Install the stove as close as practical to the 
chimney, while maintaining all proper 
clearances. Install stovepipe that is as short and 
as straight as possible. Horizontal runs
of
stovepipe should always rise away from the 
stove a minimum of 1/4" per foot (21mm/m). 
 
Long runs of stovepipe to increase heat 
dispersal are not recommended. Using longer 
lengths of stovepipe or more connecting elbows 
than necessary increase the chances of draft 
resistance and the accumulation of creosote 
buildup. 
 
In general, you do not need to install a stovepipe 
damper with the Deva. Some installations, 
however, could benefit from a stovepipe 
damper, such as a tall chimney which can create 
a higher than normal draft. In such cases, a 
damper can help regulate the draft. The Deva 
requires a draft between 0.06" w.c. and 0.1" w.c. 
For drafts above 0.1" w.c, install a stovepipe 
damper. Locate your local HearthStone dealer to 
purchase a draft gauge to measure the draft of 
your chimney and flue system. 
 
Remember, the NFPA has recommended, 
minimum clearances for chimney connectors to 
combustibles such as walls and ceilings.

When connecting the Deva 100 to a 
prefabricated metal chimney, you must follow, 
precisely, the manufacturer's installation 
instructions. Use only Type HT (2100 deg. F), 
prefabricated metal chimneys listed per UL 103 
or ULC S629 standards. 
 
 
▌ WARNING: 
DO NOT CONNECT THE STOVE TO A 
CHIMNEY FLUE SERVING ANOTHER 
APPLIANCE. 
Make sure the size of the chimney’s flue is 
appropriate for the Deva 100. The Deva 100 
requires a 6" (152 mm) inside diameter flue for 
new installations. A 6” diameter flue provides 
adequate draft and performance. You can use 
an 8" (203 mm) diameter existing flue with a 
reducer. An oversized flue contributes to 
creosote accumulation. (In this case, bigger is 
NOT better.) 
When purchasing a prefabricated chimney to 
install with your stove, be sure to also purchase 
from the same manufacturer, the wall pass-
through (or ceiling support package), "T" 
section package, fire-stops (when needed), 
insulation shield, roof flashing, chimney cap, 
and any other needed accessories. Follow the 
manufacturer’s instructions when installing the 
chimney and accessories. In addition, be sure to 
maintain all manufacturers’ recommendations 
for the proper clearances to the chimney. 
 
There are two ways to install a prefabricated 
metal chimney: 
 
•
An interior installation where the chimney 
passes inside the residence through the 
ceiling and roof.
 
• 
An exterior installation where the chimney 
passes through the wall behind the stove 
then up the outside of the residence.
