FMS-118 Remote Stove with Preheat Tube

What does the preheat tube do?

The preheat tube warms fuel before it reaches the burner.

This allows liquid fuel from an inverted canister to vaporize before combustion, providing another fuel-delivery option when colder temperatures reduce normal canister pressure.

Can I use the fuel canister upside down?

Yes, but always start with the canister upright.

Allow the burner and preheat tube to warm thoroughly before slowly inverting the canister. If the flame becomes unusually large, unstable, or begins pulsing, return the canister upright and reduce the valve.

Do I need to invert the canister during normal use?

No. Upright vapor-feed operation is recommended in normal temperatures and generally provides easier flame adjustment.

Use inverted liquid-feed mode only after warm-up and when colder conditions make it necessary.

How is the FMS-118 different from Blade 2?

Both are remote-canister stoves with preheat tubes and inverted-canister capability.

The FMS-118 uses stainless-steel supports and weighs 5.1 oz (146 g).
Blade 2 uses more titanium components and weighs 4.8 oz (135 g), making it the lighter option for weight-focused trips.

What cookware works best?

Use compact or medium backpacking cookware whose base contacts all three pot supports evenly.

The broad burner works well with wider solo and two-person pots, but oversized or heavily loaded cookware may still create an unstable setup.
