Carrier Starting and Shutting Down Your Furnace: 58MCA, 58MVP, 58MXA Instructions

STARTING AND SHUTTING DOWN YOUR FURNACE

Instead of a continuously burning pilot flame which wastes valuable energy, your furnace uses an automatic, hot surface ignition system to light the burners each time the thermostat starts your furnace. Follow these important safeguards:

7

•Never attempt to manually light the burners with a match or other source of flame.

•Read and follow the operating instructions on inside of main furnace door, 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 safety information above on this furnace label. If you don’t smell gas, go to the next step.

•If a suspected malfunction occurs with your gas control system, such as the burners do not light when they should, refer to the shutdown procedures on inside of main furnace door, or in the “Shutting Down Your Furnace” section and call your dealer as soon as possible.

!WARNING

If overheating occurs or the gas valve fails to shut off the gas supply, turn off the manual gas valve to the furnace BEFORE turning off the electrical sup- ply. (See Fig. 9.) Failure to follow this warning could result in a fire or explosion, and personal in- jury/death or property damage.

•CHECK AIR FILTER: Before attempting to start your furnace, be sure the furnace filter is clean and in place. See “Performing Routine Maintenance” section in this manual. Then proceed as follows:
