3.0 INTRODUCTION

DESCRIPTION

Model KLT-12G (12 gallon capacity) gas fired, self-contained, tilting kettle. The kettle has a jacket
of double-wall construction forming a sealed reservoir around the lower two-thirds of the kettle.
The reservoir is charged with distilled water. The kettle is equipped with a “clean lock” to hold
kettle in cooking position or tilted 105 degrees for ease of cleaning. The kettle is also equipped
with automatic ignition, low water cut off and tilt switch, which, when activated, shuts down the
burner.

BASIC FUNCTION

The kettle operates by generating steam in the kettle reservoir. The sequence of operation is as
follows:

1. Operator turns the power switch to the on position and sets the temperature control dial to the
desired setting.

2. The red light comes on indicating the kettle is heating. The green “IGNITION” light comes on
indicating that the ignition and burner are active.

3. Once the kettle reaches the set temperature, the red “TEMPERATURE” light and the green
“IGNITION” light extinguish.

4. All kettles are supplied with sufficient water in the jacket. If for any reason the water level falls
below the required amount to operate the kettle, the burner shuts down and the amber light
comes on. See Adding Water in Service section.

5. The sight glass indicates the water level within the kettle jacket.

6. The relief valve is a safety feature which prevents the internal kettle pressure from exceeding
50 PSI. It should never be tampered with.

4.0 INSTALLATION INSTRUCTIONS

GENERAL

Gas installation to conform to local codes or in absence of local codes to the National Fuel Gas
Code - ANSI Z223.1 - latest edition. In Canada, installation to be according to CAN/CGA- B149.1
(NAT) or CAN/CGA-B149.2 (LP) installation codes as applicable.

1. The appliance and its individual shut-off valve must be disconnected from the gas supply piping

system during any pressure testing of that system at pressures greater than ½ psig (3.45 Kpa).

2. The appliance must be isolated from the gas supply piping system by closing its individual

manual shut off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psig (3.45 Kpa).

The installer must provide electrical grounding according to local codes, or in the absence of local
codes, with the National Electrical Code, ANSI/NFPA 70 - latest edition. In Canada installation
must be according to the C.S.A. C22.2 Canadian Electrical Code.

WARNING

ELECTRICAL GROUNDING INSTRUCTIONS

THIS APPLIANCE IS EQUIPPED WITH A THREE-PRONG (GROUNDING) PLUG FOR YOUR

PROTECTION AGAINST SHOCK HAZARD AND SHOULD BE PLUGGED DIRECTLY INTO A

PROPERLY GROUNDED THREE-PRONG RECEPTACLE. DO NOT CUT OR REMOVE THE

GROUNDING PRONG FROM THIS PLUG. (120 VOLT UNITS ONLY).

The electrical wiring diagram is located inside the right hand console of the appliance.

If applicable, the vent line from the gas appliance pressure regulator shall be installed to the
outdoors in accordance with the local codes or, in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane
Installation Code as applicable.

GAS CONNECTION

1. The Serial and Rating Plate on the unit indicates the type of gas your unit is equipped to burn.

DO NOT connect to any other gas type.

2. A 3/4" NPT line is provided at rear for the connection. The unit is equipped with an internal

pressure regulator which is set at 4" W.C. manifold pressure for Natural Gas and 10" W.C. for
Propane Gas. Use 1/8" pipe tap on the union elbow assembly located in the console for
checking pressure.

An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of
gas required for satisfactory performance. A steady supply pressure, minimum 6" W.C. for natural
gas and minimum 12" 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 problems,
affecting burner operation. Contact you gas company for correct supply line sizes.

Purge the supply line to clean out any dust, dirt or other foreign matter before connecting the line
to the unit. Use pipe joint compound which is suitable for use with L.P. on all threaded
connections.

Test pipe connections thoroughly for gas leaks.

USE SOAPY WATER ONLY FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO

CHECK FOR GAS LEAKS.

ALL THE CONNECTIONS MUST BE CHECKED FOR LEAKS, AFTER THE UNIT HAS BEEN PUT IN

OPERATION.
