A CAUTION: A bonding lug is located below the
junction box. Failure to ground the heater electrically
could affect the heater's electronics. A Bonding Wire
must be installed as per NEC requirements to safeguard
persons and property.
NOTE: See "Time Clock/Fireman's Switch" on page
38 for further instructions if using a time clock/
fireman's switch.
The Electronic Ignition Device automatically lights the
burner upon a call-for-heat. The heater is supplied with a
dual-voltage transformer for 120 VAC or 240 VAC input
power hookup. Factory default configuration is 240 VAC.
When using 120VAC, wire the transformer per Figure 29
and change the blower jumper per Figure 30.
When operating on 120 VAC power, units draw
approximately 1.6 amps. When operating on 240 VAC
power, units draw approximately 1.2 amps.
