Learning to Control Your Small Wood Stove
Operating a wood stove is a skill you develop over time. Each stove has its quirks, and how it behaves will depend on many factors: your flue configuration, elevation, weather conditions, and fuel choice. The key is to spend time getting to know your stove, and to practice how the controls affect your fire. With patience and a little trial and error, you’ll learn how to start fires that light quickly, burn clean, and keep your space warm.
In this guide, we’ll cover:
- How the air controls on your stove work
- Proven methods for starting a fire
- Tips for managing fuel and maintaining a hot coal bed
- How to adjust your stove’s burn rate and temperature
- What clean burning looks like (and what to avoid)
Understanding Your Stove’s Air Controls
The Dwarf Wood Stoves have three types of air supplies. See the Dwarf Manual to identify which knobs control which air intakes.
- Primary air: Feeds the bottom of the fire and burns through the coal bed.
- Secondary air: Enters at the top of the firebox to help burn gases and smoke completely.
- Tertiary or “air wash”: Directs air across the glass to keep it clean while also supporting combustion.
Some less efficient stoves may also use a flue damper to reduce draft. On modern, efficient stoves, the goal is usually to rely on secondary air for most of the burn. That keeps the fire cleaner and your chimney clearer.
Wood fires naturally burn from the top down, so once your fire is established, you’ll want to restrict the primary air and feed more oxygen from the top. If you’re burning coal, it’s the opposite—coal burns from the bottom up and needs stronger airflow through the grate so you'll allow the majority of the air in with the primary air and restrict the secondary.
How to Start a Fire
Every good fire starts with four essentials:
- Tinder: Easy-to-light material such as newsprint or fire starters
- Kindling: Small, dry sticks about pencil thickness
- Fuel: Larger, properly cured hardwood logs in varying sizes
- Flame: Matches or a lighter
When you light a fire, you’re working toward two goals: warming the flue quickly to get the draft moving, and building a hot bed of coals. Beginners often focus too much on flames, but coals are what make a fire self-sustaining.
Try various methods for starting fires to find what works best for you and your stove. We’ve found a few methods that tend to work very well for small stoves. Start with all of your air controls open 100%.
Log Cabin Method
Stack kindling in alternating layers, crisscrossing like a log cabin. Place a fire starter on top, light it, and close the door most of the way. Once burning, add more kindling, then small fuel pieces.
“Good News” Method
Crumple sheets of newspaper to line the bottom of the firebox. Build your kindling stack on top in alternating layers. Light the paper in several spots and close the door most of the way. Once caught, add more kindling, then fuel.
As the fire builds, progresively add larger logs. Aim for a thick, glowing coal bed before adjusting the controls to settle into steady heat. You should see little or no visible smoke coming from your chimney unless you’ve just added a new piece of wood. Thick plumes of dark smoke indicate an inefficient burn, and call for an adjustment to your technique.
Your priority for managing an efficient fire is to maintain your coal bed. If your coal bed burns out before your fuel is reduced to coals to replace it, then your logs are too large for the fire you’re burning. Use smaller logs to burn a hot and efficient fire, and keep a healthy coal bed going at the bottom of your fire box.
Managing Heat and Efficiency
Unlike a furnace, your stove won’t adjust itself automatically—you control the fire by balancing air supply and fuel.
Adjusting the Air
- Keep primary air open while starting the fire, then close it down once you have a solid coal bed.
- Rely on secondary air to maintain clean, efficient burning.
- Keep the tertiary air at least halfway open to keep your glass clear.
- Make adjustments gradually. Closing air controls too fast can cause the fire to smolder, producing creosote and smoke.
Adjusting the Fuel
- Small, dry pieces burn hotter and faster.
- Larger logs burn slower and cooler.
- For more heat, feed smaller pieces more frequently.
- For a slower, steady fire, add larger pieces and turn the air controls down.
Your main goal is to maintain a strong coal bed. If your coals burn out before your fuel is reduced to coals to replace them, your logs are too large for the size of fire you’re running.
Checking Your Burn
The easiest way to tell if you’re burning cleanly is to step outside and look at your chimney.
- Clean burn: Little to no visible smoke once the stove is hot.
- Inefficient burn: Thick, dark smoke billowing from the chimney.
Some smoke is normal right after adding a log, but it should clear up quickly once the wood catches. If smoke stays heavy, adjust your technique or fuel.
Keep Practicing
Two people can run the same stove with the same fuel and get very different results. That’s why practice matters. The more time you spend starting fires and learning how your stove responds, the better you’ll get at clean, efficient burning.

I have found that I get the best burn with the least effort by building an upside down fire in my Cubic Mini. An upside down fire is built by stacking perpendicular layers of logs into the stove with the largest logs on the bottom and ending with kindling on the top. I like to use hardwoood kindling and a piece of fat lighter or waxy cardboard on top. You light it from the top leaving the door open as it takes off and then closing the door once the second layer catches. This fire requires very little poking and since a full firebox of wood sits beneath the kindling, you don’t have to keep adding wood to build a coal bed- just let it burn down. This fire makes less smoke since flames don’t have to travel up through cooler logs and achieves a clean burn faster than traditional fire building methods. Give it a try, I bet you will convert!

Thanks for the tip! How long of a burn time have you been able to get out of your Cubic Mini using the upside-down fire method? Do you have the Cub or the Grizzly?
We do the same with our Dwarf stoves, and it’s how we get the longest possible burn time overnight. Nick has reported as long as a 10 hour burn in our Dwarf 5kW using the upside-down fire method. The airtight firebox and three separate air controls on the Dwarf make it ideal for controlling the burn rate for long burns, since you can shut down the primary air entirely, set the air wash to 50%, and feather in the secondary air to hit the sweet spot.
I’ve tried doing an upside-down fire in my Salamander Hobbit (a 4kW stove), but because the primary and secondary air are controlled by the same valve, it’s very difficult to get the fire not to consume the entire pile all at once. I’m lucky to get 4 hours. Folks with our similar sized Dwarf 4kW with the three separate air controls seem to have much more success with upside-down fires, reporting 8 hour burn times with hardwood fuel and air settings dialed in.
