GENERAL
Direct steam jacketed kettle(s), pressure vessels of a double wall stainless steel construction
forming a steam chamber (jacket) enveloping the lower two thirds of the kettle bowl surface.
Kettles are mounted on a modular cabinet base housing a gas boiler designed to ASME Code
and approved as a steam heating boiler restricted to operation at pressure not to exceed 15 psi.
The gas boiler may be in a 24 inch cabinet base rated at 140,000 or 200,000 BTU, or 36 inch or
42 inch cabinet base rated at 200,000, 250,000 or 300,000 BTU, operational on Natural or
Propane gas. Boilers may be optional with electronic ignition and CSD-1 controls. All models
are suffixed with either -6 or -10 to indicate the capacity of the kettle in US gallons.
UNPACKING
Immediately after unpacking, check for possible shipping damage. If the appliance is found to
be damaged, save the packaging material and contact the carrier within 15 days of delivery.
Before installing, verify that the gas (natural or propane), the elevation from sea level and the
electrical supply agree with the specification on the data plate. NOTE: If this appliance is being
installed above 2000 feet altitude, contact your authorized service office to assure that the
proper orifice size for your elevation has been installed.
1.0 SERVICE CONNECTIONS
PLUMBING CONNECTIONS
WARNING: Plumbing connections must comply with applicable
sanitary, safety, and plumbing codes.
WATER SUPPLY CONNECTION
The incoming cold water supply connection, at the rear of the appliance cabinet, requires 3/8"
tubing and water pressure of 25 - 50 psi. A manual shut-off valve must be provided convenient
to the appliance; this valve should be open when the boiler is in operation. Incoming hot water
connection (½” (13 mm) ) nominal tube for kettle fill faucet must be installed. See Service
Connections.
FAILURE OR MALFUNCTION OF THIS APPLIANCE DUE TO POOR WATER QUALITY IS
NOT COVERED UNDER WARRANTY. SEE WATER QUALITY STATEMENT, PAGE 4.

BOILER CABINET BASE, GMT-6, GMT-10, GMT-6-6, GMT-10-6, GMT-10-10
DRAIN CONNECTION
The steamer drain (2" IPS) should be piped to a floor drain near the steamer. There should be
no solid drain connection; an “open gap” between the steamer and the floor drain is required.
GAS CONNECTION
1. The data plate on the cabinet door of the boiler indicates the type of gas your unit is
equipped to burn. DO NOT connect to any other gas type.
Keep the appliance area free and clear from combustible substances. Do not obstruct the
flow of combustion and ventilation air.
2. A 3/4" NPT line is provided at the rear for the connection. Each boiler is equipped with an
internal pressure regulator which is set at 3.5" W.C. manifold pressure for natural gas or
10.5" W.C. for LP gas. Use the 1/8" pipe tap on the burner manifold for checking pressure.
An adequate gas supply is necessary. Undersized or low pressure lines will restrict the volume
of gas required for satisfactory performance. A steady supply pressure, between 7" W.C. and
14" W.C. for natural gas and 11" W.C. and 14" W.C. for propane gas is recommended. With all
units operating simultaneously, the manifold pressure on all units should not show any
appreciable drop. Fluctuations of more than 25% on natural gas, and 10% on propane gas, will
create pilot problems and affect burner operating characteristics.
NOTICE: If this equipment is being installed at over 2,000 feet altitude and was
not so specified on order, contact service department. Failure to install with
proper orifice sizing may void the warranty.
Contact your gas company for correct supply line sizes.
Purge the supply line to clean out any dust, dirt, or foreign matter before connecting the line to
the unit.
CAUTION: The pipe thread compound used when installing pipes
must be a type that is resistant to the action of liquified petroleum or
propane gases.
Codes require that a gas shut-off valve be installed in the gas line prior to the steamer. Make
sure the pipes are clean and free of obstructions, dirt, and piping compound.
