The IRI gas train is an optional gas train configuration which is required in some areas for code
compliance or for insurance purposes. The IRI gas train is factory pre-piped and wired. See
Appendix F, Drawing AP-A-830 for details.
2.8 AC ELECTRICAL POWER WIRING
The AERCO Benchmark 1.5 Electrical Power Wiring Guide, GF-4060, must be consulted prior
to connecting any AC power wiring to the unit. External AC power connections are made to the
unit inside the Power Box on the front panel of the unit. Remove the front door of the unit to
access the Power Box mounted directly above the Control Box. Loosen the four Power Box
cover screws and remove cover to access the AC terminal connections inside the Power Box
(Figure 2-7).
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.
