VENTING REQUIREMENTS — WITH GAS TANK HEAT

Hobart model AM15, AM15F or AM15T dishwashers equipped for gas tank heat are not provided with

a ue collar and are not intended to have the ue 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. 12). 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. 13) positioned about ve inches above the ue exit at the rear of the dishwasher and connected

to existing ductwork. In either case, an electrical interlock must be installed to allow the ow 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.
