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" x 16" 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.
