VENTING
THIS MODEL MUST BE VENTED AS A SOLID FUEL APPLIANCE
The following are the manufacturer’s recommendations for venting the Wood Stone MS (Mountain Series) W-IR ovens�
It is never appropriate to use “B vent” in any part of an exhaust system connected to a Wood Stone oven� All duct
material must be manufactured to the specifications of a grease duct� This is a wood/gas combination oven and must
be vented as a solid fuel piece of equipment� Due to the possibility of sparks entering the system, exhaust systems
serving solid fuel equipment must be vented separately from other non-solid fuel equipment� 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� Typically, we recommend monthly cleaning for all solid fuel ovens� Submit
your venting plans to your local authorities before proceeding with your installation, as there may be additional
requirements in your area�
There are two venting options:
VENTING OPTION 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 restaurant appliance exhaust�
The power ventilator should be rated for a minimum of 450 °F� Wood Stone does not recommend the use of an in-line
fan� A field built grease duct, constructed and installed to the specifications of a grease duct as detailed in NFPA 96 or
the International Mechanical Code, may also be used�
A static pressure of -0�14 inches water column is necessary at the oven flue collar to ensure that flue gas
temperatures do not exceed 450 °F at the fan inlet� This measurement may be taken by inserting the probe of the
magnahelic gauge through the oven doorway, upwards to the oven flue collar�
NOTE:
Double door ovens (models
ending in “-DD”), have two flue collars, both must be connected and a static pressure of -0�14 inches must be
maintained at each collar� See table below for CFM required to attain the specified static pressure�
NOTE:
Solid fuel
burning ovens must be vented separately from non-solid fuel burning equipment�

of the authority having jurisdiction�
