VENTING
VENTING OPTION 2
A Listed Type 1 exhaust hood or one that is constructed and installed in accordance with all relevant local and national
Codes� Wood Stone offers eyebrow-type hoods designed specifically for Wood Stone ovens� See specification sheet on
ventilators for Wood Stone ovens� Note that the notch of the hood is even with the front edge of the oven� The hood must
be installed in accordance with the hood manufacturer’s instructions, and with the Standard for Ventilation Control and
Fire Protection of Commercial Cooking Operations,
NFPA 96 and/or the applicable local and national codes� Refer to the
exhaust hood manufacturer’s recommendations for inspection, maintenance and cleaning� Solid fuel burning ovens must
be vented separately from non-solid fuel burning equipment�
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� Due to the possibility of sparks entering the
duct, exhaust systems serving solid fuel equipment MUST not be combined with exhaust systems serving other (non-
solid fuel) equipment� This model is rated as solid fuel equipment and must be vented as such�
VERY IMPORTANT!
WOOD STONE RECOMMENDS THAT YOU CONSULT WITH A QUALIFIED MECHANICAL ENGINEER
AND SUBMIT YOUR VENTING PLANS TO LOCAL CODE AUTHORITIES
BEFORE PROCEEDING WITH INSTALLATION.
NOTE: If your MS-5, MS-6 or MS-7 oven is ordered from Wood Stone without a hood, it will have a round flue adapter
installed to facilitate direct connection to a round duct� If the oven is to be installed under a hood, it MAY be necessary
to remove the round adapter to properly position the hood� This is done by removing the screws that attach the adapter
to the oven� Please contact Wood Stone if you have any questions�

Flue adapter
NOTE: MS-4 ovens come standard with a round 8" O.D. collar
and do not require the flue adapter for a direct connection.
