NOTE
It is the responsibility of the customer to source and purchase the
appropriate gas regulator as described above. However, AERCO
offers for sale an appropriate regulator, which may be ordered at
the time of unit purchase or separately. Contact AERCO for more
information.
2.11 AC ELECTRICAL POWER WIRING
The AERCO Innovation and RECON Electrical Power Wiring Guide, GF-5060, must be
consulted prior to connecting any AC power wiring to the unit – contact the factory for a copy of
this guide. External AC power connections are made to the unit inside the Power Box on the
front of the unit. Remove the Lower-Front Enclosure and the Access Panel to access the Power
Box (see Appendix E – Parts List Drawings for diagrams). The Power Box is mounted on the
right side of the unit directly below the Control Box. Loosen the four Power Box cover screws
and remove the cover to access the AC terminal connections inside the Power Box (Figure 2-
11).
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.
