To install power to the furnace first remove the cover on the circuit breaker junction box shown Inside you will find the main terminal block See wir ing diagram on page 36 for location of main terminal block and proper power connections In the bottom ofthe box a knockout hole is provided for the incoming wire The minimum recommended circuit is 15 Amp 120 V A C 60 Hz This furnace should be the only appliance on the circuit This furnace should never be powered by the use of an extension cord The recommended high and low voltages are 130 V A C 60 Hz maximum high voltage and 113 V A C 60 Hz minimum low voltage The furnace will continue to operate at voltages as low 105 V A C although it can not be guaranteed that automatic ignition will occur Also there is the possibility of a distribution blower motor overload NOTE If other sources of electrical power are to be used such as a generator for normal opera tion or emergency operation this source should be checked before installation Many generators and inverters may not supply 120V A C 60Hz power stable enough to operate the control board properly Control board damage could occur Checking amp Re cording the Low Draft After the venting is completed the firebox low draft will need to be checked and possibly adjusted After re moving the 3 8 bolt from the draft hole shown in Fig 38 insert the draft meter tube The inner ash door and the hoppe
