Volt Thermostat Wiring - Goodman xMEC96 Series User Manual

To ensure proper unit grounding, the ground wire should run from
the furnace ground screw located inside the furnace junction box
all the way back to the electrical panel. NOTE: Do not use gas
piping as an electrical ground. To confirm proper unit grounding,
turn off the electrical power and perform the following check.
1. Measure resistance between the neutral (white) connection
and one of the burners.
2. Resistance should measure 10 ohms or less.
This furnace is equipped with a blower door interlock switch which
interrupts unit voltage when the blower door is opened for servic-
ing. Do not defeat this switch.

Low voltage connections can be made through either the right or
left side panel. Thermostat wiring entrance holes are located in the
blower compartment. The following figure shows connections for a
"heat/cool system".
This furnace is equipped with a 40 VA transformer to facilitate use with most cooling equipment. Consult the wiring diagram, located
on the blower compartment door, for further details of 115 Volt and 24 Volt wiring.
As shipped, the furnace S1-1 switch is OFF; S1-2 switch is ON. This is the correct position to use a single stage heating
thermostat with auto timing transition to high fire.
