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 GAS BOILER:

An explanation of how the control system operates on automatic gas boilers follows:

After the boiler is filled with water to the proper level and the fuel switch is turned ON, the main gas valve will be activated allowing gas to flow 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 flow 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.
