PANT-LEG VENT CONNECTIONS (Figs. 7, 8)
IMPORTANT: Gas heat machines must be provided with a means to exhaust the flue gases to the
exterior of the building. Pant-Leg duct connectors (Fig. 7) alone DO NOT provide ventilation for the
gas flue at the rear of the machine. A mini vent hood (Fig. 8) must be used or a canopy type hood may
be used.
Moist air escapes from each end of the conveyor type dishwasher. The exhaust requirements
recommended are a maximum of 200 CFM at the entrance end of the dishwasher and a maximum of
400 CFM at the discharge end. Optional vent hoods or extended hoods may be provided at each end
of the machine. Sufficient make-up air must be provided so the exhaust flow results in a positive building
pressure in the room in which the unit is located (more outside air than exhaust air). Hoods are provided
with 4" x16" vent connectors with vent dampers which allow adjustment during installation. Typical
construction is for 'Pant-Leg' hood connections to the 4" x 16" vent connectors (Fig. 5). Vent stacks
must be watertight and fit inside the vent connector openings.
