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.
CONNECTING YOUR WOOD-FIRED COOKSTOVE
You can install your Deva 100 to a prefabricated metal chimney or a masonry chimney.
CONNECTING TO A PREFABRICATED METAL CHIMNEY
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,
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.
