Installation
aquastat and wiring
See page 23 for assembly and mounting details. Pay close attention to the jumper positioning inside the A350 and S350
controls. Also note the sensor and its wire length when considering the mounting location. Remember that 212° f. is boiling
temperature and must be avoided. Be sure to incorporate a means for flowing water in the event of an over-heat condition.
Coal can not just stop burning when there is no demand for heat. Never fire a boiler with no water in the system. Serious
consequences will result.
