Warnings etc

• Bit of Alarm Fatigue with the sheer amount of labels/warnings, sheeesh
  • GRANTED liability, and any sort of fired heater/burner etc IS inherently risky etc, but yeah
• ANYWHO ones worth noting/looking into:
• ”Never use IsoPro fuel containers larger than 8 ounces (227 grams)”
  • This has me thinking it doesn’t have a regulator and/or that would overwhelm the regulator?
• ”In canister fuel mode, stove should not be operated or stored at temperatures below 0f / -18c. In liquid fuel mode with the MSR Arctic Fuel Pump , stove should not be operated or stored at temperatures below -40f / -40c
  • I wonder of this is liability, or of it will not function outside of the limits they mentioned

Operation Guidance

• ”Always start stove wirh fuel canister in upright position prevent a large flare up”
  • Essentially if trying to do liquid feed, you use vapor feed to preheat the Vapor Generator THEN invert the canister (after 30 seconds they say)
  • Then before shutting everything down you flip it BACK once done

Testing

• About 1Min 45 secs to 2 Minutes for a rolling boil fron a coleman brand propane-butane blend
  • Granted borderline at sea level and

  • Does a pretty thorough comparison + teardown
  • Main changes were:
    • from Wire Stand to Cut Flat Stock
    • Thicker Vapor Generator tubing
    • Elastomer rather than Leathet Cup for the Pump
    • Folding Wire+Plastic, rather than near flush knurled knob
    • Fuel Filter at the end of the pump

• A Video by the YouTube Channel “JIUJITSU2000” Titled “Using a Primus Himalaya Omni Fuel Pump with a MSR Whisperlite Universal ( ‘’’~15 Minute Watch’’’ )
  • The Primus Himalaya Omni Fuel pump uses Metal for most components, instead of plastic (hence more durable, yet also more expensive+heavy)
  • Also as “Mosin-007lv” pointed out in the comments, Primus offers larger 1.5L fuel bottles as well
    • A comparison to see which bottle is most Skookum / Overbuilt etc would be nice as well
• A Video by the YouTube Channel “BlackWolfDesigns” Titled “Trangia/MSR Hybrid Stove - Tracy Moorehead” ( ‘’’~5 Minute Watch’’’ )
  • They essentially partially disassemble the stove, remove the legs, then insert it into the Trangia
