Carrier Furnace - Manual (Page 34)

Read and follow the operating instructions on inside of
main furnace door, especially the item that reads as fol­
lows: (See Fig. 3f,)
“Wait 5 minutes to clear out any gas. Then smell for gas,
including near the floor. If you smell gas, STOP! Fol­
low “B” in the safety information on 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 Fur­
nace” section and call your dealer as soon as possible.
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. Do not run the furnace without a filter in place.
