PRIMARY AIR CONTROL: This feature is 
located on the lower portion of the ash door of 
the stove. The primary air control allows you to 
regulate the amount of air entering the firebox. 
Generally speaking, the more air allowed into 
the firebox, the faster and hotter the rate of burn; 
conversely, less air creates a slower burn. Push 
the lever to the left to open the primary air 
control; push the lever to the right of the stove 
to close the primary air control.
ASH PAN: The ash pan is located under the 
firebox door. The ash pan collects burned ash 
from a fire and allows you to conveniently 
remove the ash from your wood stove. The ash 
pan is easy to remove. Sift the ashes across the 
grate and into the ash pan, then rotate the ash 
door handle to the 9:00 o’clock and pull to open. 
Remove the ash pan by grabbing the handle and 
sliding it out carefully. After you have disposed 
of the ashes, push the ash pan all the way into 
the stove and close the ash door by turning the 
handle to the 6 o’clock position. 
Remove ashes when the stove is cold. If the ash 
pan is warm, use protective fireplace gloves. 
Exercise extreme caution when handling, 
storing or disposing of ashes.

IREWOOD
Your Deva 100 cookstove is designed to only 
burn firewood-also known as cordwood.  
 
▌ CAUTION: 
DO NOT USE CHEMICALS OR 
FLAMMABLE FLUIDS SUCH AS 
GASOLINE, NAPHTHA, KEROSENE, 
CHARCOAL LIGHTER FLUID OR 
ENGINE OIL TO START A FIRE. DO 
NOT USE CHARCOAL, PELLETS, 
COAL, ARTIFICIAL LOGS OR ANY 
OTHER MATERIALS AS FUEL; THEY 
ARE NOT SAFE. DO NOT BURN 
GARBAGE. 
The quality of your firewood affects heat output, 
duration of burn and performance of your stove. 
Softwoods generally burn hotter and faster, 
while hardwoods burn longer and produce more 
coals. Density and moisture content are two 
critical factors to consider when purchasing 
wood for your stove. 
 
The following is a list of wood species and their 
relative BTU (British Thermal Unit) content. 
The higher the BTU the longer the burn. 
Firewood with higher BTUs is generally 
considered more ideal for a wood stove.
 
 
HIGH: Apple, Black Birch, Hickory, Locust, 
White Oak, Black Beech, Mesquite 
 
MEDIUM HIGH: White Ash, Beech, Yellow 
Birch, Sugar Maple, Red Oak 
 
MEDIUM LOW: Black Ash, White Birch, Grey 
Birch, Elm, Norway Pine, Pitch Pine, Black 
Cherry, Soft Maple, Tamarack 
 
LOW: White Pine, White Cedar, Balsam Fir, 
Spruce, Aspen, Basswood, Butternut, Hemlock 
 
Moisture content also plays a key role in the 
performance of your stove. Wood freshly cut 
from a living tree (green wood) contains a great 
deal of moisture. As you might expect, green 
wood has difficulty burning and should be 
seasoned before using it in your cookstove. To 
properly season green wood, it should be split, 
stacked and allowed to air dry for a period of 
one year. 
 
Stack the firewood on skids or blocks to keep it 
off the ground, cover only the top of the stack. 
Plastic or tarps that cover the sides of the 
woodpile trap moisture and
prevent the wood
from drying. As for stacking, an old Vermonter 
said, "The spaces between the logs should be 
large enough for a mouse to get through, but not 
for the cat that's chasing it." 
 
Firewood should not be stored within the stove's 
specified clearances to combustible materials.
