TO THE KITCHEN MANAGER:
1. Read this manual carefully and in its entirety. Contact Market Forge Ind., Inc. for clarification if necessary.
2. Protect your kitchen personnel from scalding and other serious injury by providing training programs to acquaint all
equipment operators with the correct and safe methods of operation.
3. Operators must be made aware of the consequences of misuse. Steam producing equipment, no matter who the
manufacturer, is inherently dangerous when misused. The possibility of serious scalding always exists, the careless
and/or untrained operator will be injured.
4. This equipment must be maintained according to the guidelines in this manual (see "maintenance"). Lack of maintenance
will lead to a potentially hazardous condition and possible liability. Operators should report any equipment malfunction
immediately and steps must be taken to correct the problem before further use of the equipment is allowed.
5. Keep this manual for daily reference.
INTRODUCTION:
Market Forge, in the interest of both cost and efficiency has designed these steam boilers with the latest automatic
controls in order to make it easier for the operator to use and maintain this equipment. Standard components are
utilized on all models unless variances in size or capacity dictate a divergence from this policy for more efficiency of
operation. This parts and service manual is written and illustrated to cover all steam boiler equipment that uses gas
as a source of fuel other than those which have been custom designed under special order.
HOW TO USE THIS MANUAL:
The pictures of components are aids to the identification, disassembly and assembly of parts. The parts listing
provides information necessary for the ordering of replacement parts (proper part names and part numbers). When
requesting parts or service; always furnish the model and serial number of your complete unit, this will indicate to
Market Forge Service Personnel the type of boiler that you have. This information can be found on the nameplate
attached to the boiler frame.
THEORY OF OPERATION FOR ELECTRIC BOILER:
An explanation of how the control system operates on automatic electric boilers follows:
With the boiler filled with water to the proper level and the fuel switch is turned ON, the contactors will pull in and
permit the completion of the electric circuit to the heating element. When the boiler builds to its set pressure, the
pressure switch opens. This will open the circuit to the coil in the contactor, which in turn will drop put the contacts in
the contactor and shut off the electricity. As the pressure in the boiler drops the pressure control switch will again
complete the circuit and build the boiler back to its set pressure. To stop all steam generation place the fuel switch to
the OFF position.
