HOBART CLCS66e ML Series Dishwasher
Pant-Leg Vent Connections
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. 10) alone DO NOT provide ventilation for the gas
flue at the rear of the machine. Amini-vent hood (Fig. 11) must be used or a canopy
type hood may be used (Fig. 9).

and 400 CFM (CLe)/175 CFM (CLeR) 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. 10). Vent stacks must be watertight and fit inside the
vent connector openings.
If using the 'Pant-Leg' duct, a mini-vent hood (Fig. 11) must be used to vent the
flue gases on machines using gas heat. The mini-vent hood must be positioned
a minimum of 18" above the flue exit at the rear of the dishwasher and connected
to existing duct work. The volume of flue exhaust in the mini-vent hood should not
exceed 200 CFM.
In either case, if a powered means of exhaust is used, an electrical interlock
must be provided to allow the flow of gas to the dishwasher burner only when
the exhaust system is in operation.
For more information, refer to the National Fuel Gas Code, ANSI Z223.1, NFPA54.
In all cases, local codes will prevail.
