Each unit must be connected to a dedicated electrical circuit. NO OTHER DEVICES SHOULD
BE ON THE SAME ELECTRICAL CIRCUIT AS THE HEATER.
A double-pole switch must be installed on the electrical supply line in an easily accessible
location to quickly and safely disconnect electrical service. DO NOT attach the switch to sheet
metal enclosures of the unit.
After placing the unit in service, the ignition safety shutoff device must be tested. If an external
electrical power source is used, the installed unit must be electrically bonded to ground in
accordance with the requirements of the authority having jurisdiction. In the absence of such
requirements, the installation shall conform to National Electrical Code (NEC), ANSI/NFPA 70
and/or the Canadian Electrical Code (CEC) Part I, CSA C22.1 Electrical Code.
For electrical power wiring diagrams, see the AERCO Innovation and RECON Electrical Power
Wiring Guide, GF-5060.

2.12 FIELD CONTROL WIRING
Each unit is fully wired from the factory with an internal operating control system. No field control
wiring is required for normal operation. However, the C-More control system used with all
RECON Heaters does allow for some control and monitoring features. Wiring connections for
these features are made in the Input/Output (I/O) Box. The I/O Box is located on the upper-left
portion of the unit front panel (Figure 2-13) behind the removable front panel. To access the I/O
Box terminal strips shown in Figure 2-14, loosen the four cover screws and remove the cover.
All field wiring is installed from the rear of the panel by routing the wires through one of the four
bushings provided.
Refer to the wiring diagram provided on the cover of the I/O Box, or Figure 2-14, when making
all wiring connections.
