WARNING
High Voltage!
To avoid personal injury or death due to electrical
shock, disconnect electrical power before servic
-
ing or changing any electrical wiring.

WARNING
High Voltage!
To avoid the risk of injury, electrical shock or
death, the furnace must be electrically ground
-
ed in accordance with local codes or in their
absence, with the latest edition of the National
Electric Code.
Junction Box Relocation
Line voltage connections can be made through either the
right or left side panel. The furnace is shipped configured
for a left side electrical connection. To make electrical
connections through the opposite side of the furnace,
the junction box must be relocated to the left side prior to
making electrical connections. To relocate the junction box,
perform the following steps.
1. Remove the burner compartment door.
2. Remove and save the two screws securing the
junction box to the side panel.
3. Relocate junction box and associated plugs and
grommets to opposite side panel. Secure with screws
removed in step 2.
IMPORTANT NOTE: Wire routing must not interfere
with circulator blower operation, filter removal
or routine maintenance.
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 any unpainted surface.
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 servicing. Do not defeat this switch.
