2.11.1 Electrical Power Requirements
AERCO Innovation Heater built for the International market require the following input voltage:
•
120 VAC, single-phase, 50/60 Hz @ 20A
•
220 VAC, single-phase, 50/60 Hz @ 20A
NOTE:
All electrical conduit and hardware must be installed so that it does not interfere with the
removal of any unit covers, inhibit service/maintenance, or prevent access between the unit
and walls or another unit.
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 water heater 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.
