Understand the signal words DAN- GER, WARNING, and CAUTION. These words are used with the safety- alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage.
STARTING YOUR
FURNACE
Instead of a continuously burning pilot flame, your furnace uses an automatic hot surface ignition system to light the burners each time the thermostat turns your furnace on. Follow these important safeguards:
•Never attempt to manually light the burners with a match or other source of flame.

•Read and follow the operating instructions on the furnace, especially the item that reads as follows:
“Wait 5 minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B’’ in the above safety infor- mation on this label. If you don’t smell gas, go to the next step.”
!WARNING
Should overheating occur or the gas valves fail to shut off the gas supply, turn off the manual gas valve to the fur- nace BEFORE turning off the electrical supply. (See Fig. 8.) A failure to follow this warning could result in a fire or explo- sion, and personal injury or death.
•If a suspected malfunction occurs with your gas control system, such as the burners do not light when they should, refer to the shutdown proce-
dures on the furnace or see “Shutting Down your Furnace” section in this manual, then call your dealer as soon as possible.
•Check Air Filter: Before attempt- ing to start your furnace, be sure the furnace filter is clean and in place. (See the maintenance section of this manual.) Then proceed as follows:

5.The gas valve will have EITHER a control knob or control switch to turn off and on. Turn the control knob or switch on the gas valve to the OFF position and wait
5 minutes. (See Fig. 12 or 13.)
6.After waiting 5 minutes, turn the control knob or switch on the gas valve to the ON position. (See Fig. 14 or 15.)
7.Replace the access door(s). See Fig. 16 for upflow and Fig. 17 for downflow. Replace control door first on downflow furnaces. Replace blower door and secure with 2 screws.
8.Turn on electrical supply to the furnace. (See Fig. 18.)
9.Open the external manual gas valve. (See Fig. 19.)
10.Set the room thermostat to a tem- perature slightly above the room temperature. This will automati- cally signal the furnace to start. The inducer motor will start, and the hot surface ignitor will ener- gize. When hot, the ignitor will have an orange glow.
