The large one. Twin burners at 10,000 BTU/h each (11,790 BTU/h on the European CE measurement), with individual micro-control valves so you can run a slow simmer on one side and a full boil on the other. Push-button piezo ignition and a built-in carrying handle.

At 21.4 x 12.9 x 3.8 inches it is about three inches wider than the Selkirk 460+, which is the whole point — more room between the burners for two real pans. Welded, nickel-chrome-plated 4 mm steel pot supports take an 8 inch and a 10 inch pot side by side, the support lifts out and the burner surround is stainless for cleanup. Steel with a powder-coated exterior.

In the box: regulator, 2 burner heads, pot support, upper windscreen, side windscreens, igniter, handle and 2 flame adjusters. Wraparound windscreens fold out of the way for larger pots on calm days.

Fuel: propane

GSI's spec sheet lists the fuel for this stove as propane, and a regulator comes in the box — the normal arrangement for a standard 1 lb propane bottle. GSI's own page for this model does not print the words “1 lb,” so we are not going to put that in their mouth as a specification. If you want it confirmed in writing before you order, ask us and we will get it.

If you camp in one spot for days at a time, our 5 ft Propane Adapter Hose lets a Type-1 propane appliance run off a refillable 5–20 lb tank instead of a stack of disposable bottles.

Safety — please read before you buy

This stove is for outdoor use only. Never use it in a tent, a vestibule, a vehicle, a house, or any enclosed area. It produces carbon monoxide, a gas with no odor and no color, and improper use can cause suffocation, poisoning or death. Never block airflow to the burner or to the stove's venting. It can ignite nearby materials and flammable liquids or vapors, so keep the stove and the fuel away from other heat sources. Never let children operate it, and keep them at least 10 feet away from the cooking area.

Care

Hand wash with warm, soapy water and dry thoroughly; avoid abrasive cleaners. Let the stove cool completely first, and check that the burner ports are clear and the fuel fitting is clean and undamaged before every trip.

Which GSI stove takes which fuel

GSI's camp stoves split into three fuel families that do not interchange, and their own listings never lay this out in one place. Ours does:

• Threaded isobutane canister — the screw-on 110 g and 230 g canisters. Glacier Camp Stove, Glacier Canister-Top Stove, Glacier Remote Stove.
• Butane cartridge — Pinnacle Radiant, Selkirk 270.
• Propane — Pinnacle Pro 2-Burner, Selkirk 460+, Selkirk 540+.

Two adapters bridge between them: the Butane-Isobutane Adapter lets a butane cartridge feed an isobutane stove, and the 5 ft Propane Adapter Hose lets a Type-1 propane appliance run off a refillable 5–20 lb tank instead of disposable bottles. Both are listed separately.
