All ducting material must be manufactured to the specifications ofa grease duct and a listed building heating appliance chimney. This is a wood/gas combination ovenOVEN VENTINGand must be vented as a solid-fuel piece of equipment. Due to the possibility of sparks entering thesystem, exhaust sytems serving solid fuel equipment must be vented separately from other non-solidfuel equipment. Submit your venting plans to your local authorities before proceeding with yourinstallation, as there may be additional requirements in your area.There are three options:1. Direct connection.A listed building heating appliance chimney, also listed as a grease duct as described in NFPA 96,connected directly to the oven flue collar and provided with a power ventilator listed for restaurantappliance exhaust. The power ventilator should be rated for a minimum of 450 degrees F. WoodStone does not recommend the use of an in-line fan. A single wall chimney/duct connector may beused to connect the oven to a listed building heating appliance chimney also listed as a greaseduct. The chimney /duct connector should be a minimum .044 inch stainless steel or 16 ga. mildsteel (0.055 inch) and must maintain a minimum of 18 inches to combustibles.A static pressure of negative 0.14 inches water column is necessary at the oven flue collar to ensurethat flue gas temperatures do not exceed 450 degrees Fahrenheit at the fan inlet. The CFM required to attainthis static pressure will depend on the configuration of your particular installation but will probably be between500 and 700 CFM. Wood Stone provides a port in the flue collar of the oven for insertion of a magnehelicgauge so the installer can monitor the draft to ensure proper operation of the venting system. NOTE:Double door ovens (Models ending in DD), have two flue collars, both must be connected and astatic pressure of negative 0.14 inches must be maintained at each collar.When using a direct connection as described above, the duct must be attached to the ovenflue collar with a full perimeter weld.Install venting system in accordance with the duct manufacturer's instructionsand in accordance with all local codes. All field built components should bebuilt to the applicable codes and standards and are subject to the approval ofthe authority having jurisdiction.OVEN VENTINGContinued on next page.2.
