5.4 Exhaust Connection
A 3” diameter exhaust port is located on the left side of the oven with a manual butterfly damper. An exhaust
guard is installed to prevent contact with the extremely hot port surface.
A draft diverter, vacuum breaker, exhaust hood, or similar device should be connected between the oven
and the exhaust. This connection prevents “chimney effect” which sucks heat out of the chamber and results
in slow run-up times or poor temperature uniformity. Never use an exhaust stack directly between the oven
and the exhaust.
Vent ductwork should be run to a location outside of the building (as necessary). This should be done in
accordance with all local code regulations. Make sure all connections are secure.
Warning! The exhaust port can become extremely hot. Do not touch. Avoid contact between the
port and flammable materials. Do not vent exhaust against combustible surfaces, areas, or
materials.
