Wood Stone appliances should be vented in
accordance with NFPA 96, UL 103 and/or all
pertinent national, regional and local codes
concerning such appliances; check venting
plans with the authority having jurisdiction
before proceeding with installation.
All of the combustion products and cooking vapors from the WS-BH-4343 and WS-BH-
4355 models pass through the 10-inch diameter flue collar (8" for the WS-BH-3030-
RFG), located atop the appliance. The appliance can be connected to a power ventilated
chimney, or placed under a hood. The WS-BH-4343-RFG-W, WS-BH-4355-RFG-W models
may burn up to 3 lbs. of wood per hour and must be vented as a solid fuel burning piece
of equipment.
VENTING
The following are the manufacturer’s recommendations for venting the Wood Stone Bistro. It is never
appropriate to use “B vent” in any part of an exhaust system connected to a Wood Stone appliance. All
ducting material must be manufactured to the specifications of a grease duct.
Due to the possibility of
sparks entering the duct, exhaust systems serving SOLID FUEL equipment SHOULD NOT be combined
with exhaust systems serving other (non-solid fuel) cooking equipment.
There are two options:
1.
A Listed building heating appliance chimney, also listed as a grease duct connected directly to the
appliance flue collar and provided with a power ventilator listed for restaurant appliance exhaust and
rated for operation at a minimum of 300 degrees F. Use a stack or curb mounted fan.
Wood Stone does
not recommend the use of an in-line fan.
A single wall chimney/duct connector (of unspecified length)
may be used to connect the appliance to a listed building heating appliance chimney also rated as a
grease duct. Any single wall ducting 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 is necessary at the appliance flue collar to ensure proper
flue temperatures at the fan. The airflow required to attain this static pressure will depend on the
configuration of your particular installation but will probably be between 300 and 500 CFM.
The exhaust
fan must be turned on any time the appliance is running.
See instructions for optional interlocking of
the appliance to the fan at the end of this manual.
