3. As shipped, the rollout protection device is located
near the flame sensor end of the manifold assembly.
Remove and save the mounting screws.
4. For most installations, it will not be necessary to
remove the wires from the rollout protection device.
5. For horizontal-left installations, a hole is provided
near the ignitor end of the manifold assembly. Insert
the rollout protection device into this hole and attach
with screws removed in step 3.

6. Secure rollout wires to manifold and insure no wires
can come in contact with burners or other hot sur-
faces.
7. Push the button to confirm the rollout control is in the
closed position.
8. Replace the cover on the burner box, placing the
screws from step 2 in their original locations.
WARNING
To prevent death, personal injury or prop-
erty damage due to fire or explosion, a
qualified servicer must determine the rea-
son the rollout protection device opened
before the device is reset.
Burner Box
This furnace must use indoor air for combustion. It is not
a direct vent furnace, and it cannot be installed as a direct
vent furnace. The burner box (on some models) is
present only to reduce the burner sound transmission.
Reset After Control Lock-Out
If ignition has not been achieved for any reason, the
electronic control module will lock-out the furnace. A lock-
out causes both the air blower to run continuously and
ignition is no longer attempted. When this occurs, it may
be necessary to reset the control by turning the thermo-
stat setting below room temperature and then returning
the setting to the desired temperature. The control may
also be reset after a lock-out by turning off the electrical
disconnect switch to the furnace. The control will auto-
matically reset after one hour.
IMPORTANT: If the furnace requires frequent resetting
for satisfactory operation, a problem exists with the
furnace. Contact a qualified servicer for further informa-
tion.
Auxiliary Limit Control (Figure 35)
A manual reset limit is located on the blower side of the
blower deck, near the center. To access this auxiliary
limit, disconnect the electrical power and remove the
blower door. If the limit control opens, the air circulation
blower will run continuously. The diagnostic light will flash
four times. These symptoms are identical to a trip of the
primary limit control. See Section IX for diagnosis.
The auxiliary limit control is designed to prevent furnace
operation in case of main blower failure on horizontal and
counterflow installations. It may also open if the power
supply is interrupted while the furnace is firing.
The auxiliary limit control is suitable for both horizontal
right and horizontal left installations. Regardless of air-
flow direction, it does not need to be relocated.
