15 System V olt age - That nominal voltage value assigned to a circuit or system for the purpose of designating its volt age class. Nameplate V olt age - That voltage assigned to a piece of equipment for the purpose of designating its voltage class and for the purpose of defining the minimum and maximum voltage at which the equipment will operate.
16 Check tension frequently during the first 24 hours of opera- tion. Subsequent retensioning should fall between the mini- mum and maximum force. T o determine the deflection dis- tance from the normal position, use a straightedge or stretch a cord from sheave to sheave to use as a reference line.

19 The pressure regulator on LP gas models is adjusted for 10.0" w .c. manifold pressure and is intended to prevent over-firing only . Do not attempt adjustment of the built-in pressure regu- lator unless the supply pressure is at least 7.0" w .
20 A UTOMATIC R ESET H IGH L IMIT C ONTROL (LS) Located in the burner compartment on the heat exchanger , its sensing element project s through the blower section bulk- head and senses the temperature at the rear of the furnace. It will cycle the furnace off if the temperature exceeds 100°F plus maximum rise.
21 Open Thermal Protection Device If the primary limit switch opens, the gas valve is immediately deenergized, the induced draft and air circulating blowers are energized. The induced draf t and air circulator blowers remain energized until the limit switch recloses.
22 for the purpose of airflow balancing, but once the balance has been achieved, fixed sheaves maintain alignment and minimize vibration more effectively .
