Propane stove: plan the fuel supply before the burners

Quick answer

For outage cooking, pick a propane stove by how you will fuel it. A tabletop two-burner like the Coleman Cascade 222 runs on 1 lb cylinders, and Coleman rates it at up to 1 hour on high per cylinder, so stock several or add Coleman's adaptor hose for a 20 lb tank. A freestanding high-output stove like the Camp Chef Explorer puts 30,000 BTU through each burner for large pots. Either way it is an outdoor appliance only: CPSC and both makers rule out tents, campers, cars and homes.

Two kinds of propane stove, two different jobs

Propane stoves for home preparedness fall into two groups. Tabletop stoves fold into a case and run from a small cylinder. Freestanding stoves stand on their own legs and put out far more heat for big pots and long cooking.

Example	Type	Listed output	Weight	Cooking space
Coleman Cascade 222	Tabletop, 2 burners	22,000 BTU total (11,000 per burner)	13.05 lb	Fits one 12-inch and one 10-inch pan
Camp Chef Explorer 2-burner	Freestanding, removable legs	60,000 BTU total (30,000 per burner)	30.5 lb	14 x 32 inches, 448 sq in

The Explorer's burners are each rated at nearly three times the Cascade's per-burner input (30,000 vs 11,000 BTU). That matters for boiling a large stockpot of water for washing. The Cascade is the easier stove to carry, store and run on small fuel cylinders. Choose the stove that matches the largest pot you actually plan to heat.

Fuel: 1 lb cylinders or a 20 lb tank

Coleman's Cascade 222 manual lists 16 oz disposable propane cylinders as the standard fuel and says never to refill them. Coleman rates the stove at up to 1 hour on high from one cylinder. Count your cooking hours for the days you plan to cover and stock cylinders to match; small bottles suit short outages.

The same manual allows a refillable cylinder of up to 20 lb through the optional Coleman Propane Adaptor With Hose, model 5475. That turns the stove into a much longer-running outage cooker, as long as you follow the connection steps: hand-tighten, leak test with soapy water, and close the cylinder valve when the stove is not in use. Coleman says to keep using the preset regulator that came with the stove and not to adjust it.

Camp Chef sells an RV connection hose for its cooking systems and a natural gas kit. Its FAQ limits the natural gas kit to low-pressure systems on a supply rated at a 7-inch water column (0.25 psi), and says a converted stove cannot go back to propane unless the valves are replaced. Have a qualified gas installer handle any fixed gas connection.

Where you can run it, and where you cannot

Both makers are blunt. The Cascade manual says never use the stove inside a house, camper, tent, vehicle or other unventilated or enclosed area, and adds that it is not for home or recreational vehicle use. Camp Chef's FAQ answers "Can I use indoors?" with a plain no. CPSC reports that people die every year from carbon monoxide produced by camping stoves, heaters and lanterns used inside tents, campers and vehicles.

In a power outage, that rules out the kitchen, the garage and an enclosed porch. Set the stove outdoors on a sturdy, flat surface, away from doors, windows and vents, and keep the Coleman clearances: 12 inches from combustible materials at the sides and 48 inches above. Do not leave it unattended, and keep children and pets away while it is lit.

Know the warning signs. CPSC lists headache, dizziness, weakness, nausea, vomiting, sleepiness and confusion as carbon monoxide symptoms, and notes the risk rises at high altitude. Get to fresh air if anyone feels them.

Store and handle propane safely between uses

The Cascade manual lists the propane rules that apply to any stove of this type:

• Never store propane near heat, flames, pilot lights or direct sunlight, or anywhere above 120°F.
• Propane is heavier than air and collects in low places. If you smell gas, turn the stove off, put out nearby flames, shut off or remove the cylinder and leave the area.
• Never connect or remove a cylinder while the stove is lit or still hot.
• Check every connection with soapy water before cooking. Bubbles mean a leak. Never use a flame to test.
• Never run the stove with a cylinder upside down.

Coleman also points to NFPA 58 and local codes for propane storage. Keep spare cylinders outside the living space.

What to buy for an outage cooking kit

Build the kit around the stove, not just the stove itself:

• The stove, sized to your largest pot.
• Fuel for several days. Either a supply of 1 lb cylinders or a filled 20 lb tank plus the maker's approved adaptor hose.
• A backup way to light it. The Cascade manual says a wet igniter may not spark and to use a match if it fails.
• Battery-backed carbon monoxide alarms inside the home, as a backup if fumes drift in.
• A stable outdoor spot with wind protection. The Cascade has two wind guards and the Explorer a three-sided windscreen.

Run the stove once before you need it. Assemble it, leak test the connections and boil a pot of water so you know the setup works.

What to look for when you buy

Questions people ask

Can I use a propane stove indoors during a power outage?

No. Coleman's manual says never use its stove inside a house, camper, tent or vehicle, Camp Chef says outdoor use only, and CPSC reports deaths from camping stoves used in enclosed spaces. Cook outside, away from openings.

How long does a 1 lb propane cylinder last on a camp stove?

It depends on the stove and flame setting. Coleman rates the two-burner Cascade 222 at up to 1 hour on high per 16 oz cylinder and the one-burner Cascade 18 at up to 2.5 hours.

Can I run a camp stove from a 20 lb propane tank?

Some stoves allow it with the maker's adaptor. Coleman's Cascade 222 manual permits refillable cylinders up to 20 lb through its Propane Adaptor With Hose, model 5475. Leak test the connections and close the tank valve after use.

Can I refill 1 lb propane cylinders?

Not the disposable ones. Coleman's manual says never refill disposable cylinders. Use a refillable cylinder and an approved adaptor instead.
