WARNING
HIGH VOLTAGE!
To avoid the risk of injury, electrical shock
or death, the furnace must be electrically
grounded in accordance with local codes or
in their absence, with the latest edition of the
National Electric Code (NEC).
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 the 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 the unit voltage when the blower door is opened
for servicing.
NOTE: Do not defeat this switch.
NOTE: Wire routing must not interfere with circulator blower
operation, filter removal or routine maintenance.
Low voltage connections can be made through either the right or
left side panel. Thermostat wiring entrance holes are located in
the blower compartment. Wire routing must not interfere with
circulator blower operation, filter removal or routine maintenance.
Refer to the following illustration for thermostat connections to
the integrated control module terminal strip.
