!WARNING:

Should overheating occur, or the gas supply fail to shut off, shut off the manual gas valve to the furnace before shutting off the electrical supply.

Ifanyoftheaboveconditionsarefound in the vent pipe, call a qualified service technician to install new vent pipe.

For 80+ upflow and downflow models only: Burner Maintenance (NOx), If the second or eighth character of the model number is an “N” the furnace has factory installed NOx reduction inserts. The inserts reduce the NOx emissions of the furnace. The NOx reduction inserts are located in the first pass of the top portion of the heat exchanger. When the burners are operating, the flame should extend through the center of the NOx reduction inserts. The flame color should be blue, however some light yellow streaks may occur on the outer portions of the flame.

Inspect the burners, mounting brackets, and all other parts in the vestibule for signs of deterioration. The burner vestibule should be vacuumed clean and inspected annually.

!CAUTION:

Do not strike any of the internal electrical components while vacuuming.

These furnaces are equipped with roll-out limit switch(s), a vent safety switch, and a pressure switch (See Figures 1, 2, 3 and 4). The pressure switch verifies that the flame is receiving combustion air. If the flame is not drawn into the heat exchanger tube, the roll out limit switch or flame sensor, will shut the furnace down.

The vent safety switch shuts the furnace down if the vent becomes blocked or restricted.

1)Is the thermostat operating properly?

2)Are the blower door(s) in place?

3)Is the furnace disconnect closed?

4)Has the circuit breaker tripped (or fuse blown)?

5)Is the gas turned on?

6)Is the filter dirty or plugged?
