VENTING
VERY IMPORTANT! WOOD STONE RECOMMENDS THAT YOU SUBMIT VENTING PLANS TO LOCAL CODE
AUTHORITIES BEFORE PROCEEDING WITH INSTALLATION.
FIRE DECK VENTING
Fire Deck model numbers containing a “-CL” must be vented in accordance with codes concerning solid fuel appliances (NFPA
96)� Due to the dangers of creosote buildup and sparks entering the duct, these models must be vented separately from all
other kitchen equipment and in a manner acceptable to the authority having jurisdiction� The Wood Stone customer support staff
is available to answer any questions concerning installation and venting of the oven� Call 1�800�988�8103 for assistance and
technical support�
Solid fuel exhaust contains creosote and other substances that accumulate in ducting, creating a risk of fire� The rate of
accumulation will vary� Frequent, regularly scheduled, thorough flue cleaning is the best way to minimize the risk of flue fires�
VENTILATION SYSTEM: CREOSOTE AND FLY ASH
When solid fuel is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form
creosote� The creosote vapors condense in the relatively cool oven flue of a slow-burning fire� As a result, creosote residue
accumulates in the duct� When ignited, this creosote makes an extremely hot fire� The duct serving this oven should be inspected
at least twice a month during the first two months of operation to establish the rate of creosote (and fly ash—see below) buildup
and the necessary cleaning schedule� If creosote or soot has accumulated, it should be removed to reduce the risk of a flue fire�
The interior floor and dome of the oven do not require creosote or soot removal� The oven flue and exhaust system will require
inspection and cleaning� The exhaust system should be inspected and cleaned per the manufacturer’s and or local code official's
recommendations�
While coal burning generally produces very little creosote, it does produce fly ash which will accumulate in the duct system� If
allowed to accumulate the fly ash can block the air flow through the duct� It can also harden over time making removal much
more difficult� Because of the acidic nature of the fly ash and the combustion products produced from coal burning, the entire
duct system must be cleaned and inspected on a regular basis to ensure safe operation of the ventilation system�
WOOD STONE RECOMMENDS THAT YOU SUBMIT YOUR VENTING PLANS TO THE AUTHORITY
HAVING JURISDICTION BEFORE PROCEEDING WITH INSTALLATION OF ANY GAS AND/OR
SOLID FUEL BURNING APPLIANCE.
