-24 give you the footprint for the three smaller units. Page 25 covers the SPV-160, which is physically larger. These prints include mounting bolt locations, center of gravity, and clearance requirements for the enclosure doors. Don’t pour a concrete pad until you verify these dimensions – I’ve seen pads poured six inches too short because someone eyeballed it. Use the print, measure twice, pour once.

One more thing about aftermarket documentation: I don’t trust it. This is the OEM Gillette manual, not a third-party reprint. The wiring colors match what’s actually in the junction box, and the torque values for terminal lugs came from Gillette’s engineering team. That matters when a loose connection causes voltage drop under load.

FAQ

Does this manual include torque specs for the mounting bolts?

Not explicitly – installation manuals often omit fastener torque because the bolts are supplied with the unit. However, the manual does specify tightening sequences for electrical connections and fuel fittings. For mounting bolts, use standard torque for the grade listed on the dimensional print.

Can I use this manual to convert fuel from NG to LPG?

Yes. Pages 19-20 cover the field conversion procedure step by step.
