Static inlet gas pressure should not exceed 14" W.C. for either
natural or propane gas. The minimum value is for purpose of
input adjustment.
The gas valve (Fig. 3) is provided with a pressure tap to
measure the gas pressure downstream, which is also the
manifold pressure. Gas supply piping must have a sediment
trap (supplied by others) installed ahead of the dishwasher's
gas control (Fig. 3).
NOTE: DO NOT use Teflon tape on gas line pipe threads. For
gas line pipe connections, use L
OCTITE 565, Hobart part 546292
or a flexible sealant suitable for use with Natural and Propane
Gases.
The appliance and its gas connections must be leak tested
before placing the appliance in operation. Use soapy water for
leak test. DO NOT use open flame. The installation must
conform with local codes, or in the absence of local codes, with
the National Fuel Gas Code, ANSI Z223.1 (latest edition).
Copies may be obtained from American Gas Association, Inc.,
1515 Wilson Boulevard, Arlington, VA 22209.
The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1
/2 psig (3.45kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or
less than
1
/2 psig (3.45kPa).
Dissipate test pressure from the gas supply line before re-connecting the appliance and its manual
shutoff valve to the gas supply line. Caution: Failure to follow this procedure may damage the gas
valve.
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.
