Hobart AM14C ML-32615 Dishwasher User Manual


 
8
The dishwasher must be installed so that the flow of combustion and ventilation air will not be
obstructed. Adequate clearances for air openings into the combustion chamber must be provided.
Make sure there is an adequate supply of make-up air in the room to allow for combustion of the gas
at the burner(s).
Keep the appliance area free and clear from all combustible substances. Do not obstruct the flow of
combustion and ventilation air. The dishwasher must have a minimum clearance from combustible
construction of 1 inch from the flue at the rear and 0 inches at the sides. A clearance of 40 inches must
be provided at the front of the dishwasher for servicing and proper operation.
The burner is ignited automatically by solid state electronic circuitry; there is no pilot light. Gas flow
is regulated by the temperature control circuit.
VENTING REQUIREMENTS — WITH GAS TANK HEAT
The Hobart AM14 / AM14C 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.
