Dwarf Wood Stove

This diagram and descriptions of the function of each Dwarf Wood Stove component should help you more fully understand the function and assembly of your stove. Many of these components contribute directly to the performance and heating efficiency of the Dwarf wood stoves. Read more about the keys to wood stove efficiency in our free ebook.

Door with spring handle

The Dwarf wood stove door is cast iron painted with high-temperature stove paint. It has a large viewing window and comes with a cool-to-the-touch spring handle. A fiberglass rope gasket is used to ensure an air-tight seal.

Air wash intake

A sliding valve controls the air intake above the door of the stove. This intake directs the air down across the glass of the door to help with combustion to keep the glass clean of creosote. The rate of burn can be controlled using a combination of this air intake valve as well as the primary and secondary air intake valves on the bottom of the stove body.

Coal Bar

The coal bar helps prevent coals from falling out of the stove when you open the door. It is removable for easy access to clean the ashes from the fire grate.

Air control slides

These levers control the air-tight primary and secondary air intakes on the bottom of the stove. The one on the left allows primary air into the stove underneath the fire grate and the one on the right allows air to enter the top of the firebox to facilitate secondary combustion. (Note: the LITE model stove uses a single lever to control both air supplies.)  Read more in this article about how to control your burn rate.  


4” cast iron stove legs come included with every Dwarf wood stove. Optional accessories include tall cast iron legs and wood storage stands

Fire grate support

The fire grate supports are bolted to the bottom of either side of the stove body. They support the fire grate at the bottom of the fire box, and the fire bricks on either side of the firebox. Two bolts can be tightened to secure the fire brick in place.  (Note: the LITE model stove uses lightweight refractory fiber panels instead of firebrick, so firebrick support bolts are not included in that model).

Stove body

The Dwarf stove body is made of thick 3/16″ – 5/16th steel plate. (Note the LITE model uses thinner steel to save on weight.)

Direct air intake box (optional)

The direct air intake box is sold separately. It attaches to the bottom of the stove, forming an airtight seal around the primary and secondary air intake openings. The 3” flange allows fresh air to be piped into the stove from outside. Doing so increases the stove’s efficiency at heating your space. Supplying outside air keeps your warm air in the room instead of sending it up the chimney to be replaced by cold drafts entering your space through cracks around windows and doors. If your space is very airtight, the direct air intake might be necessary to ensure the stove gets enough fresh air to function. (Note: the 3kW LITE model cannot be used with the direct air intake box)

Flue flange and cover plate

The cast iron flue flange provides a stable mounting surface for connection to your flue system. It can be installed on either the top or rear of the stove for flexibility in your installation. (Note, the LITE model only offers a top exit option.) The cover plate is then installed on the unused outlet. Single wall stovepipe should be sealed to the flue flange with gasket cement. Optionally, screws can be used for added stability; this is more important in a mobile structure.


The steel baffle facilitates secondary combustion in the firebox. It slows the flue gases down and improves the mixing of secondary air with combustion products, giving gases extra time to fully combust before leaving the stove and allowing time for more heat transfer into your space. The baffle can be a bit… baffling to install/remove your first time or two. See tutorial here.


Firebricks insulate the firebox, helping it achieve higher temperatures and more complete combustion by directing more of the heat back into the fire. They also shield the sides of the stove from the direct heat of the fire, which helps improve the longevity of your Dwarf stove.

Fire grate and riddling grate

The cast iron fire grate elevates the fuel from the bottom of the stove. This allows air to reach the fire from underneath for a more complete burn and also gives access to clean out the ashes below while the fire is still burning. The riddling grate (not included in the LITE model) is a round section of the fire grate that can turn freely with a rod connected to a knob on the front of the stove. Using this knob to move the grate back and forth helps shake ashes down to the bottom of the stove for removal.

Rear air plate

In the back of the stove is a wall with air holes penetrating it. The secondary air enters through these holes, feeding the top of the fire fresh oxygen, helping to facilitate complete combustion.

Ash pan

Included with your stove is an ash pan that fits into the space under the fire grate. The ash pan can be used with the help of the included ash pan tool to remove ashes during operation.
