US Customers: Below is our
Fire Deck Venting Recommendations Page. You can
choose either the Fire Deck 6045 & 8645 or the Fire Deck 9660 & 9690.
6045 &
8645 Fire Decks: Fire Deck model numbers containing a W should be vented in accordance with codes concerning solid fuel appliances (NFPA 96). Due to the dangers of creosote buildup and of sparks entering the duct, these models should be vented separately from all other kitchen equipment or in such a manner as is 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 with respect to flue gas temperature, wood type and moisture content. Frequent, regularly scheduled, thorough flue cleaning is the best way to minimize the risk of flue fires. CREOSOTE - AND THE NEED FOR ITS REMOVAL When wood 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 rate of creosote buildup and necessary cleaning schedule. If creosote or soot has accumulated, it should be removed to reduce the risk of a flue fire. 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. 9660 & 9690 Fire Decks: The Wood Stone Fire Decks 9660 & 9690 must be vented through a 12" ID flue collar located on the top of the oven, above the doorway. Fire Deck model numbers containing a W should be vented in accordance with codes concerning solid fuel appliances (NFPA 96). Due to the dangers of creosote buildup and of sparks entering the duct, these models should be vented separately from all other kitchen equipment or in such a manner as is 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. The following options are the manufacturer's recommendations for venting the Fire Deck 9660 & 9690 ovens: 1. A Listed building heating appliance chimney, which is also a listed grease duct connected directly to the oven flue collar and provided with a 450 degree F (300 degree F for 9690) power ventilator listed for restaurant appliance exhaust. A single wall chimney/duct connector may be used to connect the oven to a listed building heating appliance chimney also listed as a grease duct. The chimney/duct connector should be a minimum of 0.044" stainless steel or 16 ga. mild steel (0.055") and must maintain a minimum of 18" clearance to combustibles. A static pressure of -0.1 inches water column (-0.14 for wood burning models) is necessary at the oven flue collar to ensure that gas temperatures do not exceed 450 degrees Fahrenheit at the fan inlet. The CFM required to attain this static pressure will depend on the configuration of your particular installation but will probably be between 800 and 1000 CFM. Wood Stone provides a port in the flue collar of the oven for insertion of a Magnehelic gauge so the installer can monitor the draft to ensure proper operation of the venting system. 2. A Listed exhaust hood or one that is constructed and installed in accordance with all relevant local and/or national codes and connected to a 450 degree F power ventilator listed for restaurant exhaust. Exhaust hoods for wood burning models must be constructed and installed in accordance with NFPA 96. 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. International Customers Note: Wood Stone ovens should be vented in accordance with pertinent national, regional and local codes concerning such appliances; check venting plans with the authority having jurisdiction before proceeding with installation. |
