VENTING REQUIREMENTS — WITH GAS TANK HEAT
The Hobart AM14F / AM14T / AM14TC dishwasher equipped for gas tank heat is not provided with a
flue collar and is not intended to have the flue directly connected to a ventilation system. However, the
products of combustion must be vented to the outside air. The most common method of venting is a
vent hood over the entire dishwasher (Fig. 4). Refer to Rate of Exhaust Flow Calculations on the next
page for calculations of the proper vent rate for your hood. Another method is a small vent hood (Fig. 5)
positioned about five inches above the flue exit at the rear of the dishwasher and connected to existing
ductwork. In either case, an electrical interlock must be provided to allow the flow of gas to the
dishwasher burner ONLY when the exhaust system is energized. For additional information, refer to
the National Fuel Gas Code, ANSI Z223.1, NFPA 54.
• IMPORTANT: Make sure the installation meets the local code for your area.
