Protect your kitchen personnel from scalding and other serious injury by providing training programs to ac-
quaint all equipment operators with the correct and safe methods of operation.
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.
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.
Keep this manual for daily reference.
INTRODUCTION:
Market Forge, in the interest of both cost and efciency 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 efciency
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 identication, 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 GAS BOILER:
An explanation of how the control system operates on automatic gas boilers follows:
After the boiler is lled with water to the proper level and the fuel switch is turned ON, the main gas valve will be
activated allowing gas to ow to the main burners that will be ignited by the Spark Pilot. When the boiler builds to
its set pressure, the pressure switch opens. This will open the circuit to the gas valve that will stop the ow of gas
to the main burners. 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 FILL/ON-OFF switch to the OFF
position.
