A fireman's switch is not required, and usually not even "recommended". It is usually mentioned in the instructions only in the event you want to hook it up. The switch is actually a remote tied to a timer that turns the heater off ~20 minutes before the pump to save the gas and use up the remaining heat energy in the exchanger as the pump finishes it's cycle.

Locate the pressure switch within the safety circuit and jump the two wires that are connected to it. Be sure the power is off when doing so. Then you can power up the unit and it should fire assuming all the remaining safety circuit switches are closed. DO NOT RUN this for more than a few moments as you can damage the heat exchanger rather quickly operating the burners without water flowing thru the heater.
