All installations and services must be performed by qualified service personnel.
3. All wiring sizes must comply with local codes or the National Electrical Code.
To minimize voltage drop to the appliance, the next larger size wire should be
used when long wiring runs, in excess of 100 ft., are employed. Refer to the
wiring diagrams when wiring or servicing.
NOTICE: Proper operation of the heating section of this unit depends upon
correctly connecting the electrical power source. The hot leg, L1, of the
supply circuit must be connected to the black line lead and the neutral leg,
N, to the white line lead in the burner compartment junction box. All
ungrounded circuit conductors must be broken by the disconnecting
switch to prevent the hazard of electrical shock when servicing this
appliance.
In the event a circuit breaker trips or a fuse blows as a result of the operation of
this appliance, investigate the appliance electrical system to determine the
cause. Correct any electrical faults and abnormal conditions before putting the
unit back into operation. Do not put in a larger fuse and do not exceed
maximum fuse size listed on the rating label in order to temporarily “fix”
the problem. The rating label is located on the inside of the burner compartment
cover.
The appliance control system contains a 15 amp. circuit breaker to protect
the heating system control circuitry. The control fuse is located within the
junction box, which is located in the burner compartment. In the event of a main
circuit breaker trip, this may need to be reset as well.
1. Electronic Air Cleaner (EAC) and Humidifier Installation
The fan timer on this unit has designated terminals to control the operation of
an electronic air cleaner and/or humidifier. These terminals provide line
voltage for the control of these accessories, refer to Figure 4.
Connection between EAC and N6 provides a switched 115 vac to power an
electronic fan cleaner.
The same switched 115 vac is available between Fan and N7 and may be
used in conjunction with a humidistat to control a humidifier.
These terminals are energized whenever the blower is active.
