W.C.), turn off electric shutoff switch located on furnace gas control
valve and accessible manual equipment shutoff valve before and during
supply pipe pressure test. After all connections have been made, purge
lines and check for leakage at furnace prior to operating furnace.
The gas supply pressure shall be within the maximum and minimum
inlet supply pressures marked on the rating plate with the furnace
burners ON and OFF.
Gas entry can be from left or right side, or top panel. See
Fig. 31.
Gas Pipe Grommet
For direct vent (2-pipe) applications, the knockout for the gas pipe must
be sealed to prevent air leakage. Remove the knockout, install the
grommet in the knockout, then insert the gas pipe. The grommet is
included in the loose parts bag. See
CAUTION
!
FURNACE MAY NOT OPERATE HAZARD
Failure to follow this caution may result in intermittent furnace
operation.
Furnace control must be grounded for proper operation or else control
will lock out. Control must remain grounded through green/yellow wire
routed to gas valve and manifold bracket screw.

etc.) full load amps.
‡. Length shown is as measured one way along wire path between furnace and service panel for maximum 2 percent voltage drop.
**. Time-delay type is recommended.

ELECTRICAL CONNECTIONS

ELECTRICAL SHOCK, FIRE OR EXPLOSION HAZARD
Failure to follow safety warnings could result in dangerous operation,
serious injury, death or property damage.
and
Improper servicing could result in dangerous operation, serious injury,
death or property damage.
- Before servicing, disconnect all electrical power to furnace.
- When servicing controls, label all wires prior to disconnection.
Reconnect wires correctly.
- Verify proper operation after servicing.
- Always reinstall access doors after completing service and
maintenance.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Blower door switch opens 115-v power to control. No component
operation can occur. Do not bypass or close switch with blower door
removed.
See Fig. 33 for field wiring diagram showing typical field 115-v wiring.
Check all factory and field electrical connections for tightness.
Field-supplied wiring shall conform with the limitations of 63_F (33_C)
rise.
