Mountain Series Installation and Operation Manual
oVen VentinG
Allow sufficient opening
between any facade and
the inside edge of the
front of the hood to allow
for filter removal and
hood cleaning. Any front
facade wall should not
be built any higher than
the top of the oven to
allow for access to the
filter.
It is never appropriate to use “B vent” in any part of an exhaust system connected to a Wood Stone oven. 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 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.
Note that the notch of the hood is even with the front edge of the oven. The hood should be installed in accordance
with the hood manufacturer's instructions, and with NFPA 96 and/or the applicable local and national codes.

3. Exhaust from Wood Stone gas-fired ovens (RFG models) can be vented using one of the previously mentioned
methods OR can be combined with exhaust from other equipment, assuming the common duct meets the
construction requirements listed in #1. If the Wood Stone oven is installed using the direct connect method, and
is going to be tied into a common duct that is connected to any hoods; the system must be engineered so that
the duct pressure at the oven flue collar is -0.1 inches W.C. (-0.14 inches W.C. for solid fuel models). Failure to
properly engineer the venting system will severely compromise oven performance and reliability. Tying a direct
connected Wood Stone oven into a common duct may not be a feasible solution for many installations. In these
cases the oven must either be vented separately, or vented using a Type 1 hood.
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.
