WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
Important: All phases of this installation must comply with
NATIONAL, STATE, and LOCAL CODES. In
absence of local codes, the installation must
conform with American National Standard-
Z223.1a- National Fuel Gas Code Latest
Revision.
1. Field connections are made by first removing the
access panel for the heat section on the front of the
unit.
2. The gas piping assembly ships inside this section and
includes the shut-off valve, a pressure tap for testing,
and the necessary unions for field connection. For
through the base access, remove the factory-provided
cap from the base pan opening. See
Figure 14, p. 22 .
3. Route field piping through this hole to the dimension
shown in Table 6, p. 22 .
4. Place the assembly through the cabinet opening as
shown in Figure 14, p. 22 and make the union
connection to the field piping and to the gas train. Refer
to the
“Heating Operation (for Gas Units) - Standard
Economizer,” p. 25 for startup instructions.
