Installation
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 loca-
tion. Remember that 212° f. is boiling temperature and must be avoided. Be sure to incorporate a means for
owing water in the event of an over-heat condition. Coal can not just stop burning when there is no demand
for heat. Never re a boiler with no water in the system. Serious consequences will result.
